Like many, I live in and love the state of Colorado. Any chance I get I'm out exploring the outdoors. It provides balance in my personal and professional life.

As a dual-certified Family and Psychiatric Nurse Practitioner I share my interests with clients I see.

When I was working full-time as a Family Nurse Practitioner I saw an unmet need in clients finding a balance in their physical and mental health. I decided to return to school to strengthen my knowledge in psychiatric mental health care.

For the past five years my focus has included seeing clients with substance dependence, MAT treatment, ADHD, Major Depressive Disorder, Bipolar Disorder and Schizophrenia. I especially enjoy the 1:1 experience via telehealth seeing clients in the comforts of their own home.

My experience and work in correctional and forensic settings have enhanced my adaptability, cultural sensitivity, and skills in managing complex psychiatric presentations. My wealth of clinical expertise, leadership, and a profound dedication to serving individuals with dignity and respect. My mission is to provide safe, effective, and empathetic care while advocating for mental health awareness and reduce stigmas.

Born and raised in Brooklyn, New York, I completed my medical training at NYIT College of Osteopathic Medicine. As an osteopathic physician, I practice with a holistic lens—integrating mind, body, and spirit—and value personalized, relational, and evidence-based care. I completed my psychiatric residency at St. Elizabeths Hospital in Washington, DC, a forensic psychiatric hospital often referred to as “the ICU of psychiatry” for its work with individuals facing chronic, treatment-resistant conditions. After residency, I spent three years in outpatient psychiatry within large corporate settings and ultimately transitioned to an eating-disorder hospital, seeking work aligned with depth, integrity, and true patient-centered care.

As a first-generation Ukrainian Jew and a native Russian speaker, I hold lived experience with immigration, intergenerational trauma, and cultural stigma surrounding mental health. This background informs my compassion, humility, and commitment to meeting patients where they are.

Hi, I’m Erin McMahon, a board-certified psychiatric mental health nurse practitioner (DNP, PMHNP-BC) providing telehealth care across Colorado. I focus on outpatient medication management for adults navigating anxiety, depression and other mood disorders, bipolar disorder, schizophrenia spectrum disorders, and women’s mental health.

Before becoming a psychiatric NP, I spent more than a decade as a nurse in emergency and critical care, along with inpatient psychiatric experience — so I bring a steady, grounded presence, even when things feel complicated. My care is rooted in shared decision making: you’re an active partner in your treatment, not just a recipient of it. I take time to understand not only your symptoms, but your history, your life, and what matters most to you before we talk about next steps. I’m trauma-aware, identity-affirming, and comfortable with complexity, and I offer culturally humble care to clients of all identities and backgrounds, including LGBTQIA+ individuals.

I have a particular soft spot for high achievers, eldest daughters, and the people who quietly hold everything together for everyone else. Your first visit is about getting to know you — not rushing to a diagnosis or a prescription. We’ll talk about what brought you in and what you’re hoping for, and my goal is for you to leave feeling genuinely listened to, with a clearer sense of what working together might look like. I’m not your typical provider, and I tend to attract clients who aren’t looking for typical care.

I am a dual-certified Psychiatric Mental Health Nurse Practitioner (PMHNP) and Acute Care Nurse Practitioner (ACNP) committed to providing compassionate, evidence-based mental health care for adults. My approach integrates current research, individualized treatment planning, and collaborative decision-making to support each patient’s unique goals and needs.

I provide comprehensive psychiatric evaluation and treatment, including medication management using evidence-based practices. I work with adults experiencing depression, anxiety, bipolar disorder, trauma-related conditions, and other mood disorders. My goal is to create a supportive and nonjudgmental environment where patients feel heard, respected, and actively involved in their care.

I believe that effective treatment is built on a strong therapeutic relationship. By working together, we will develop a personalized plan that promotes symptom management, resilience, and overall well-being. I am committed to helping you feel empowered in your mental health journey and to ensuring that your voice remains central in the treatment process

I am a double board-certified Psychiatric–Mental Health Nurse Practitioner with over 20 years of experience across the continuum of psychiatric care, including acute psychiatric emergencies, inpatient and outpatient psychiatry, geriatric mental health, intellectual and developmental disability services, and healthcare management. I hold a Master of Science in Nursing (MSN) and am currently completing my Doctorate, reflecting my ongoing commitment to clinical excellence, evidence-based practice, and lifelong learning.

Throughout my career, I have worked with individuals and families navigating a wide range of psychiatric conditions, from situational anxiety and depression to severe and persistent mental illness. My clinical experience includes extensive work with schizophrenia and psychotic disorders, bipolar disorder, major depressive disorder, generalized anxiety disorder, panic disorder, obsessive–compulsive disorder (OCD), trauma-related conditions, and mood instability across the lifespan. I am particularly experienced in caring for geriatric patients, individuals with intellectual and developmental disabilities, and patients with complex medication regimens requiring careful evaluation, simplification, and long-term stabilization.

I also work closely with college-aged patients and adults who are navigating academic pressure, career transitions, family dynamics, identity development, and the cumulative stressors that can emerge during periods of high responsibility or change. Many of my patients are high-functioning individuals who appear “put together” on the outside but struggle internally with anxiety, rumination, intrusive thoughts, emotional dysregulation, or burnout. Others are managing chronic psychiatric illness while striving to maintain independence, relationships, and quality of life.
