Don Nichols PE, LEED AP, AVS
A licensed residential builder, Don's passion for home renovation projects has allowed him to double the size of his home over the last 15 years with various additions, and his nickname of 'Dean' is so strongly entrenched, that even certain family members don't even know his real name!

A family-man at heart, Nathan spends most of his free time with his wife and three young children. Together, they enjoy relaxing at Silver Lake, camping, racing dune buggies, or just playing in the sand.
