Derian GC - Custom Pools & Construction

Derian was rock solid from beginning to end. In spite of the world-wide shortage on just about everything you need to install a pool during the summer of 2021, they came through with high marks. The pool itself came out stunning, and we used Derian for design too. As well, the rest of the surrounding work they did (deck, hardscape, turf) was equally great. I knew we were going to love the pool. I didn't know we'd love it THIS MUCH. Great, great job.

Kerri and Billy of Derian GC just helped my wife and I with a complete back-yard transformation which includes a pool, spa, outdoor kitchen and hardscape. They were helpful, communicative and had great advice throughout the process and their crews were friendly, professional and detail oriented. They helped us navigate the complexities of permitting and inspection and we couldn't be happier with the end result!

Had a great and seamless experience working with Derian GC. Hired the team to build a very large fountain in my backyard in the West Hollywood Hills which was difficult due to consistent construction on sunset plaza and the fact that they had to dig out the space by hand because no machinery could logistically be brought behind the house. The team was very professional and my neighbors even mentioned to me how professional they were, especially Kerri. The fountain turned out better than expected and is loaded with easy technological features I can access with my iphone. Every was smooth and easy from initial design phase to post completion. Expert, artistic, and genuine people who communicated very well. Highly recommend!

We recently needed the coping and tile around our pool and hot tub fully replaced. In addition, we also wanted the counter surrounding our outdoor BBQ and sitting area redone. Through a recommendation, we were introduced to Derian GC. Kerri and her team worked closely with us on the design, materials and timeline. As promised, the work began as scheduled. Throughout the entire job, the updates and communication provided by Kerri was outstanding. In addition, the work done was of the highest quality, with Kerri's entire team fully committed to doing the best job possible, in a timely fashion, and on budget. To their credit, they met all of those goals, and we are thrilled with the finished and final product. There is no hesitation on our part in giving Derian GC, Kerri and her whole crew our highest recommendation! Keith & Colleen Suddaby

We have been extremely impressed with Derain Pools. Keri in particular is on top of every job to ensure on time and high quality production. They resurfaced our entire pool, installed new color lights and an ozone filtering system and it looks amazing. We also endorse Derain Pools to do more than just pools - they just completed a huge project to expand our driveway for a large boat storage area. Her crew worked through high winds and even some rain to get it done on time. Thank you Keri and thank you Derain Construction for your excellent work. Laurie and Ron Pettibone

Working with Billy, Kerri and the entire crew of Derian Pools was an absolute pleasure. From the beginning of the project with Billy to the execution and completion with Kerri, the process was flawless. Their crew was always polite, responsible and punctual. We had such a great experience that we extended the scope of works to include demolition, retaining wall construction and paving over a new concrete base that they laid. The whole project was on time and on budget. I would not hesitate to recommend Derian Pools most highly!

We had a great experience working with Kerri & Billy. We live in a mid-century modern home and Billy did a great job visualizing the transformation of our back yard and then developing a plan. Then came Kerri and her great crew to make that plan happen. They are not only very professional in what they do, they are an absolute pleasure to work with. We are loving our pool with waterfall and outdoor kitchen and are very thankful for the work they did to make it happen.

Kerri of Derian Pools made the construction and installation of our pool really stress free. She and her crew were courteous and extremely professional. They offer a complete package according to one's needs from design to finish product. This is the second time we've used them and will definitely continue to use them for our future projects. We're highly satisfied with their work and we highly recommend them.

My wife and I really enjoyed working with Kerri, Billy and her crew on building our backyard oasis! The project was a complete success and came out amazing. They were super helpful in giving us ideas along the way and not being shy on product and color recommendations. They were extremely hard working and quick, but had just the right amount of attention to detail where it mattered. Kerri was always extremely fast at getting back to us on any questions we had, even on a weekend. She even went the extra mile for us when we had a heater issue months after our project was completed. She handled the the whole warranty process for us and had someone out next day from the manufacture to replace the bad part. Thanks for everything!

Our pool was finished in January and we have become the most popular family with all of our kid’s friends! The project went smoothly and Kerri was great to deal with! Would highly recommend Derian Custom Pools!

My beautiful pool was just completed by Derian Pools and construction. The building of the pool was a smooth and timely process. Scheduling for each step occurred without delay. The workmanship is excellent. They were prompt with communication and responding to all my questions. I highly recommend Derian Pools. They built a beautiful show-stopping pool for me.

Most people will not recommend their contractors. None of my friends would give their worst enemies the name of their pool contractors. I will . I am actually sad in a way that our project is coming to an end. Final city inspection is tomorrow. What a joy this project of transforming my yard as been. Kerri and her team are so special. They were here every day working long hours and very clean, (since I am OCD that's important.) They are courteous , honest and work in the time frame promised . All of Kerri"s subs are fabulous as well. Billy does the design work and has a great eye. You wont be disappointed ,they truly are wonderful, and I am picky.

Kerri McCoy of Derian Pools is the best pool designer, builder and innovator in the pool business. Her company can build in easy or difficult locations and her workmanship is flawless. She designed and built our salt water zero edge/infinity pool on time and on budget (pictured on Derian/Houzz page). She even has a crew to do a weekly pool service who are also fabulous. Our architect recommended several other companies in addition to Derian but we made the right choice with Kerri. We recommend her and Derian Custom Pools with no hesitation and great enthusiasm.

What a pleasure to deal with Keri and her crew. They came in from the start as professionals are supposed to do. The crews where always here when they said they would be and they always did what they told me they were doing. I was always kept informed of the progress ad next step. Armando who was the lead on the job is a gem. He would always take a moment for a question or any concerns I may have had The best part of dealing with Derian pools is when I left a call or a text for Keri, a return call always happened.

We had a great experience working with Derian Pools. The pool and the hardscaping turned out great. The team has been very responsive after the project was completed as well. We recommended them to our friends as well.

I've worked with Derian pools for years as a consultant and designer and can tell you they are a top notch pool and construction firm. They do amazing work, on time and on budget! If I was building a pool in LA, they would be the first and only company I called to get it designed and built!

We subcontracted Derian Pools and Construction to refinish a clients existing swimming pool. We were so please with the ease of communication, pricing structure, etc... and the client was absolutely thrilled with their new pool.

We worked with Kerri and Custom Derian Pools on two separate projects now and have been so impressed. Pricing is competitive, service is far above their competition. We will continue to use them for all of our pool needs!

When we purchased our home, we knew right away that we wanted to change/update a few of the areas, both interior and exterior. Being a designer myself, working with someone with innovative ideas was very important! Our first encounter with Derian Pools was with Billy the salesman and designer ... he was nothing but professional, super friendly with creative ideas and easy to work with. Once we established what we would be doing to our existing garage and backyard, we were introduced to Kerri. She is super professional as well! Very thorough and knows her business like no one we have encountered. The end result of our projects were nothing short of amazing! Their crew was friendly, clean and respectful! I would recommend Derian Pools and Construction over and over again, as the projects we had done by them have given us many fun memories in our home with our family and friends. Thank you guys! NOTE: Projects done ... *converted existing garage into a game room/bar with exterior courtyard *backyard was flat when we moved in - they created a huge wood deck with barbecue bar, herb garden and outdoor sink, covered spa, built in bali bed and the landscaping surrounding. Built us an outdoor vineyard room as well as fire pit area (great for our kids)

I had the pleasure to work with Kerri this year as a subcontractor. Kerri was professional and responsible. Her crew displayed great work ethic and did an amazing job preparing the forms and reinforcement before our pour day. I recommend Custom Derian Pools for a job well done and great customer service.

Kerri and her team made a beautiful zero edge pool for us. They did an exceptional job and we highly recommend Derian Pools & Construction!

We've worked with a lot of contractors in fixing up our single family home, and Derian has been far and away the best. From initial design/pricing stages to project completion, everyone involved was punctual, honest, and respectful. Our pool and hardscaping project was comparatively small but we received A+ customer service and attention anyway. Working with Kerri to coordinate the project was fantastic from start to finish. She was very communicative and made good aesthetic suggestions for the project. The construction team was easy to work with, very careful with our property, and meticulous in their work.

Derian Pools: Dream, Design, Deliver! We bought a fixer upper with an old pool from the 1970s. We knew we wanted to remodel with a midcentury modern design, but my husband who lives in the pool, also wanted a jacuzzi! My biggest concern was that the design and execution were delivered efficiently. After contacting multiple contractors, and asking many questions, we felt most comfortable with Derian Pools. Compared to other bids we received, (6 total), Derian Pools communicated with us and heard our vision, implemented their feedback based on their extensive experience with luxury pools, and was forthright about cost every step of the way. Keri has managed to pull together an expert crew whose work we witnessed firsthand for a two month period. From design, forethought, demolition, clean up, and every aspect of construction, the job was supervised efficiently and it progressed at a steady pace within the timeline offered. We had a slight setback due to rain (3 days), but nothing major considering the extent of the job. Our backyard is our favorite place to be...and our mid century modern pool is the crown jewel. We host many parties and it has been a pleasure to recommend Derian Pools to everyone that has asked. We can confidently do so, because the level work they deliver leaves zero room for regret!

She has just finished our pool and it is beautiful. Many unique features and an outdoor kitchen that is a dream to work in. Ms McCoy is easy to work with and made excellent suggestions. This is the third time I have worked with her and she continues to amaze me with her creativity and hard work.

Kerri was very professional and efficient. We were given an estimate of 5 weeks for construction and she delivered. We had a pool filled with water in exactly 5 weeks. We trusted Kerri completely with the process and the communication was great. She listened to everything we wanted. We highly recommend Kerri and her crew as I have already recommended her to multiple friends who are currently using her.

Derian collected over $100,000 from us, then abandoned the job, leaving a tremendous mess, refused to return even to clean it up, did not even mark the pipes and refused to cooperate in doing so for the benefit of another contractor, did a terrible job, many parts of which have to be fixed or redone. During the shotcrete pour, the hose broke, shooting shotcrete onto our property and beyond, and causing serious damage. Derian refused to turn it over to its insurance company even though the contract provided that we were to be named additional insureds, and then refused to provide documentation leading us to conclude that we were never named additional insureds even though we paid for that. We had to file a complaint with the Contractors' Board, which is being investigated.

Derian Pools just finished our backyard/pool project and we are thrilled with the results. The project was completed as scheduled and budgeted. All of the sub-contractors and Derian employees were very easy to work with and did an excellent job. They were hard working, neat, and respectful of us and our neighbors. Kerri communicated regularly and kept us updated throughout every step of the project. The final product is exactly what was envisioned through our 3D design images. The designer, Billy Derian, did an excellent job of listening to our wants/needs and created our perfect backyard oasis. We would highly recommend Custom Derian Pools to anyone looking to create a dream backyard!

We knew we had the right team from our first meeting. Billy came out and looked over our yard talked to us and immediately walked us through a plan that made sense for our home was in line with our design taste and solved the issues we had in our yard. It was a massive project of clearing out a large backyard the previous owner had left overgrown full of random plants and planters and shrubs (like a horror movie) and a yard that leveled up in the main portion with an odd ledge on the side. Then he looked at the front yard walked around it identified some design issues we had not thought of and suggested exactly what we went with.After the design and contract process (which was great and they worked with us on budget) Kerri took over for the construction This was a large project including front and backyard complete redesign, building a pool and hot tub, boccie ball court and fire pit. They were incredibly timely and the people working were great (side note, they were really sweet to my six year old who was curious about what they were doing and wanted to talk to them every Saturday) . The results are hard to describe. The backyard is an oasis and the front yard has curb appeal but is functional for parking. We are enjoying the pool every weekend and just used the fire pit for s'mores and the genius concrete bench that is attached to the pool.The transformation is unbelievable and anyone that sees it and has work to be done asks for their information. They were easy to work with through the process. I have and will continue to give out their contact to friends! I still text Kerri with random pool operation questions and they are 100% responsive and set us up with a pool service that is great. When they finished the first major project we knew we had to keep them for a smaller project we had in mind which was redoing our outside shed and taking a wall down in our house opening up the garage and building a bar. We immediately tacked on the work so they stayed on and the whole thing looks amazing. We have a more open area in the front of the house with a cool bar and the shed is stunning in a bright blue with an amazing design on the door. Here again they took time to make it really special asking my six year old for her favorite shape and designing the front shed door detail around it. So much resale value and also so personalized to us an our lives (with a 6 year old) Having worked with a couple contractors in the past I can say that these guys are the exception. Truly first rate.

I do have to start by saying that I don't think I have ever given anybody a 5 star rating before and I am proud to say this is my first. Building a pool in your backyard means building a relationship with a team that you trust, completely. From the moment I met Kerri and Billy (who helped put stunning design plans together) we clicked. I had a vision for our backyard and they immediately understood what we were going for. We had a tight deadline as we wanted to have our wedding reception and family over in our backyard over the summer and Kerri explained that she would do her best to ensure our backyard would be ready. And boy.. did she deliver. BBQ, Fire Pit, entertaining space, private curtained deck area off the bedroom, Jacuzzi, Pool, Waterfall, Planter boxes... It's like a tropical oasis that I get to enjoy every moment of every day. The team was reliable, kind, and one of the most hard working crews I've ever seen. Whenever I came home from work, everything was always put away and cleaned up so I never had to worry about my dog getting hurt if he was running around the yard. From design to execution to price... I think Derian Pools & Construction has the best out of anyone I've spoken to. I have no doubt in my mind that if you go with Derian Pools & Construction, that you won't end up 100% satisfied as I did. Don't get me wrong, there were a few bumps along the road, as there will be with any home renovation project, but Kerri was with us every step of the way to guide us and make sure our project turned out to exactly how we imagined it would. Please see below for a few pictures from a few months ago..

Pool came out beautiful. I honestly could not have asked for a nicer pool. It was everything I imagined. Kerry was there for us during the work and made sure that we knew she would stand by her work if there were any problems..

We used Derian Pools for construction to design and update our backyard. We were very happy with the professionalism and care both Kerri and Billy provided. The project was completed in a timely manner and there was fantastic communication though out the process. I would highly recommend them to any of my friends and plan on using Derian Pools and Construction for and future jobs!

Custom Derian Pools is the gold standard in contracting. We did a major remodel (pool, bbq, half basketball court and fire pit). Despite the heavy rainfall, the project moved quickly and turned out beautifully. Billy helped us envision our dream backyard and Kerri made it a reality. We can recommend them with confidence that they will treat their customers right.

Kerri is amazing. Her knowledge of pool consruction, cutting edge designs, and respect in our industry is right along with the best. I've worked with her and asked her advice many times and she is both helpful incredibly knowledgeable and super helpful. Everybody in the pool industry knows her and respects her, because she's proven herself to be among the best! I highly recommend her. Ben Aguirre, Owner Ben'z Pool Biz

We love Kerri's honesty. She gives you all the facts and provides her professional opinion to make sure you get the best quality without spending a fortune. She is extremely knowledgeable in all facets of pool design and even has great experience in landscape design. She is responsive, and reliable and follows through with what she says she will do. We fully trust Kerri and Billy at Derian Pools and we are glad to serve as a reference anytime.

Kerri was the go-to person for my pool project. I hired Derian because of its reputation and they did not disappoint. I lived in SoCal at the time I had the pool built and I have never been so happy with a project. Everything was finished on time and beautifully done. Kerri is a good listener and provided everything I wanted in the way of a pool and Jacuzzi. I would hire Derian again if I sill lived in the L.A. area.

Keri, worked on Best Western in Redondo Beach, CA on second floor pool and spa, Scope was to replaster, new water line, pool coping and LED pool light. Assisted with a under ground water leak, that was beyond her scope for no charge. Keri, as client driven, was ahead of scheduke, and worked with my budget to assure I was below my projected cost.. Ken Mauck

Wanted a unique design and not your average pool , spa, fire feature, BBQ bar. Derian designed the perfect environment while showing us new ideas. The price was competitive and the finished product is total high end hotel quality. The crews were clean and nice to work with. They were very close to the deadline to finish date. Super happy. Thanks Billy &. Kerri

I have worked on a few projects for Derian Pools and found them to be very knowledgeable in there scope of work. They are detail oriented and the owner is very attentive. I enjoyed working for them and would do so again in a heartbeat.

I was reluctant to get my pool redone because I have have numerous bad experiences with contractors. I just didn't want to deal with another flake, that says they are going to do something but once they get paid, the rules change. Well let me tell you, Derian Pools has restored my faith in contractors. They came in accessed the job, gave me an estimate and after we agreed to go forward, they hit the ground running. They did what they said they were going to do, for the amount of money that we agreed on and did so in a quicker time frame than was originally agreed upon. Along they way, the employees were polite, cautious and clean. I couldn't have asked for more from them. Without question, I would highly recomend Derian Pools to a close friend or anyone for that matter. Thank you so much for a job well done.

I used Kerri for a pool I had in a sales transaction! She was professional, fast and got everything completed on time. She did an excellent job! I highly recommend her for clients and even other realtors! Thanks for your outstanding job!

Derian did an outstanding job of completely rejuvenating a 25-year old pool and spa at our HOA. The work included reconstruction of a large (1200+ sq. ft) concrete deck. The messy demolition of the deck and pool went smoothly and Kerri McCoy of Derian was very considerate of homeowners' concerns regarding noise and dust. The reconstruction work was done with obvious expertise by the subcontractors, but Kerri was on top of every step, and was always responsive to inquiries from our property manager and Board. There were some delays, due mostly to scheduling inspections. Otherwise, the work was completed on time. The HOA is very pleased with the result. We highly recommend Derian, for the quality of their work, their attention to the client, and their fair pricing.

My husband and I had an old school 1958 pool in need of a serious update. Derian Pools created a magical new pool and outdoor fireplace for us. They designed a Baja bench in the pool we never would have thought of, and we enjoy it all the time. The new Jacuzzi and waterfall effects are gorgeous. They are true professionals from design through completion. A great team ! Kimberly + Adam Encino, Ca.
