Psychiatric Mental Health Nurse Practitioner
Erin Lewis, PMHNP-BC
Erin Lewis, PMHNP-BC, is a board-certified Psychiatric Mental Health Nurse Practitioner dedicated to providing compassionate, patient-centered mental health care. She was inducted into Sigma Theta Tau International Honor Society for Nursing and earned her Bachelor of Science in Nursing (BSN) with honors from Holy Family University in 2006. From there, she spent many years caring for patients in cardiac and oncology settings as a registered nurse.
Throughout her nursing career, Erin discovered that some of the most meaningful aspects of patient care came through listening, building relationships, and helping individuals navigate life's challenges. Inspired by these experiences, she pursued advanced training in psychiatric care and earned her Psychiatric Mental Health Nurse Practitioner degree from Walden University in 2024.
Erin believes that effective mental health treatment begins with understanding each person's unique experiences, goals, and circumstances. She is committed to developing individualized treatment plans that empower patients to take an active role in their care while receiving evidence-based support tailored to their needs.
Erin has special interest in treating adults aged 18 and older who are experiencing a wide range of mood and anxiety-related concerns. By combining a holistic perspective with evidence-based psychiatric care, Erin helps her patients build resilience, improve their quality of life, and work toward lasting emotional wellness.
