ADHD therapists and psychiatrists in Lexington, MA

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.

Finding a provider can be challenging, overwhelming, and at times embarrassing. I have been in treatment for over 20 years, which prompted me to want to support other people like me. I am proficient in DBT as these skills have saved my life.

I am a woman in recovery, have been in psychiatric units, have a child with another woman, and attempted to end my life. I am healing everyday and you are part of that process.

I have worked with a variety of populations. I am passionate about working with other mental health professionals struggling with anxiety, depression, and trauma. I am honored to work with first responders (fire fighters, police, paramedics, doctors, etc). You are not alone. I understand the complex dynamics associated with seeking help.
