He lived the later part of his life in Stockbridge, Massachusetts until his death from cancer. He was survived by a brother, two children and two grandchildren.

Garel was a mentor, instructor and friend to many who exhibited at and made art upstairs at the Lavendar Door, a Stockbridge tradition that was attached to the Austin Riggs Center. Thus, Garel, in a natural way, helped hundreds of emotionally charged psychiatric patients paint their way out of difficulties that were often too complex for mere therapy to cure. So many of the lives he touched were literally turned around by the knowledge that if they applied themselves their art could gain an audience. An audience not judgmental, in a field where most work is done alone: a perfect combination for those trying to overcome the scars left by myriad unusual circumstances too awful to describe here. His art was superb, but his capacity as a lifesaver was unmatched.
