Travis Hyke, PhD | Clinical Supervisor
Dr. Hyke strives to be collaborative, empowering, and candid in all his therapeutic relationships. He believes working with someone is about creating a safe space to learn how to reconnect with their authentic self, explore dynamics of their life and relationships, and practice new ways of being that restore balance, peace, and fulfillment in their life.
In addition to direct patient care, he also provides supervision and training for practicum, internship, and post-doctoral level psychology students.
He completed a postdoctoral fellowship, externships and internships at Sharp Mesa Vista inpatient and outpatient programs, El Camino Hospital, Gronowski Center Community Mental Health Clinic, and as a college student substance use and conduct counselor at Notre Dame de Namur University. He also has experience working in dual diagnosis centers serving patients with complex clinical presentations and experience working for UC San Diego’s outpatient psychiatry program.
Dr. Hyke earned his doctorate in clinical psychology from Palo Alto University in Northern California. His research has emphasized the identification and treatment of emerging adults and adolescents with substance use disorders. He has been published in these areas of research as a contributing author in The Journal of the American Medical Association, The California Psychologist, The Journal of Primary Prevention, and Therapeutic Drug Monitoring and Paradigm Magazine. He has also had media spots on NBC news and KUSI Channel 6 news in San Diego to discuss overdose awareness, the opioid epidemic and alcohol addiction.
A Californian at heart who wants to be in the ocean and in the mountains as much as humanly possible, Dr. Hyke believes that connection with oneself, the people around you, and the natural environment are crucial to a fulfilling and values-driven life. Born and raised in southern California, he has lived in Los Angeles, Santa Barbara, San Francisco and San Diego. He loves spending time with close friends and family, surfing, backpacking, snowboarding and playing volleyball.

Dr. Jiseung Yoon, MD MPH | Medical Doctor
His clinical practice emphasizes the integrated treatment of co-occurring substance use and mental health disorders, recognizing that sustained recovery requires addressing both conditions in parallel. Dr. Yoon works closely with patients managing depression, anxiety, trauma-related disorders, and other psychiatric conditions alongside addiction, coordinating pharmacologic and behavioral interventions to support whole-person healing.
Drawing on his preventive medicine background, Dr. Yoon takes a whole-person approach that extends beyond symptom management to the foundations of long-term wellness. He partners with patients on sustainable lifestyle changes — sleep, nutrition, physical activity, stress management, and mindfulness practices — understanding that these habits are not adjuncts to recovery but central to it.
Dr. Yoon is committed to delivering evidence-based, compassionate care to individuals and families affected by addiction and mental illness.
