**★★★★★ — David Cannon Photography, Aug. 2017**

> I shoot photos of interiors/exteriors full-time and so I get to work with some really talented architects, designers, custom builders, and craftsmen. Katie is the cream of the crop and will undoubtedly be known as one of the (if not THE) premier designers in Atlanta and the South. Above and beyond her extreme talent, she is also kind and patient, which made her a joy to work with on my end of the business, and without question are traits that her clients benefit from over the course of a design job. In my opinion, her work is second to none!

**★★★★★ — RJ Harrumph, Jan. 2017**

> Easy and great to work with. They made the design process smooth by providing information for decisions at just the right time. H & L brought our vision and inspiration to life!

**★★★★★ — Christine Law, Aug. 2016**

> Hart & Lock served as the designer and project manager for our new construction build. Katie is so wonderful to work with! She was patient, willing to listen, did not force her ideas on us, and understood our budget. She was able to take our unarticulated desires and help us flush them out into specific ideas and then make it happen. We could not be more pleased with her

**★★★★★ — kellitsmith, Feb. 2016**

> I worked with Hart & Lock on a complete decor rehaul of my living room.  As with most homes, the living room is a central room in our house; knowing this, it was an important room to get right as it would set the tone for our house as a whole.  My husband and I have very little knowledge or understanding of how to decorate a room, so we asked H&L to manage the project with very little input from the two of us.  The project commenced and evolved over approximately two months.  We were given options for a couple of core pieces of furniture and had time to visit stores to test out the furniture for comfort, style, etc.  We were never pressured to make decisions, but given all the time and respect needed.  This was important to us, given the centralness of the room in our family and our house.  When the final decisions were made, H&L managed all elements of the next steps from beginning to end: coordinating the deliveries, working with the seamstress for all custom-made pieces, and everything in between to the final set up.  The H&L team managed the final set up while we were at work, so we came home to a completely new living room.  To say we were blown away is a complete understatement.  It. is. PERECT.  The room is designed to entertain, but also completely perfect for lounging on the weekend.  It's incredibly sophisticated and also perfect for a growing family with a dog and little one.  The entire week following, I was like a kid at Christmas, waking up early to spend time in my living room.  My favorite spot in the whole house is now the chaise lounge sofa.  We have received endless compliments on the room, with the main theme being our room belongs in a magazine.  The room is absolutely beautiful, all thanks to H&L.  H&L has made our house a home.  The team was incredible to work with and I already have another project pending with H&L.  I would recommend H&L to any and all.  The team is kind, respectful, patient, incredibly talented and absolutely amazing at the job.  Anyone who has the occasion to work with H&L should consider themselves not only in amazing hands, but incredibly blessed for the opportunity to work with the H&L team!

**★★★★★ — Trademark Building Company, Feb. 2016**

> We have had the pleasure of working alongside Katie for over a year now on multiple residential projects ranging from 100k - 500k. She truly has a special ability to work with customers that have many different styles and tastes as well has work within our budgets. For us, Katie's experience in the design world coupled with her knowledge of proper construction practices and processes is why we will continue to hire Hart & Lock Design.

**★★★★★ — Stewart Custom Woodworks INC, Feb. 2016**

> We've worked with Katie on numerous cabinetry projects in the past and always appreciate her willingness to listen carefully to her clients while valuing the input of her sub-contractors. Her selection in design, color and detail continue to impress us. Katie works diligently to provide all involved with a positive experience.
