Altum Psychiatric Services

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. We are driven by the need to improve access to high quality clinical mental and behavioral health care for all ages. 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.

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.
