Providing exceptional service in interior design and
architecture utilizing a collaborative approach dedicated
to attaining client's goals.


TDA provides an experienced team of interior designers and architects committed to providing exceptional service to our clients. We use a team approach in completing projects. Most clients require us to lead the design process while others require a professional assist. Either way the client is an integral part of the design team. We are extremely flexible with the scope of service we can provide and never approach a project with preconceived solutions.

TDA remains available as a consultant to other AE firms who require the depth of interior design experience we offer.

TDA is a strong advocate of utilizing both methods and materials that reflect responsibility to our environment. We approach projects with the level of sustainable or Green design that reflects our client’s objectives. With LEED accredited staff and USGBC membership TDA can assist in generating the design and documentation required for LEED certification.


Since 1990, TDA has provided professional services to Cincinnati, the tri-state region and selected national locations. Our firm excels in personalized service, delivering quality design, utilizing relevant technology and adhering to budgets and schedules. We are known for our quick turn around capabilities, creative solutions, ADA compliance consultation, and application of BOMA guidelines/recommendations.
