I earned my BSN from Skidmore College, my MSN from Fairfield University, and I also completed training in Behavioral Sleep Medicine and adult sleep disorders at the University of Pennsylvania.

If you are feeling overwhelmed by anxiety, stuck in patterns of trauma, or exhausted by PTSD, healing is within reach. I am a compassionate psychiatrist whose practice is informed by a social-work lens. This means I look at the big picture—how social, environmental, and biological factors impact your mental health. My goal is to guide you from a place of survival to thriving. I provide careful diagnostic assessments and tailored treatment plans that respect your preferences, helping you safely process the past and reclaim control over your future wellbeing.

I am passionate about helping clients cultivate greater balance, vitality, and overall well-being in their lives. I have experience working with individuals facing a wide range of mental health concerns, including depression, anxiety, trauma, bipolar disorder, OCD, ADHD, disordered eating, substance use disorders, and insomnia.

I am a board-certified adult psychiatrist with more than 22 years of experience providing compassionate, evidence-based psychiatric care in inpatient, outpatient, consultation-liaison, and telepsychiatry settings.

Throughout my career, I have helped adults struggling with depression, anxiety, bipolar disorder, panic disorder, trauma-related conditions, somatic symptom disorders, and other complex psychiatric illnesses. I also specialize in the treatment of substance use disorders, including medication-assisted treatment with buprenorphine (Suboxone) for opioid use disorder.

My philosophy is simple: every patient is unique, and treatment should be personalized. I combine comprehensive psychiatric evaluation, medication management, supportive psychotherapy, lifestyle and nutritional counseling, and when appropriate, pharmacogenomic (genetic) testing to help identify medications that may be most effective while minimizing side effects.

I believe mental health is closely connected to physical health. My whole-person approach addresses emotional well-being, sleep, nutrition, exercise, stress management, and healthy lifestyle habits to promote lasting recovery and resilience.
