Mark Melden at 158 C Avenue in Coronado is a board-certified psychiatrist and addiction medicine specialist who earned his DO from Philadelphia College of Osteopathic Medicine in 1999, completed a psychiatry residency at UC Irvine, and finished a geropsychiatry fellowship at UC San Diego Medical Center in 2006. As CEO of Crownview Medical Group, he leads a multi-disciplinary practice covering psychopharmacology, addiction treatment, and child-through-geriatric psychiatric care, with the prescribing team coordinating medication-assisted treatment protocols alongside therapists such as Anne Cox at Crownview's C Avenue office when patients require concurrent psychotherapy and pharmacological management. Hospital affiliations with Sharp Coronado Hospital, Scripps Mercy Hospital San Diego, and Alvarado Hospital Medical Center provide inpatient-admission pathways for acute psychiatric stabilization that outpatient-only practices on Coronado Island cannot offer. Patients managing anxiety and PTSD symptoms through complementary channels benefit from the integrative model that includes referrals to providers such as Trinity Naturopathic when naturopathic protocols address sleep and cortisol regulation alongside psychiatric medication. Addiction-medicine protocols include buprenorphine induction, naltrexone maintenance, and structured relapse-prevention programming built on DSM-5 severity staging for alcohol and opioid use disorders.
