Mark CoffinVice President
I’m extremely proud to be associated with GCC for the past 18 years of my career. During this time, I’ve watched us grow our brand and remain the leading waterproofing contractor while our branches perform work throughout the state, which I’ve played a significant role.

My personal growth within the company began with estimating and sales, learning to negotiate contracts and acting as a project manager for some of the most prestigious projects performed by the West Palm Beach branch. This experience has introduced me to many new contacts and acquaintances within the industry including Owners, architects, engineers and contractors. This exposure has helped me mature as leader of our men and employees and push them to provide the best possible product to our clients while providing the most competitive pricing and industry leading products available.

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