I am a board-certified Psychiatric Nurse Practitioner with a passion for integrative, whole-person care.

I am a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with training in adult outpatient psychiatry and telehealth. My background includes psychiatric evaluation and medication management for adults with anxiety, depression, mood-related concerns, ADHD, trauma-related symptoms, sleep difficulties, and stress or burnout. I take a supportive, collaborative approach focused on clear communication and shared decision-making. Evening appointments are available.

Prior to becoming a psychotherapist I was exactly where you are now reaching out for support. You don't have to go through this alone. I have a Master's Degree in Holistic Counseling and I am also a licensed Mental Health Counselor with 20 years experience working with anxiety, depression, loss and trauma. Therapy helped me to understand myself and cope with my situation. It also led me to my education which, taught me that seeing yourself as a whole gives you more options to choose from when things go wrong. By combining the two I can better support what you most need so you can move forward with purpose and see that there is life beyond coping.

Struggling with insomnia, anxiety, or depression?

I use a little known approach called CBT-I for Insomnia treatment. Together, we'll build practical skills to help you sleep better, break unhelpful patterns, and move toward a life that feels more meaningful. But you don't need to have insomnia to see me. I'm a goal-focused therapist who believes lasting change happens one step at a time. Progress isn't about perfection—it's about continuing to move forward, one step at a time.

I am a board-certified psychiatrist committed to delivering compassionate, evidence-based, and person‐centered care to individuals experiencing a wide range of mental health challenges. My training includes a general psychiatry residency in New Jersey and an advanced Addiction Psychiatry/NIDA‐T32 Research Fellowship at Columbia University in New York City, where I received specialized experience in the treatment of substance use disorders, comorbidity, and academic research.

Twenty-five years in this field — across inpatient units, outpatient programs, and private practice — means I've sat with people in virtually every kind of difficulty. That depth of experience shapes how I show up: grounded, unhurried, and genuinely confident that change is possible, even when it doesn't feel that way yet.

I work with adults navigating anxiety, depression, trauma, substance use, ADD/ADHD, stress, and major life transitions. I bring both clinical rigor and real human warmth to the work — because neither alone is enough.

I trained at Hunter College School of Social Work and have built my practice around one belief: that insight without practical tools doesn't get people very far, and tools without insight don't stick. We'll work on both.

I’m a Licensed Clinical Social Worker (LCSW) in private practice with an extensive background in social work across diverse settings. My work is grounded in compassion, ethical practice, and a deep respect for each person’s unique story.

I earned my Master of Social Work (MSW) from Sacred Heart University where I received comprehensive training in clinical practice and evidence-based interventions. I have experience working with adults and older adults navigating a wide range of concerns, including dementia, anxiety, burnout, stress, and the everyday ups and downs of life. My background has equipped me to support clients with both complex clinical needs and the challenges that naturally arise across different life stages.

I've spent my career working with people who are dealing with some of life's hardest circumstances — trauma, addiction, domestic violence, grief, chronic illness, and the day-to-day weight of anxiety and depression that doesn't announce itself. I bring both clinical training and real compassion to that work.

As a Black female therapist, I'm especially attuned to the cultural context that shapes how we experience stress, seek help, and heal. I specialize in anxiety, depression, PTSD, trauma, BPD, domestic violence, and substance use, and I work with adolescents, adults, and seniors across Connecticut.

My approach is practical and trauma-informed — I meet you where you are, not where I think you should be. You've already taken a step by being here. We can take the next ones together.

I am a Licensed Professional Counselor and Nationally Certified Counselor. If someone in your life makes you feel guilty, confused, unloved, or stressed, I'm here to support you.

I work with courageous people healing from the trauma of toxic relationships and I assist them in developing assertive communication skills & unlocking the power behind setting healthy boundaries. Together, we can reclaim your self-worth and build a life filled with empowerment and resilience.

Finding a therapist who genuinely understands your background, not just your diagnosis, can make the difference between therapy that feels like going through the motions and therapy that actually moves you.

I'm a bilingual Licensed Clinical Social Worker (LCSW), Certified Clinical Trauma Professional (CCTP), and Certified in Dialectical Behavior Therapy (C-DBT), fluent in English and Hebrew. I'm also a Doctoral Candidate pursuing my DSW. I work with adolescents and adults navigating trauma and PTSD, anxiety, depression, grief, relationship challenges, identity, emotional regulation, and major life transitions.

Before private practice, much of my clinical work took place in crisis response, hospital-based care, community mental health, and other high-stress environments. That experience taught me how to sit with difficult things without becoming intimidated by them, while also recognizing that people are far more than the hardest things that have happened to them.

As a therapist, I'm warm, direct, collaborative, and genuinely curious about the person sitting across from me. I don't believe therapy should feel clinical for the sake of sounding clinical, and I don't believe my role is to simply tell you what you should do. I want to understand how you got here: the experiences that shaped you, the patterns you've developed, what those patterns may have helped you survive or manage, and whether they're still serving you now. From there, we can figure out together what you want to keep, what you want to change, and what moving forward can actually look like for you.
