Medical Team Bios
Most drug and alcohol addiction recovery programs are led by counselors who have little or no addiction training. Enterhealth Ranch and the Enterhealth Outpatient Center of Excellence, however, have full-time, on-site teams of addiction-trained experts, including physicians, psychiatrists, nurses and Master's-level therapists.
These professionals are more than just brain experts. In addition to their extensive training and addiction expertise, they possess a thorough understanding of exactly what both your loved one and your entire family are going through, and they have devoted their lives to improving yours. Please take a moment to get to know them.
