Dr. Nicole Renee Grinsell, PhD

Clinical Psychologist
San Francisco CA
In my private practice, I offer ketamine-assisted psychotherapy (KAP) as an adjunct to psychotherapy in partnership with an expert medical team, bringing experience across both private practice and acute care settings. As a clinical supervisor at The Integration Collective, I supervise doctoral-level associates and teach courses on integration as a psychological framework — one that can meet clients who feel stuck in conventional formats of care, and support early-career clinicians in offering integrative modalities ethically, safely, and meaningfully as they build their practices.
I support individuals integrating psychedelic and plant medicine experiences as part of a deeper therapeutic process. Many of the people I work with arrive carrying long-standing patterns that conventional approaches have touched but not fully reached — chronic self-pressure, identity confusion, shame, grief, or a quiet but persistent sense of disconnection from themselves. I support clients by creating a structured, emotionally safe space to clarify intentions before an experience, process what emerges during it, and translate insight into embodied, lasting change.
Clinical supervision for doctoral-level trainees (psychological associates registered in California) at The Integration Collective: www.theintegrationcollective.com My services are limited to psychotherapy and consultation within the scope of my psychology license. I do not administer, prescribe, recommend, or provide access to psychedelic or illicit substances.
