If I am crazy enough to do this again, there will be no hesitation in calling on GGC to do the work for me.
Cathleen MalleryStore Owner, Edible Arrangements
GGC foreman are professional, thorough, no nonsense, and independent. They work wonderfully with tenants and local inspectors.
Lori MoranVice President, Ballymoney Real Estate Services, Inc.
GGC has tackled a wide range of assignments for me, and has approached each of one of them with their own unique brand of enthusiasm and expertise. I often rely on GGC for support on time sensitive matters, and have always been completely satisfied with the outcome.
Terry JackovicDirector of Store Construction/Real Estate, American Eagle Outfitters
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.
