About Us

Design Philosophy

TMD Designs, LLC is a full-service interior design firm that creates high-quality design solutions for both commercial and residential environments. We take pride in providing our clients with excellent service and measure success by a high rate of repeat business. Our distinctive design philosophy is to carefully listen and truly understand our client’s needs so that we design the interiors with a “sense of place”. The design concepts should reflect the regional and cultural influences found within the locale as well as compliment the architecture. Whether we are designing a high-rise urban residential housing project or a senior living community in a rural setting it is important to develop the interiors to enhance a sense of community. Another design philosophy we often apply towards our healthcare projects is to bring elements of the outside environment inside the building and use lighting that replicates natural light to enhance the healing process. Each project is unique, and the interior design should always reflect this philosophy.

TMD’s team structure embodies our collaborative approach to interior design which is made up of design professionals with a diversity of skills and experience. Our team members are experts within their respective focus of the interior design field. We approach every project with extensive research and stay current on industry trends within our profession. Additionally, we will often partner with specialty firms to provide our clients a full spectrum of services such as interior architectural design, lighting design, historical restoration/renovation as well as furniture/furnishings procurement and installation. Since our services are available on a consulting basis, our clients can elect to use any part or all that we have to offer. Our primary goal is to create a well conceived and intelligent design for our clients.
