Find a therapist in Mount Kisco, 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 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.

If this is your first time seeking therapy, or if you have been in therapy before you are welcome here.

I have years of clinical experience specializing in Trauma, Relationship Issues, as well as individuals with ADD/ADHD and individuals with Asperger's Syndrome. In addition to having a master's degree in Art Therapy from Pratt Institute, I have postgraduate training in Psychodynamic-Psychoanalytical Therapy, working with children and teens. Dance/Movement Therapy, and Drs. John and Julie Gottman Method. I have years of experience utilizing Dialectical Behavior Therapy (DBT), Cognitive Behavioral Therapy (CBT).
