LEWISTON — Tri-County Mental Health Services announces the addition of two physicians and a nurse practitioner to the medical staff of the region’s largest mental health agency. Dr. James Krainin, Dr. William Berlingieri and Rebecca Chandler, PMH-NP, CS, will provide adult psychiatric services, including medication management, from various Tri-County Mental Health Services locations.

Dr. Berlingieri is located in the agency’s largest clinic, 1155 Lisbon St., Lewiston. He completed his residency and internship at SUNY Medical Center in Buffalo, N.Y., and has worked in the Portland area in private practice as well as with the Maine Medical Center Access Program.

Dr. Krainin and his wife, long-time fans of Maine and weekend visitors, moved to Naples in 2007 when he closed his private practice in Massachusetts.
