Her creative brilliance shows up in every design and every piece she selects to outfit our office. Her process in getting to know her clients is thoughtful and deliberate as she marries individual preferences and personalities to the overall vision of the entire space so there is a rhythm to the landscape that flows beautifully. She is timely, communicative, and a definite problem-solver. We are in Phase I of our project with her and we just had our preliminary reveal. We were WOWed!!! The time and detail Mrs. McCauley put into every single concept shows her love for her art and her dedication to her clients. We celebrated with a toast and tears as we rejoice in the ability to return to the office post-pandemic in a space that is indeed serene and conducive to getting our work done in a high-stakes, fast-paced field.

I gave Trenell a budget and she came through with such amazing results. Window treatments, wallpaper, and great general contractors. Without second guessing I will definitely use her services again. **Comment from Serenity Interiors by Trenell, LLC:** > Thank you so much for the kind words. It was a pleasure working with you and being part of your business dreams to open your new storefront. Thank you for trusting us. We wish you and your family much success with your new new store and look forward to helping you design your next storefront. **★★★★★ — Dylan Uscher, Dec. 2023** > Trenell was amazing to work with. Not only did she help me design the spaces in my new home and source furniture, she worked with the contractors that did all of the plumbing, electrical and painting work that needed to get done as well. It made the entire process easy, enjoyable, and fast! Trenell has a great sense of style and allowed me a lot of input which was great! Highly recommend Trenell for any design needs! **Comment from Serenity Interiors by Trenell, LLC:** > Dylan, it was my pleasure to work with you. You were the ideal client in so many ways. I must admit your home was so much fun to design because you weren't afraid to step outside of your comfort zone, which is a designer's dream! Thank you for the kind words and allowing me the honor to design your new home. **★★★★★ — Shannon Baxter, Aug. 2023** > Trenell and her husband were amazing from start to finish I completely fell in love with my living room and it was a wonderful start to my brand new home.

It was our pleasure to serve you and to execute your dreams of a beautiful and comfortable living room. I look forward to the next project! **★★★★★ — Teresa Handy, May 2023** > Trenell did a complete make over of my living room and dining area. She made the space appealing, but most of all very comfortable. I did not have any idea on what I wanted for the spaces, just shared with her that I wanted a comfortable space. Trenell came through like a champ! There was no decorative detail left undone, from the largest items down to the smallest detail, such as table art/decorations. Her team even programmed the tv they hung for me!! I was very pleased with her professionalism and her attention to detail. > > I have personally visited other homes and commercial spaces she's done, and have been truly amazed! I would highly recommend Serenity Interiors by Trenell to any seeking to create a new atmosphere in their homes or offices. > > Teresa **Comment from Serenity Interiors by Trenell, LLC:** > Thank you so much Teresa for your kind words.

Think of it as the perfect mix of modern posh and cozy comfort. Im so happy to have the best looking apartment of all my friends and now I can’t wait to get my first home and call Serenity Interiors by Trenell! Thank you! **Comment from Serenity Interiors by Trenell, LLC:** > It was such a pleasure working with you. Thank you for giving us the opportunity to create a serene apartment that makes your friends envious. We look forward to working with you again in the near future. **★★★★★ — Michael Powell, May 2023** > Amazing eye for design, excellent customer service. > > We told them what we were looking for and they took the vision in our head and placed it in our reimagined space. **Comment from Serenity Interiors by Trenell, LLC:** > Your project was so fun to create because we had to incorporate so many different styles and colors but WE DID IT and I'm so HAPPY YOU ALL WERE HAPPY! Thank you for trusting us throughout the process. **★★★★★ — HU-434194622, July 2022** > Our kitchen was dark and unwelcoming and we decided to update it. After looking into replacing cabinets and countertops, we realized that the cost would be beyond what we wanted to spend on a remodel, so we reached out to several interior decorators to see how we could remodel without replacing cabinets and appliances. Trenell's vision for updating the cabinets was what sold us on using her services. She had the cabinets modified to draw the eye up and give more visual impact, had them painted, replaced hardware, light fixtures, and countertops. The transformation is amazing! We are very happy with how things turned out and were particularly pleased with her professionalism and dedication to excellent customer service. **Comment from Serenity Interiors by Trenell, LLC:** > It was such a pleasure to work with you and your kitchen is the most liked and talked about when I show it on our marketing materials. Thank you so much for trusting us to transform your space into the beautifully bright space you desired. **★★★★★ — KC, Oct. 2021** > Trenell and her team were attentive to my need to build a room on the lower level of my townhouse, which required the moving of electrical switches and the addition of overhead lighting. They responded well to all of my questions and comments and left with a fantastic finished product. **Comment from Serenity Interiors by Trenell, LLC:** > Thank you for trusting us to transform your space. You were a delight to work with. **★★★★★ — gary bonhom, Oct. 2021** > well ms. trenell was very professional and the guy alex was very respectful and easy to talk to. i would recommend this company to anyone looking to upgrade there living spaces. very time affective. great job still smiling **Comment from Serenity Interiors by Trenell, LLC:** > It was such a pleasure to work with you. I appreciate you trusting us to bring your vision to fruition. ## Selected projects - [Basement Revamp into a Serene Entertaining Oasis](https://www.houzz.com/hznb/projects/basement-revamp-into-a-serene-entertaining-oasis-pj-vj~6662772) - Location: Washington, DC - Photos: 10 - Description: When we were called to revamp this basement, it was a described as a cold and sterile space that no one wanted to be in.

We WOW'd the client, his… - [Carlene Project](https://www.houzz.com/hznb/projects/carlene-project-pj-vj~6661731) - Location: Upper Marlboro, MD - Photos: 3 - Description: This full design project began with only the rough-ins and studs in the bathroom. The husband was very clear that his man-cave's bathroom must be a full bathroom and unisex. He had a very clear ideal of what he expected in his bathroom. During our design presentation, we incorporated every wishlist and far exceeded his expectation. - [Bedroom Projects](https://www.houzz.com/hznb/projects/bedroom-projects-pj-vj~6661742) - Location: Not specified - Photos: 2 - [Hidden Forest Project](https://www.houzz.com/hznb/projects/hidden-forest-project-pj-vj~7349748) - Location: Accokeek, MD - Photos: 7 - [Erion Project - Trusting the Process](https://www.houzz.com/hznb/projects/erion-project-trusting-the-process-pj-vj~7248831) - Location: Bowie, MD - Photos: 16 - Description: Trusting the Process can be uncomfortable when you've never worked with an interior designer before. Our clients had an idea of what they wanted but they were a bit indecisive of what they envisioned. Their sitting room was small, so space planning properly was important. The living room needed to be an area that was comfortable and luxurious. The dining room was once a room for the kids so transforming the room into a full fledge dining room was very emotional because it was an indication that… - [An Entertainer's Dream for the Entire Family](https://www.houzz.com/hznb/projects/an-entertainer-s-dream-for-the-entire-family-pj-vj~7209621) - Location: Glenarden, MD - Photos: 21 - Description: When our clients contacted us about turning their open concept basement into an entertainment basement for the entire family while aligning with their style, we were up for the challenge. The clients mentioned that their children were getting older and they weren't staying home much because the basement was uninviting.

In addition, everyone had their own color they… - [Tenth Remodel Project](https://www.houzz.com/hznb/projects/tenth-remodel-project-pj-vj~7248847) - Location: Washington, DC - Photos: 11 - [Office Rebranding for a Marketing Empire](https://www.houzz.com/hznb/projects/office-rebranding-for-a-marketing-empire-pj-vj~6677863) - Location: Springfield, VA - Photos: 7 - Description: We helped this woman owned business located in Northern VA to transform their office. Initially, when you walked in their office, you were greeted by a conference table and clunky, leather chairs. Their main pain-point was they didn't want their clients to visit the office because it didn't represent their brand and/or mission as a marketing company. After the exploration and inspiration session with our client, we came up with a great design. We used some of the beautiful and bright colors in t… [See all 8 projects](https://www.houzz.com/professionals/interior-designers-and-decorators/serenity-interiors-by-trenell-llc-pfvwus-pf~2081386673) ## Frequently Asked Questions **What types of interior design projects do you specialize in (full-home, single room, remodel support)?** We specialize in a wide range of interior design projects, from single room transformations like bathroom, bedroom, or kitchen design, to more extensive home remodeling support.
