Obsessive-compulsive disorder therapists & psychiatrists in Williamsport, MD

I believe that optimal mental health is achieved through an ongoing, multi-pronged approach. As a psychiatric nurse practitioner I am well trained in the art and science of prescribing medications to improve mental health symptoms. I also encourage adjunctive treatment modalities such as CBT. Empowering patients to care for themselves is part of my goal. I embrace opportunities to help my patients gain greater personal insight, because when you can see yourself, you can change yourself.

You may look like you’re doing fine on the outside while internally feeling anxious, overwhelmed, disconnected, or stuck. Maybe you’re successful in your career but struggling with relationships, perfectionism, self-doubt, or the pressure to keep everything together. Maybe you’re navigating a major life transition, trying to understand yourself more deeply, or noticing that old patterns are showing up in your relationships. I offer an individualized approach that draws from nearly 15 years of clinical experience with evidence based treatment work. My work incorporates ACT, CBT, psychodynamic therapy, and Gottman couples work.

Provider with caring, compassionate, and empathetic attitude in responding to the needs of clients. I work with adults seeking support with their health and path forward.
