Mark Coffin
Vice President

I’m extremely proud to be associated with GCC for the majority of my career. During this time, I’ve watched us grow our brand and strengthen our reputation as the leading waterproofing contractor in the state of Florida.

My personal growth within GCC began with estimating and sales, learning to negotiate contracts and acting as a project manager on some of the most prestigious projects performed by the West Palm Beach branch. This experience has introduced me to many new contacts within the industry, including owners, architects, engineers and contractors.

Exposure through hands-on involvement has helped me mature as a leader and allows me to guide our employees, pushing them to provide the best possible product to our clients, while providing the most competitive pricing using industry leading products.

Looking towards the future, it’s my desire to build on the relationships and trust bestowed on me and help GCC expand and improve the overall waterproofing industry, while remaining humble and respectful of the journey to this point.
