Dr. Dianne Sterling in Encinitas's Cardiff-by-the-Sea has practiced clinical psychology since completing fellowship training in the Harvard and Boston University Medical School systems, earning her Psy.D. from William James College in 1989 under California license PSY20544. Mindfulness-based cognitive therapy protocols for depression and trauma integrate Eastern contemplative practice with Western clinical methodology, a mind-body therapeutic model that complements the manual therapy techniques at The How Clinic in Encinitas. Individual and couples treatment for ADHD, PTSD, anxiety, and treatment-resistant depression operates from the Cardiff Executive Center on Birmingham Drive near San Elijo Lagoon. Active clinical research in psychedelic-assisted psychotherapy through atai Life Sciences and Ketamine Assisted Psychotherapy certification through Kadima Neuropsychiatry Institute position the practice at the clinical frontier of treatment-resistant mood disorders, complementing the integrative medical model at Kind Health Group. The Birmingham Drive office serves Cardiff-by-the-Sea and greater Encinitas with both in-person and telehealth modalities. Highest-complexity engagements involve multi-session Ketamine Assisted Psychotherapy protocols combining sub-anesthetic ketamine administration with structured preparation, dosing, and integration psychotherapy sessions for treatment-resistant PTSD.
