I’m Mackenzie, a Psychiatric Nurse Practitioner dedicated to helping children, adolescents, and adults find balance, clarity, and confidence through compassionate, evidence-based care. I believe mental health treatment should feel personal, not clinical.
I am a board-certified Psychiatric Nurse Practitioner in Massachusetts. I offer comprehensive treatment combining medication with lifestyle and behavioral interventions. I help adult clients manage conditions such as depression, anxiety, OCD, bipolar disorder, psychotic disorders and substance use disorder. I also specialize in helping women navigate the peri and postpartum periods. I use evidence-based treatments that consider the client’s biological, psychological, spiritual, and social needs.
I earned my Bachelor of Nursing from University of Connecticut (Go Huskies!) before moving to Boston to start my career in bedside nursing in 2019. After serving as an RN and Director of Nursing at a residential treatment center, I earned my PMHNP at Regis College to specialize in mental health. Since then, I’ve gained diverse experience providing cutting-edge ketamine therapy in outpatient clinics and managing complex cases in inpatient psychiatry. Now, I’m bringing that clinical expertise—along with post-graduate training in CBT—to my full-time private practice, where I provide comprehensive, compassionate care for patients navigating anxiety, depression, OCD and ADHD in the South Boston area.
I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP) with experience in both outpatient and inpatient settings, providing comprehensive mental health care across diverse populations. My background includes extensive work in behavioral health emergency settings, partial hospitalizations, IOP, recovery care, community psychiatric care. I also have experience supporting dually diagnosed patients with co-occurring medical conditions, giving me a broad perspective on the complex interplay between mental and physical health.
I earned my PMHNP degree from Post University and hold PMHNP licensure in both Massachusetts and New Hampshire. Throughout my career, I have remained committed to evidence-based care, while continuously seeking opportunities for professional development and growth in the mental health field.
