mine was 1992 Far Rockaway, NY. Legal contract drawn by lawyer. My PCP was 15 miles away and we met every Monday. Years later I sold the practice, (I owned the medical center) to St. John's Episcopal Hospital. I worked for them til 2004. Moved to TX.
PS When I sold the practice to the hospital, my SP's wife decided it was HIS practice! 9 months later and a few $$$ the state of NY said it was mine to sell. He got nada. Now he and I got along fine. He was very happy with his "consult fee" every month for years. She was the greedy one.
