Let me tell you a little bit about us, Colosimo Electric Construction. My name is Robert Colosimo. I started this business in 1987 immediately upon passing the City of Buffalo Master Electricians exam. Prior to that I had worked for 10 years for Irwin Davis Electric. My goals were simple. To have moderate growth as an electrical contractor but to always remain "grounded" and maintain the great service that my customers have come to expect from us. We are always working hard to keep up those standards.
