Mike Maples

Project Manager

Mike comes from a family that grew up in the construction trades.  He has a vast background of experience in field craft as well as construction management.  He grew up working with, and learned from, his father, who is one of the finest stucco/plaster/carpentry tradesmen in the business.  He also worked with a general contractor in the Midwest, where he received an abundance of knowledge in construction/management. ,Mike owned his own successful stucco and plaster company for many years, which is where I met him.

Mike was looking for a more stable economic environment when his father suggested I talk with him, and I hired him immediately as our Lead Carpenter.  I got to witness his people skills as well as his construction skills.  Our clients all rave about him and our trade contractors and suppliers respect him.  It was not long after that I promoted him to Project Manager, and he has flourished in that role.  You will enjoy working with Mike.
