Altum Psychiatric Services

Expand your concept of what is possible.

About Us

Altum Psychiatric Services is dedicated to helping people uncover, understand and leverage their unique neurobiology to improve psychological, physical, and social well-being.This is not meaningless neuroscience. We are driven by the need for our society to augment and expand it’s concept of mental health treatment. Early acknowledgement, validation, thorough assessment and adaptable leading-edge interventions are our core processes. Altum Psych is committed to reforming and expanding the definition of acceptable care spaces and modalities for clinicians and patients alike. In solidarity with families and colleagues nationwide, we vow to normalize conversations about suffering and how to relieve it appropriately. Stigma has created severe consequences for all of us at a cost too high for children, adults, families and society. Change begins here.

Altum has been honored this past 2 years to serve and learn from each and every client. Our lease is expiring and we’ve decided not to renew. It’s been beyond phenomenal, and now it’s time for a break. Our last day will be September 30th, 2019. We will reach out to our routine psych clients to ensure a smooth transition process back to primary care. I’m afraid we cannot accept new general psych clients at this time. We have limited capacity for IV ketamine courses between now and 9/30. I am happy to report that private psychiatric services and IV ketamine will be available in Plymouth within weeks of our closing with clinicians we trust. Their presence gives us ‘permission’ to rest.

With Gratitude,


Ketamine Therapy

In addition to our general psychiatric services we offer IV ketamine therapy and ketamine-assisted psychotherapy. IV ketamine is a revolutionary therapeutic approach to treating depression and anxiety disorders. Ketamine therapy is significantly more effective than other pharmaceuticals, is very safe, has few if any side effects, and is often life-changing.

Call 1-888-268-5231 for an appointment at Altum Psych in Plymouth, New Hampshire.
