Obsessive-compulsive disorder therapists & psychiatrists in Danbury, CT

I understand that the decision to seek help for mental health needs can be a nerve-racking and scary process. When it comes to patient care, I am most passionate about the preservation of dignity and making my patients feel seen. I meet fear or nervousness with acceptance, encouragement, and knowledge.

If medication has felt like guesswork, it doesn't have to.

I'm a board-certified Psychiatric-Mental Health Nurse Practitioner (PMHNP-BC),

licensed in Connecticut, and I work with adults by secure video across the

state, in English and in French.

I prescribe to the minimum effective dose. We start carefully, change one thing

at a time, and judge the result by how you actually feel and function, not only

by a symptom score. You'll always know why a medication is on your list, what

it's expected to do, and when we'll reassess it.

Mental wellness isn't just the absence of symptoms. It's getting your life back.

I work with adults navigating anxiety, career and life transitions, grief, and questions of identity and purpose — whether that's a 20-something rethinking their path, someone reassessing a career after years in it, or an older adult navigating retirement, caregiving, or the shifts that come with later life. My approach is collaborative and grounded: you'll leave sessions with more clarity than you came in with, not just more to think about.

I came to this work after a first career in banking. I understand the pressure, identity, and burnout that come with corporate life firsthand — and what it takes to actually rebuild around what matters to you, whatever stage of life or career you're in. I hold a Master's in Mental Health Counseling from Yeshiva University.

Taking that first step toward mental health care can feel like a lot, and I want to make it easier. I offer telehealth appointments in Connecticut, and I bring over three years of community mental health experience to every session. Whether you are navigating anxiety, working through depression, or healing from trauma, I meet you where you are and help you build a plan that fits your actual life. My approach is warm, practical, and focused on what works. I am here to help you move forward, one step at a time.

At the heart of my practice is the belief that patients deserve to be heard. I am committed to providing thoughtful, collaborative mental health care where patients feel supported, respected and empowered throughout their journey toward mental wellness. I provide psychiatric evaluations, medication management, supportive therapy and evidence-based interventions for conditions including anxiety, depression, ADHD, mood disorders, trauma related concerns and life stressors. I have ten years of experience working in the mental health field in inpatient, outpatient residential, long-term care, tele-health and community mental health settings.
