GGC National Contractors was founded on the principles of sustainable construction in November of 2009 by Jennifer and John Castellano. The husband and wife duo have been deeply engrained in the construction, mortgage and property management industry for nearly 35 years. GGC National Contractors (formerly Go Green Construction) contributed to the green building movement that was taking the country by storm and as the company evolved, our core competencies began to mold the GGC of today.

We quickly discovered that many of our customers were in need of a reliable retail and office general contractor capable of executing projects in all locations across the country, and with a qualified staff already in place, GGC National Contractors was born. Having quickly become known as a qualified national retail contractor GGC’s work can be viewed in nearly all 50 states, making us extremely proud of the partnerships that we have forged throughout the years.

At GGC our goal is to provide our customers with a frictionless experience during what can often be a stressful process.

Let us bring your vision to life and add your organization to our list of satisfied customers.

If I am crazy enough to do this again, there will be no hesitation in calling on GGC to do the work for me.

Given our experience with GGC as both a recipient of their work through the landlord and as a direct customer, I highly recommend their work and staff. They are definitely on my bid list for our next project in any market they serve.
