Mainstream House is centrally located in Riverhead, The County Seat Of Suffolk County. Mainstream House is a working mens' sober house, with a tested structure that re-establishes healthy habits in the recovering addict.

Mainstream House was founded by Robert Hartmann to give recovering addicts, like himself, a safe home to recover from chemical addiction. By requiring residents to attend 12 step meetings, and get a sponsor. Mainstream House introduces the client to the tools needed for long term recovery.

Mainstream House is a working house which means the client must get a job early in his stay. This approach teaches the addict some of life's lessons that were forgotten in addiction; how to pay bills, how to manage your money, and how to save for the future.

A curfew is initially required. The curfew is decreased as the client recovers, and is eventually waived once the client reaches 4 months in the house. This curfew teaches clients how to manage their time and how to have a healthy schedule in recovery.

Each week a house meeting is held by the clients. They gather to disscuss matters affecting the house, their recovery, and to divide the chores of the house among themselves. This teaches the clients how to work together, how to express their concerns in a healthy manner and how to treat their homes and others with respect.

As the clients recover togethe, life-long friendships are developed. Clients form a support group of other recovering addicts, both in, and outside of their house, that they can turn to in times when support is needed.

We keep in close contact with our alumni, both those still living in the area, and those across the country. We have often formed close bonds with them and life-long friendships. Mainstream House looks at both our current clients and alumni as family.

Mainstream House uses a tested and effective approach to aiding in recovery; by providing a safe/clean environment and by encouraging the healthy growth of a recovering addict. We have seen countless lives turned around.
