"Gary possesses a breadth of knowledge and a contagious passion that not only inspired me and our staff but also our clients and project teams. He easily conveys concepts, ideas and strategies in simple terms and when required technically detailed. He eloquently highlights synergistic, pragmatic connections between economic viability, building systems, and the occupants’ experience.

" Gary is ecoPreserve’s LEED expert. He consistently demonstrates the highest level of technical proficiency. He's not only technically astute with green building strategies and solutions, he's a natural leader guiding clients through obstacles with make-sense solutions.

 I enjoy working with him and am proud that he is part of our team. 


He does a phenomenal job with communication on all projects Gary! What a pleasure it is to work with such a competent professional.
