Dr. Ellen M. Riccio
DNP, PMHNP-BC, FNP-C · Psychiatric Nurse Practitioner
Dr. Ellen M. Riccio is double board-certified as a Psychiatric-Mental Health Nurse Practitioner and a Family Nurse Practitioner. She earned her Doctor of Nursing Practice from Walden University in August 2026, with a doctoral project on implementing structured safety planning in outpatient psychiatric care.
Most of her practice is by video, throughout Pennsylvania. This office is the other half of it: where she sees patients in person, in the same practice as Dr. McMullen rather than across a referral.
Before psychiatry she spent eighteen years in emergency medicine as a paramedic, flight nurse, and emergency nurse, and has years of experience with medication-assisted treatment for opioid use disorder. She served as clinical reviewer for The Alcoholic’s Survival Guide.
