“ I first met Steve Giammona back in the year 2000 when he was our Mechanical Engineer on a large complex project. He has been our go to Special Inspector since 2008. Steve provides these services for our healthcare facilities, office buildings and hotels. His services are professional and very in tune with the latest building code as well as energy efficient. He is a hands on guy who is a pleasure to work with.”
