About
Built on Brooklyn Work Ethic
I'm Andre Johansen, and I've been working on commercial HVAC systems in Brooklyn for years — long enough to know that local businesses can't afford downtime and don't have patience for contractors who don't show up when they say they will. GTM Development Johansen was built around one simple idea: do the job properly, be straight with people about cost and timelines, and stand behind the work. Every building in this borough is different, and I've learned to handle all of them — from old warehouses in Bushwick to ground-floor retail in Park Slope. When you call us, you're getting a team that knows this neighborhood and takes the work seriously.
