We have been honored with many awards, but believe that our clients say it best:

Hear is what our clients say:

“The Alexander Group was a pleasure to work with for the 10 months of our design and renovation project. Alex Dean and his team listened well, offered creative and effective ideas, were flexible and cost conscious, and acted on a daily basis in a client focused manner that was greatly appreciated by my wife and myself. We are one of the few couples who can honestly report that it was a pleasure to work with their contractor, and we continue to enjoy living in the product of that collaboration.” — EH
