Temenos Center Staff

Temenos was born on the shores of Tomales Bay in Marin County, California at the Marconi Conference Center in June 2018 where the four founders (Jim, Carl, Christina and Jessica) came together in the CPTR (Certificate in Psychedelic Therapies & Research) program through CIIS (California Institute of Integral Studies), and shared our visions and dreams of bringing psychedelic-assisted psychotherapy to our community.


All of the Temenos staff is trained in ketamine-assisted psychotherapy.  We approach this work with humility, out of deep respect for the medicine and for the inner healing potential of the clients we serve.

Jessica McIninch, PsyD

Carl Spitzer, MD

I use a depth-oriented approach in the treatment of complex trauma, depression and psychospiritual issues. For the past 20 years, my clinical work has combined neuropsychological principles, contemplative practice, and psychodynamic modalities. I am passionate about the use of psychedelic-assisted therapy as a potential catalyst for personal and collective healing.

More about Jessica here.

I have a keen interest in how the Western medical model and the transpersonal realm can inform each other for psychological wholeness. We each have an inner healing wisdom that knows the path to our own well-being; it is the job of the practitioner to assist the client in uncovering and reclaiming their innate power. Temenos is the sacred space for that rediscovery to occur.

Felicia Matto-Shepard, MFT

As a lifelong student of art making, dreamwork, and psycho-spiritual development, I see creativity as a fundamental source of meaning and inspiration. I am a Certified Jungian Analyst. I offer integration workshops and sessions using process art.  


I hold a bachelor’s degree from Harvard and a medical doctorate from Perelman School of Medicine at the University of Pennsylvania. The psychedelic renaissance lured me out of 15-year career as a trauma surgeon to pursue a master’s in social work. Now this solid education allows me to practice ketamine-assisted psychotherapy and provide deeper healing than surgery or traditional medicine. I feel blessed to work at Temenos, helping people grow beyond their trauma to reconnect with their innate joy and radiance.

You are on a journey.  I offer a safe container for you to explore where that journey takes you.  I adopt a depth approach to psychotherapy that starts from a place of compassion and respect.  I am influenced by spiritual teachings as well as my own study of the subtle body and non-ordinary states of consciousness. Work with me begins and ends with what you need. I am excited to be with you on this step of the path . Learn more about me at www.allisonzamani.com

CM Temenos Bio PIc.jpg

Colette Mercier, LMFT

As a therapist, I believe in your innate ability to heal. I most often work with trauma, anxiety, and postpartum depression. I draw on somatic therapy, hakomi, gestalt and relational approaches. Prior to being a therapist, I delivered babies. In each delivery, I learned about human resilience. To contend with pain and come out stronger in the end is a process birth and therapy have in common.  I see our struggles as a pathway to greater love, both for yourself and those around us.

Jean Vierra, MD

I respect the power of the Inner Healing Intelligence that exists in each one of us.  I love accompanying clients on their healing journeys and being with them through the intensity, transition and transformation. I trained at UCSF Medical School and University of Washington in Obstetrics and Gynecology. I have been working throughout my career with women and families during times of major transition.  I discovered the power of Ketamine to accelerate the healing process while on my own healing path. These experiences drew me to complete the Hakomi training, Ketamine training and the Certificate in Psychedelic -Assisted Therapies and Research at The California Institute of Integral Studies.  I look forward to assisting you in achieving the best possible outcome this medicine can bring to your healing.
