Obsessive-compulsive disorder therapists & psychiatrists in Lexington, MA

I love working with clients who are reflective, open to self-exploration and ready to challenge long-standing beliefs about themselves. I help adults build confidence, improve emotional regulation, strengthen relationships, and develop healthier coping strategies for managing stress, anxiety, or trauma-related symptoms. I believe therapy is a collaborative process where clients gain practical tools to interrupt negative thought cycles, process difficult experiences, and move toward a more balanced, self-compassionate way of living. This helps clients experience greater clarity, stronger boundaries, and improved self-worth.

Life can look “fine” on the outside while still feeling overwhelming internally. Hi! I'm Mary and I am a Doctorally prepared nurse practitioner, mom and first responder wife. I have over nine years of experience supporting individuals through life’s most vulnerable moments and as a dual board-certified Psychiatric Mental Health and Family Nurse Practitioner, I take a thoughtful, whole-person approach to care.

I work with adults experiencing anxiety, depression, ADHD, mood symptoms, and cognitive changes, often during periods of high stress or hormonal transition. My approach looks at the full picture including mental health, sleep, metabolism, and overall well-being to develop personalized treatment plans. I combine medication management with practical strategies to help you feel more balanced, focused, and in control.

As a licensed mental health counselor, I believe that mental well-being is foundational to living a fulfilling and connected life. Taking the step to begin therapy can be challenging, and I commend you for making that choice. Over the course of my career in college and community mental health, I’ve had the privilege of helping individuals navigate substance use, addiction, anxiety, grief, trauma, life transitions, and challenges with motivation. My goal is to create a compassionate, judgment-free environment where growth and healing can take root.

We all need connection, community, and the ability to be our authentic selves in order to thrive. Many of us are not provided these attachment needs in childhood, and we grow into adulthood burdened by this wounding, unsure of how to relate safely and from a place of wholeness. If you struggle to align your inner and outer worlds, find yourself repeating difficult relational patterns, or feel as if your authentic self must remain hidden, I would love to work with you. I am particularly interested in supporting the health of queer families and cooperatives.
