Irina Linetskaya, MD

Irina is a board certified Internal Medicine physician and LGBTQ+ health and HIV specialist whose integrative medicine practice, Contemplative Medicine, focuses at the intersection of physical illness, emotional trauma, and spirituality. Irina has supplemented her rigorous medical education with training in Ketamine-Assisted Psychotherapy with Drs. Phil Wolfson and Bessel van der Kolk, Internal Family Systems Therapy (Level 1), Core Energetics (a somatic psychotherapy modality), and over a decade of Vipassana meditation practice.

Irina grew up in the former Soviet Union in a family deeply burdened with mental illness, violence, and post-Holocaust trauma. Her own healing journey via somatic trauma therapy, Vipassana meditation, and psychedelic-assisted therapy in the US and the Peruvian Amazon opened her eyes to the complex nature of health and illness - complexity reaching far beyond her Western medical education. Irina has come to regard most illness as the body’s attempt to communicate, in an increasingly insistent voice, deep-seated imbalances within. Her clinical approach is one of deep listening and root-level healing of the body, mind, spirit, and ancestry. Irina speaks multiple languages and is passionate about bringing multi-dimensional, tailored healing to individuals, groups, and communities, with a primary focus on populations deeply impacted by systemic violence, poverty, and ancestral trauma.


Irina is an avid hiker, mushroom forager, and adventurer who splits her time between the Hudson Valley and Brooklyn.

Daniel J. Zimmerman, M.D.

Dan is a board-certified psychiatrist in private practice in New York City.  

Dan completed his residency at MGH/McLean in Boston, where he received the Hackett Award for academic research.  He subsequently completed a public psychiatry fellowship at Bellevue Hospital.  

As a former English literature major who gravitates toward subjectivist and hermeneutical understandings of the mind, Dan is a “throwback” to the days when psychiatrists were versed in psychotherapeutic theory and methods, in addition to psychopharmacology.  Upon discovering and training in ketamine-assisted psychotherapy since last year, Dan has been most thrilled to work with a medicine that can facilitate and enhance the psychotherapy process.

Dan recently opened a group psychiatry practice in the city called Acheron, where he trains therapists and treats patients using conventional and psychedelic psychiatry methods.  

Dan lives in Park Slope with his spouse Amanda, a neuropsychology professor at Cornell Neurosurgery, and his two young sons, Jonah and Gabriel.
