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 am a Double Board-Certified nurse practitioner specializing in psychiatric mental health and family health. As a dedicated psychiatric nurse practitioner, I use an integrative and holistic approach to mental health. As a family nurse practitioner, I take into consideration how physical health impacts mood and relationships. I employ evidence-based medication management. Together, we can pinpoint what's causing you stress and navigate towards a balanced state. I employ brief supportive psychotherapy in every session to help patients manage their emotions, particularly those dealing with chronic illnesses or experiencing high levels of stress. By offering empathy and validation, I aim to strengthen coping mechanisms, boost resilience, and enhance overall mental well-being.

Each client is an individual which requires not a one size fits all treatment approach. I have over 10 years of prescribing experience in inpatient and outpatient settings and understand that not every person requires the same treatment plan. I also provide MAT, ie, suboxone, vivitrol, naltrexone for Opioid Use Disorder and Alcohol Use Disorder in a non judgmental private setting.

I also treat all anxiety disorders, mood disorders, ADHD/ASD and am understanding of neurodivergence in treatment as well. I have a vast understanding of psychopharmacology and incorporate that into each appointment to help provide the best care possible for each patient. I can help deprescribe if you choose to as well. Not every patient needs to continue medications if they choose not to.

I’m Linda Orji, a Board-Certified Psychiatric Mental Health Nurse Practitioner (PMHNP) with over Eleven years of experience in health care. I earned my Master of Science in Nursing from the University of Rochester in Rochester, NY.

I am a board-certified psychiatrist and psychotherapist with expertise in medication management, psychoanalysis, CBT and mindfulness-based therapy. I also have expertise in interventional treatments and work as a clinical professor at Northwell Zucker Hillside Hospital. I work with adults and have openings in the evening and weekends for busy working professionals. I specialize in treating a wide array of conditions: Depression, Anxiety, OCD, Social Anxiety, ADHD and Insomnia. At this time, I am only taking patients who are interested in medication management not individual therapy. I also do not take patients needing medical leave from work.

I am a psychiatrist with years of further training and experience in psychodynamic psychotherapy and psychoanalysis. I treat a wide array of issues, ranging from anxiety, depression, grief, problems in intimate relationships, and chronic dissatisfaction to a general sense of malaise. I also work with patients who are experiencing confusion about their feelings and an inability to make important decisions, and who thereby feel stuck and unable to move forward. In addition, I help patients going through a crisis or a life transition that may lead to an increased burden of demands requiring change.

I work with patients to help them recount and revisit their life's story and create a new narrative that works better for them. In that spirit, I don't give overt advice, instructions, or quick solutions, but instead encourage them to arrive at their own solutions after carefully exploring the roots of their current problems.

I have a judicious approach to prescribing medications when warranted to support the work of therapy.
