I am a board-certified Psychiatric Mental Health Nurse Practitioner with extensive experience across inpatient psychiatry, crisis stabilization, substance use treatment, residential care, intensive outpatient programs, and outpatient medication management. My background has given me the opportunity to work with individuals facing depression, anxiety, bipolar disorder, PTSD, ADHD, substance use concerns, mood instability, sleep problems, and life transitions.
Clients often describe my style as calm, direct, supportive, and easy to talk to. I believe mental health care should feel collaborative, respectful, and practical. My goal is to help clients better understand what they are experiencing, explore treatment options, and build a plan that supports real improvement in daily life.
I have a strong interest in treatment-resistant depression, interventional psychiatry, and evidence-based medication management, while also recognizing that each person’s story, goals, and values matter just as much as symptoms or diagnoses.
