Book a therapist or psychiatrist in East Islip, NY covered by Cigna

I became a social worker because I believe people are more capable of change than they are often given credit for—they need the right support to get there.

I'm a licensed clinical social worker with over a decade of experience working with individuals, families, and couples of all ages. I specialize in anxiety, depression, trauma, stress and mood disorders, ADHD, autism, and emotional dysregulation — but I'm always focused on the whole person, not just the diagnosis. I also work closely with parents and caregivers, because some of the most powerful change happens when the people around you understand you better, too.

I am a Licensed Clinical Social Worker who obtained my Master of Social Work from Binghamton University. I have experience working together with diverse populations and various ages, ranging from children to adults.

Did you know that everything is working in your favor?! Struggling with anxiety, depression, trauma, or mood changes that make everyday life feel heavy? You don't have to figure it out alone. I'm Dr. Denise Williams, a board-certified Psychiatric Mental Health Nurse Practitioner (PMHNP-BC) with a Doctor of Nursing Practice (DNP) and over 14 years of experience in psychiatry. I provide psychiatric evaluations and medication management for teens (12+) and adults through convenient, 100% virtual telehealth visits.

I help clients with anxiety, depression, PTSD and trauma, bipolar disorder, ADHD, personality disorders, schizophrenia, grief, and stress. I have a special interest in women's mental health, and I'm deeply honored to work with veterans and their unique experiences.

My background in psychiatric crisis stabilization and correctional mental health taught me to meet every person where they are, with no judgment. I welcome clients of all backgrounds, races, and cultures, because culturally humble, affirming care is essential, not optional.

A big reason why I became a therapist is reflected in the quote: "Your vocation is where your deep gladness meets the world's deep need" (Frederick Buechner). I find tremendous joy in helping clients move toward healthier and more meaningful lives.

Hi there!

I am a bilingual (English and Spanish) Latine and Neurodivergent Licensed Psychotherapist based in New York City, offering sessions via Telehealth.

I specialize in working with:

• Autistic, AuDHD, ADHD (self-identified and/or formally diagnosed) people
• Latinx Immigrants &
• LGBTQIA2+ individuals

I consider therapy a sacred space; a place I feel honored to co-create with the people I work with. I am passionate about making space for people's life stories and any situations they are navigating in the present.

Know that I've spent years working directly inside crisis-level mental health care - supporting adults through an ER psychiatric unit where depression, anxiety, and substance use often show up together and go unaddressed for a long time. I bring that same steadiness to private practice. Expect a therapist who has seen a lot, doesn't flinch, and treats you as a full person rather than a diagnosis. I work with adults 18 and up, and I hold space in particular for people navigating chronic anxiety, depression, trauma, relationship strain, and co-occurring substance use.

I am dual board-certified as a Psychiatric Mental Health Nurse Practitioner and Family Nurse Practitioner. After several years of clinical practice, I earned my doctoral degree in 2021. My experience spans both behavioral and family health settings, including hospital-based behavioral health units, partial hospitalization programs, and intensive outpatient care.

I specialize in the diagnosis and treatment of a wide range of mental health conditions, including ADHD, depression, anxiety, bipolar disorder, OCD, panic disorder, and PTSD. My approach is grounded in evidence-based practice and emphasizes holistic, collaborative care.

Together, we will develop a personalized treatment plan tailored to your unique needs, goals, and values through a shared decision-making process.

I am committed to creating a supportive, nonjudgmental environment and to addressing disparities in mental health care. If you’re struggling, you don’t have to go through it alone. I’m here to support you with compassion, expertise, and care.
