Find out more about ketamine-assisted therapy
Acheron is a psychiatrist-led, multi-therapist practice offering ketamine-assisted psychotherapy (individual and group). Under the supervision of Harvard-trained psychiatrist Daniel Zimmerman, M.D., your ketamine-assisted treatment at Acheron is a healing experience for mind, body, and soul.
At low doses, ketamine-assisted therapy helps relax psychological defenses, enhances emotional processing, and makes therapy more productive.
At higher doses, it can induce a psychedelic experience – a rare, profound window for deep healing, emotional exploration, and personal growth. With thorough preparation, a supportive environment, and a trusted therapeutic relationship, ketamine therapy can unlock one of the most powerful forces in mental health: your own internal healing wisdom.
We honor this sacred medicine by weaving it with deep psychotherapy, mindful medication management, and healing community events that nourish your whole being. Research shows ketamine treatment can be particularly effective when traditional treatments have failed.

It can be hard to tell if what you’re feeling means you have a mood disorder. A therapist can help you get to the core of what you’re experiencing, and make a diagnosis. Your therapist will interview you, talk about the symptoms you’ve been experiencing and for how long, and can also help identify or rule out medical causes.
A qualified therapist will help you develop an individual treatment plan that takes your unique needs into consideration. The treatment for a mood disorder may include:
