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.

Hello and welcome! I work with individuals and couples experiencing relationship transitions. I work in-person on Tuesdays in Ridgewood and virtually Monday-Thursday, 10-6. I currently have mid-day in person and virtual availability.

I believe relationships-both with the self and with others- are worth working on. I have been a practicing social worker for over a decade and have focused on psychotherapy for the last five years. In addition to training in social work and psychotherapy, I have a Certificate in Couple Therapy from Akerman Institute and have completed over 60-hours of training in the Understanding Model of mediation. I have extensive training on modalities for treating anxiety, OCD, and depression.

I am a psychodynamic psychotherapist who works with Individual adults and adolescents, many of whom identify as LGBTQ+. I specialize in working with anxiety, depression, trauma, and questions of identity. I have an MSW degree from NYU, where I interned with a psychoanalytic institute. I also earned a BA in Philosophy from The New School.

I am a New York state and New Jersey state licensed clinical psychologist. I received my doctorate in psychology from Long Island University-Post. I completed an APA accredited internship from Mt. Sinai Services-Elmhurst Hospital Center. I received postdoctoral training from New York University Counseling and Wellness Services. I specialize in working with adults with concerns regarding career, relationships, life transitions, identity, anxiety, eating disorder/body image, and grief/loss.

What if improving your relationships isn’t starting together, but starting with you? As a Marriage and Family Therapist (LMFT), I work with individuals who are curious about their relationship patterns and ready to create meaningful change from the inside out. You may feel stuck in recurring dynamics, find yourself questioning how your family background shapes your relationships, or want to communicate more effectively. Together, we create a space to gain clarity, better understand what’s driving these patterns, and begin making intentional shifts toward healthier, more balanced relationships.
