Jun 15, 2016 Report
We have been very happy with the services of Omni Design Group, and more specifically, our architect Jon McAlpin. We interviewed 4 other design firms and hired Jon because he possesses an intimate knowledge of the coastal zone restrictions, is a good listener, and has a good eye for design.
