Find a therapist in Jamaica, NY — covered by insurance

Hi, I'm Jean-Jeffrey Marcellus, DNP, PMHNP-BC, AGNP-BC, a board-certified Psychiatric Mental Health Nurse Practitioner with over 19 years of healthcare experience. I provide compassionate, evidence-based care for adults experiencing ADHD, anxiety, depression, insomnia, and substance use disorders.

I specialize in Medication-Assisted Treatment (MAT) for alcohol, opioid, benzodiazepine, kratom, and prescription medication dependence. My approach is collaborative and personalized, focusing on creating treatment plans that support each individual's goals, recovery, and overall well-being.

I offer both in-person and telehealth appointments, providing a welcoming, judgment-free environment where patients feel heard, respected, and empowered. I am committed to delivering culturally responsive care and making high-quality mental health services accessible to individuals from diverse backgrounds.

I believe prioritizing mental health is key to stability in life. I know there is a better world out there and people need the tools to connect with their upmost insight for mental well being. In this field I am always eager to research and find healing processes to tailor the need of each individual.

Reaching out is hard, especially if you've already tried therapy before and it didn't quite get you where you needed to go. I want you to know that doesn't mean something's wrong with you, it usually just means the approach wasn't the right fit. I've spent over a decade working with people carrying trauma and addiction, adults and teens both, and what I care about most is helping you feel truly understood, maybe for the first time, before we even get to the work of healing.

The core of my work has been to help people find solutions that work, to problems that prevent them from moving forward and living satisfying lives and relationships. I help people who feel stuck, to overcome life’s challenges, regain control of their lives and become the managers of their own self. Over the last 17 years I have been working with adults, teenagers and children from different cultures both in the US and overseas. Through my specialization and experience in severe and persistent mental illness I help people tackle emotional and communication difficulties that interfere with their relationships with friends, family

and the workplace. In my clinical work, I use evidence based psychotherapeutic approaches that have been proven effective through time. In a compassionate, and supportive environment I help people deal with a variety of problems like anxiety, trauma, obsessive compulsive disorder, depression, bipolar disorder, psychotic disorders, personality disorders,

emotional, relationship issues and divorce. I have extensive experience working with veterans, college students, substance abuse and LGBD individuals. In addition to individual therapy I do parent consultations for children and teenagers.

I believe therapy should be a space where you can be completely yourself without fear of judgment. I am a Licensed Creative Arts Therapist (LCAT) and Registered Art Therapist (ATR) with over 10 years of clinical experience and have been in private practice for the past seven years. I earned my Master's degree in Art Therapy from New York University and previously worked with children, adolescents, adults, and older adults in inpatient psychiatry at Mount Sinai Hospital. My approach is integrative, trauma-informed, and person-centered, incorporating CBT, DBT, art therapy, and additional training in Jungian and Internal Family Systems (IFS)-informed approaches. Together, we'll build practical skills, deepen self-awareness, and create meaningful, lasting change

As a clinical psychologist, I assist patients in reshaping negative thought and behavior patterns in a judgement free setting.
