About Us

As architects, we like to say, “We turn raw ideas into plans for comfortable, livable, inspired buildings and residences”, our tag line. We create more than a house; we create a lifestyle! I work with each client to develop details for his/her single-family residential project or condominium to make the project special. We educate each client for whom this is his/her first addition, remodeling, or new house and make the process as easy as possible, from initial design through permitting to final construction. I have a passion for residential work where I try to make our tag line come alive. Many firms delegate you and your project to an associate in the firm. In my firm, you will deal with me. You will make decisions jointly with me. We will make the project a success together. Because of our success as creative and detailed architects, our firm has been creating successful projects for 30 years. United Architects was founded in 1986. Our residential work has been featured on HGTV. I appeared on Tropical Currents with Joseph Cooper on WLRN in Miami. As the principal of the firm, I am a registered architect in the state of Florida. I hold a Master of Architecture degree from the Georgia Institute of Technology (Georgia Tech). We welcome the opportunity to talk about your project and offer practical solutions which are beautiful at the same time. Call me at 305-439-7898. ________________________________________________________________ We provide architectural services for commercial, residential, and institutional projects.
