Bipolar disorder therapists & psychiatrists in Lexington, MA

I am a behavioral health clinician specializing in mood disorders, anxiety, trauma‐related conditions, and the emotional complexities that arise alongside chronic medical and cognitive challenges. My practice blends clinical precision with a calm, supportive presence, helping individuals feel understood, grounded, and empowered throughout their care.

Don’t just treat symptoms—but listen for the story behind them.

Integration of medical, psychiatric, and psychosocial threads into a coherent and dignified plan.

I work with adolescents and adults navigating addiction across the full spectrum, including alcohol and other substances, compulsive or process-based behaviors, early recovery, relapse vulnerability, long-term recovery, and transitions out of inpatient or higher levels of care. I also support clients experiencing co-occurring challenges such as anxiety, trauma, grief, depression, and major life transitions.

I have been working in the behavioral health field since 2015, with experience in addiction and mental health treatment across a range of settings and levels of care. I hold a Master of Social Work from Simmons University and am LCSW-eligible. I work with adolescents (13+) and adults, and I welcome clients at all stages of readiness, including those who feel unsure, ambivalent, or overwhelmed by change.

At the core of my work is the belief that addiction is rarely just about the behavior itself. It often reflects deeper emotional, relational, and stress-based patterns that deserve understanding rather than judgment. I place strong value on helping clients build internal resources while also connecting them to supportive services and external supports when additional structure or care would be helpful.

We grow at our own pace, but it is my experience that with counseling support, personal evolution can happen more quickly. As a Clinical Psychologist, Licensed Independent Clinical Social Worker, and Life Coach, my background is Cognitive Behavioral Therapy with an emphasis on mindfulness, behavioral changes, emotional regulation, and finding solutions.
