Hello! I am a Board-Certified Psychiatric Nurse Practitioner with a nursing career in psychiatry that spans over a decade. I have experience serving a diverse patient population in both inpatient and outpatient psychiatric settings.
I grew up in NYC and I received my Master's Degree in Nursing from University of Rochester.
I work with adults who feel overwhelmed, stuck, or not quite like themselves. Many of my patients come in with anxiety, depression, mood changes, sleep problems, or difficulty functioning the way they want to in daily life.
My approach is clear, structured, and collaborative. I do more than prescribe medication. I help you understand what may be contributing to your symptoms, what your options are, and what a realistic plan looks like moving forward.
If you’ve ever left an appointment feeling rushed or unsure about what to do next, my goal is to make sure that doesn’t happen here.
I’m a Psychiatric Mental Health Nurse Practitioner (PMHNP) with experience supporting adults navigating anxiety, stress, and burnout. A lot of the people I work with are high functioning on the outside but feel overwhelmed, mentally exhausted, or stuck in cycles of worry and overthinking. You can expect me to be calm, warm, and steady. I’m not going to rush you or pressure you to “perform” being okay. I’m interested in how your life actually works day to day: your responsibilities, culture, family roles, and the ways you’ve been coping, not just a checklist of symptoms. Many of the people I see are used to taking care of everyone else; in our work, it’s allowed to be your turn to be the one who gets supported.
I am dual board-certified as a Psychiatric Mental Health Nurse Practitioner and Family Nurse Practitioner. After several years of clinical practice, I earned my doctoral degree in 2021. My experience spans both behavioral and family health settings, including hospital-based behavioral health units, partial hospitalization programs, and intensive outpatient care.
I specialize in the diagnosis and treatment of a wide range of mental health conditions, including ADHD, depression, anxiety, bipolar disorder, OCD, panic disorder, and PTSD. My approach is grounded in evidence-based practice and emphasizes holistic, collaborative care.
Together, we will develop a personalized treatment plan tailored to your unique needs, goals, and values through a shared decision-making process.
I am committed to creating a supportive, nonjudgmental environment and to addressing disparities in mental health care. If you’re struggling, you don’t have to go through it alone. I’m here to support you with compassion, expertise, and care.
My name is Heather, and I prefer people refer to me as Heather, not Dr. Muxworthy. I have worked as a Psych RN, CNS, and NP for the past 35 years. My passion has been to work with people with bipolar disorder, major depression, anxiety disorders. I have a subspecialty in Personality Disorder. I am well versed in Dialectical Behavior Therapy, as well as Cognitive Therapy and other modalities. I am a therapist at heart and also can prescribe psychotropic medications.
