He provides individual, couples, and group psychotherapy to men and women recovering from the effects of childhood trauma and abuse, Posttraumatic Stress Disorder, depression, sexuality issues, and addictions.

He is a Certified Sexual Addiction Therapist (CSAT-), having trained with Patrick Carnes, widely regarded as the foremost expert in the field of sexual addiction and recovery. In 2002 Don founded the California Institute for Sexual Recovery which provides state of the art treatment services for persons recovering from compulsive sexual behaviors and addiction.
