Gerald W. Grass, MD is an internationally known and respected physician. Prior to founding the Ketamine Research Institute, he served as Assistant Professor of Anesthesiology and Pain Medicine at Yale School of Medicine where the original ketamine infusion was first formulated in 1994 and also served as the Director of the Yale Pain Medicine Fellowship Program..

He began utilizing ketamine in treatment of chronic pain and depression in 1998 and has since pioneered the development of the RESTORE Infusion and has established Ketamine Infusion Training Program, the first international training program for physicians to rapidly alleviate treatment resistant mood disorders and intractable chronic pain.

The RESTORE Infusions were developed by Dr. Grass over a 20 year period as an improvement of the basic ketamine infusion. He has more direct patient clinical experience providing ketamine infusion therapy than any other physician in the United States, personally guiding hundreds of patients through the RESTORE experience. The ultimate goal was to make ketamine-based infusion therapy as effective and long lasting as possible.
