Obsessive-compulsive disorder therapists & psychiatrists in Greenbelt, MD

I understand that seeking help can feel overwhelming, especially when you’re struggling with anxiety, depression, trauma, or mood changes. As a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC), I provide compassionate, evidence-based care focused on helping you regain stability and move forward with confidence. I earned my MSN from Eastern Kentucky University and my Doctor of Nursing Practice (DNP) from Missouri State University. With experience in urgent psychiatric care, inpatient psychiatry, and outpatient treatment, I work with you to create a personalized plan that supports healing, resilience, and long-term well-being.

I work with adults and teens who feel overwhelmed, anxious, or emotionally drained. They may be struggling with anxiety, depression, ADHD, mood changes, trauma, or life stress and feel stuck despite trying to cope alone. Others seek clarity around symptoms or support during major life transitions. Children and adolescents may struggle with emotional regulation, attention, mood changes, or behavioral concerns. Often, individuals or parents want relief and a clear path forward with a provider who listens and helps them feel more balanced, focused, and hopeful.
