A client came to me because his former LCSW therapist was hospitalized and undergoing a long-term recovery process. During our first session, the client disclosed an inappropriate, sexual relationship with his former therapist. In a subsequent session, the client named the former therapist, who happens to be a colleague and personal friend of mine who is in private practice.
Approaching the therapist would violate the client's HIPAA rights, yet I am now privy to information about another therapist that violates state law and NASW guidelines. What should I do?
