My former therapist (former because I moved away after three years), moved after I was seeing her for about six months. She let me know and it didn't bother me the least, but I know that it does affect many individuals and she prepared people for the move. I liked her new space because it was bigger (she does group work), it had big windows and was very bright and cheerful, and it was more private. I say private because her former waiting room was shared with a chiropractic office--personally I didn't like that part of her old office.
