With literally decades of addiction experience, and countless clinical hours spent researching, training and treating dual diagnosis issues, our rehab physician and psychiatrist San Diego team is ready to help. Despite our staff pedigree, the key difference at APEX is our team collaboration, coupled with our philosophy and humble touch. We believe every member of our team is reliant on others perspectives and insight. We treat every participant with respect and dignity, not from a place of superiority or judgment.

APEX rehabilitation physicians are hand selected for their ability to work and promote an integrative treatment approach. No one person has THE answer, and only as a team of professionals, working with the participant and family, can we bring the results we know people are striving for. Our clinical staff is tireless in their dedication to wholeness, health, and excellence. Our constant drive for knowledge, continuing education, and goal of the field, participation as leaders in the recovery community, allows our APEX team to be sought after and exceptional at treating not just an addiction, but the whole person. This allows for growth in many ways, as each participant finds their own path to meaningful recovery with our drug treatment doctors and administrative staff.
