I specialize in mood disorders, dual diagnosis, and personality disorders, and I bring deep personal motivation to this work — mental illness has touched my own family, and that experience shapes how I show up for every client. I know how prevalent it is, and I believe with my whole heart that there is no shame in struggling or in seeking help. My greatest strengths are patience and a genuine drive to help people transform how they feel and rediscover that life can be better. Outside of sessions, I enjoy thrifting, exploring new foods, and spending time outdoors with my family.

I am a U.S. Navy veteran that came to therapy late in life after a successful career in Tech. I am very analytical but also empathic, compassionate and humorous.

I am a triple board‐certified Family Nurse Practitioner (FNP), Certified Nurse Midwife (CNM), and Psychiatric Mental Health Nurse Practitioner (PMHNP). This unique combination allows me to care for individuals across the entire lifespan, with a deep understanding of how physical health, hormones, trauma, environment, and life transitions shape mental well‐being.

My approach is collaborative, integrative, and rooted in both conventional psychiatry and functional medicine principles. I work to understand the root causes of symptoms—not just treat them—by considering biological, psychological, hormonal, nutritional, and environmental factors. Treatment plans may include medication management, lifestyle strategies, mind‐body approaches, and supportive therapy.

My style is warm, patient‐centered, and grounded in partnership. We build your plan together, ensuring it is evidence‐based, individualized, and flexible as you grow. Whether you’re navigating anxiety, depression, trauma, mood changes, or complex mind‐body concerns, my goal is to meet you where you are and support you toward lasting emotional and physical wellness.

Passion has brought me to this field, and I would like to be there for people in ways I wish people are there for me, by creating a safe, nurturing, empowering, and growing environment for my patients to explore and heal within the depths of their hearts. I have extensive experience in the inpatient setting from having helped patients with diverse presentations, while integrating multiple modalities into my treatment and having knowledge of the appropriate medications needed from having worked closely with psychiatrists. I have completed my MS degree from the State University of New York. I also have a postgraduate diploma in Islamic Psychology from Cambridge Muslim College.
