 Our History by Greg Berlin

We are a 3rd generation family-run business, owned and operated by Kim and Greg Berlin. Northgate Garage Doors has been located in Marin since 1975 and the Berlin family has been in the overhead door business for over 55 years.

“My grandfather, Marty Berlin, played an important role in the early stage of the door industry in the Bay Area, starting his own overhead door business in 1948, located in San Francisco.

My father moved to Marin in 1975 and started Northgate Overhead Doors out of his garage. Some years later he opened 2 more locations.

I worked with my father as a garage door installer for many years and learned all aspects of the door business; from sweeping the floors, to complex problem solving, to building custom doors the time honored way.

I am proud and thankful to have been able to learn from my father and grandfather. They taught me things you can’t learn from a manual.

In 1992, I took over the residential overhead door division and my father is still doing industrial doors today.”

As a family-run business, living in the same community in which we serve, our reputation is based on your satisfaction.
