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 have had the pleasure of working with a variety of clients through their struggles and transitions. I work with my clients to explore which therapeutic approach works best and provide them with different treatment strategies and skills to deal with their challenges. I have worked in inpatient, outpatient and correctional settings and have experience with depression, anxiety, OCD, PTSD, psychosis, Schizophrenia, Bipolar disorder, Schizoaffective disorders and personality disorders. I particularly enjoy working with clients who experience anxiety, panic and OCD for which I utilize CBT via Exposure Response Prevention (ERP), Exposure Hierarchy and mindfulness. All of my experiences have made me an empathetic and nonjudgemental mental health provider who realizes the importance or providing mental health treatment.
I’m Theo Bizimana, a Licensed Mental Health Counselor in New York. I hold a Master’s degree in Counseling Psychology from Daystar University in Nairobi, Kenya, and an Advanced Certificate in Mental Health Counseling from the University at Buffalo. I bring more than 17 years of experience supporting individuals and communities, including over 11 years of work focused on community trauma in East Africa and 6 years of clinical experience in the United States.
