Introduction

With over 35 years of experience in healthcare—including service in the U.S. Army and clinical roles at Boston Children’s Hospital—I specialize in supporting individuals navigating mental health and substance use challenges. I'm a Certified Family Nurse Practitioner and an Addictions Registered Nurse – Advanced Practice, with a degree from the Massachusetts College of Pharmacy and Health Sciences. My care philosophy is holistic and evidence-based. I work with each individual to integrate key lifestyle factors—like nutrition, physical activity, sleep, and work-life balance—alongside medication management when appropriate. I also draw from a range of therapeutic approaches, including Dialectical Behavior Therapy (DBT) techniques, the 12-Step model, motivational interviewing, and mindfulness practices. Above all, I’m committed to helping you build a healthier, more connected life—one grounded in resilience, self-awareness, and meaningful change.
