Marty Lajoie, Psy.D.

Dr. Marty Lajoie, Psy.D. is a licensed psychologist with over 10 years of experience working in the fields of addiction treatment, integrative mental health, and psychedelic-assisted therapies. He is the Founder, CEO, and Psychological Director of Holistic Psychology Inc. in Santa Rosa, California. He also serves as Psychological Supervisor for associate clinicians at Duffy’s Napa Valley, an integrative addiction treatment center; Associate Instructor for the Physiology and Pharmacology of Addictions course at Santa Rosa Junior College; and Director of Ketamine-Assisted Psychotherapy at Windows Health in Cotati (formerly Be the Change in Mental Health).

Dr. Lajoie earned both his Master’s and Doctorate degrees in Clinical Psychology from the California Institute of Integral Studies in San Francisco, where his dissertation research focused on psychedelic-assisted treatments for substance use disorders. He completed postdoctoral certification training with the Multidisciplinary Association for Psychedelic Sciences (MAPS) in MDMA-assisted psychotherapy for PTSD, as well as Ketamine-Assisted Psychotherapy training through Polaris Insight Center. His clinical training includes Integrative Mental Health, Psychedelic Harm Reduction Integration, Internal Family Systems (IFS), EMDR, Dialectical Behavior Therapy (DBT), Motivational Interviewing (MI), Brainspotting, and Nonviolent Communication (NVC), and Certified Neurodynamic Breathwork facilitation.

Prior to becoming a psychologist, Dr. Lajoie spent a decade providing trauma-informed residential care and counseling within a County of Sonoma child protective services shelter system. In the decade preceding that, he founded and led an electronic dance music event organization in the San Francisco Bay Area during the years surrounding the turn of the millennium (Happy Kids), where he designed and facilitated large-scale, multi-room experiential environments attended by hundreds to thousands of participants. These events were intentionally curated with attention to music sequencing, spatial design, sensory containment, and group flow, in contexts where participants were entering non-ordinary states of consciousness. This formative experience continues to inform his clinical approach to psychedelic-assisted psychotherapy, particularly his emphasis on set and setting, music curation, psychological safety, and the creation of supportive environments for transformative experiences.

In his personal life, Marty has been a consistently active member and advocate for addiction recovery support group communities since 2004. This, in particular, inspired him to further his education and professional development in the human helping fields and become the psychologist he is today.
