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.

Do you notice patterns of behaviors that you are unsatisfied with? Therapy is a significant step towards working through and facing life's most difficult challenges. I have worked with adults, adolescents and children treating issues of adjustment, self-doubt, mood swings, trauma and anxiety attacks. When you approach the therapeutic process with curiosity, you can grow, heal, and thrive.

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 am a clinical psychotherapist with almost a decade of experience working with couples and adults who want to better understand themselves, and work towards creating the lives and relationships they crave. I am passionate about helping people reconnect to themselves, their hopes, and their autonomy. I specialize in relational/marital challenges, anxiety, grief, addiction, eating disorders, and trauma.

I specialize in working with adults ages 18-40, focusing on religious trauma, life transitions, grief, self-esteem, relationships, and LGBTQIA+ issues. My work is rooted in psychodynamic therapy and incorporates CBT & DBT skills according to each client's needs.

I am a licensed clinical psychologist in New York State, practicing out of New York City. I work with adolescents and adults who experience a range of difficulties, including anxiety, depression, the after-effects of trauma, overthinking, procrastination, low self-esteem, relationship issues, and challenges related to identity and values. I also specialize in working with family members of individuals who suffer from severe mental illness.
