Peter “Pete” DalPra, LADC and LCS, has been working in the field of addiction treatment since 1993, serving as a counselor, an outreach worker, a clinical supervisor, and a program director. As a leader and advocate for treatment in New Hampshire, Pete has also served on government commissions, on the boards of associations, and as a member of behavioral health coalitions.

Pete began his career after he went through addiction treatment thirty years ago. He recalls, “with a couple of the staff members, you could see in their eyes they really cared about us; that was a calling.” He decided to give back by becoming an addiction counselor, and he quickly knew it was where he belonged.

Pete has an associate degree in human services, with a major in alcohol and drug abuse counseling, from New Hampshire Technical Institute where he now teaches as adjunct faculty. After earning his degree, Pete worked with Nashua Public Health Department doing street outreach to clients who were HIV positive. He also worked as a counselor for adults and adolescents at Seaborne Hospital.

Pete is experienced with providing care for a range of people and has worked across the continuum of care. He has served as a HIV/AIDS chemical dependency case manager with New Hampshire Division of Alcohol and Drug Abuse Prevention and Recovery and as an alcohol and drug counselor at a teen outpatient program. At Serenity Place in Manchester from 2002-2009, he filled the roles of clinical director and interim executive director. From there while working in his private practice he was recruited to be the program director for the Phoenix House in Franklin NH and soon was given the expanded role of overseeing the Phoenix Houses in Northfield and Dublin NH. As director, Pete focused much of his efforts on building up and training staff assisting them towards licensure.

In addition to his work over the past 28 years , Pete has served as 2-time president of the New Hampshire Association of Alcoholism and Drug Abuse Counselors (NHADACA) and as such served on the board of directors for NAADAC, the Association of Addiction Professionals. Pete was State certified to teach impaired driver intervention programs and was appointed by Governor John Lynch to a commission that examined DWI education and intervention programs and worked on DWI legislation. Governors’ Lynch and Hassan appointed him to the New Hampshire Board of Licensing for Alcohol and Other Drug Use Professionals where he served for six years.

Pete enjoys spending time with his 7 grandchildren, has been playing Bass Guitar for 50 years, was involved with Little League Baseball for 30 years and likes playing golf with people who are better than he is so they can play down to his level!
