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.

Does your child or adolescent’s behavior leave you wondering, “What is going on?”Are they having meltdowns, withdrawing, struggling at school, worrying, or feeling sad? Children and adolescents often communicate their feelings through behavior long before they have the words to explain what they are experiencing.I work with children, adolescents, and families navigating challenges such as adoption, divorce, co-parenting, blended-family transitions, grief and loss, school-related worries, family conflict, and the growing push for independence. I help children and caregivers better understand what may be underneath the behavior while strengthening connection, communication, and emotional regulation. I am a Licensed Clinical Social Worker (LCSW) and Registered Play Therapist-Supervisor (RPT-S). I received my Doctorate in Clinical Social Work (DSW) and Master’s in Social Work (MSW) from New York University, and my Bachelor’s of Science in Social Work (BSW) from Cornell University. With more than two decades of clinical experience across inpatient, outpatient, and residential settings.

I am an LMHC in New York. I have been in private practice since 2015. I obtained my Master's Degree in Mental Health Counseling in 2012 and began working in a residential setting, providing services to adults with chronic mental illness and substance use disorders, receiving numerous promotions along the way. After 11 years, I decided to move onto something new, obtaining a position as a Clinical Director in an outpatient clinic. I recently decided to pursue my private practice full time.

Reaching out is hard, especially if you've already tried therapy before and it didn't quite get you where you needed to go. I want you to know that doesn't mean something's wrong with you, it usually just means the approach wasn't the right fit. I've spent over a decade working with people carrying trauma and addiction, adults and teens both, and what I care about most is helping you feel truly understood, maybe for the first time, before we even get to the work of healing.

I believe prioritizing mental health is key to stability in life. I know there is a better world out there and people need the tools to connect with their upmost insight for mental well being. In this field I am always eager to research and find healing processes to tailor the need of each individual.

Gila Schwartz is a therapist located on Long Island, NY. A psychologist focuses on the evaluation, prevention, diagnosis, and treatment of mental, emotional and behavioral health issues. A clinical psychologist uses psychotherapy and other counseling skills to improve emotional and mental health.

I view therapy as a collaborative process where clients are invited to make sense of their experiences in a way that feels authentic to them. Rather than directing the process, I focus on creating a supportive environment where individuals can speak openly, reflect at their own pace, and gain insight into their thoughts and emotions. In the midst of busy and often overwhelming daily life, having intentional time to pause and look inward can be a powerful part of personal growth.

Creating room for reflection can open the door to new perspectives and a deeper awareness of internal experiences. As clients begin to better understand their emotional responses and patterns, they often find greater clarity in how they relate to themselves and others. This increased awareness can support more intentional decision-making and help guide the next steps in their personal growth.

It's very difficult to be in stressful situations that can cause lots of anxiety and self-doubt. Perhaps you're looking for something more than advice from family and friends. If you're looking for a warm and inviting counseling atmosphere, I am eager to work with you to develop effective coping skills and a greater self-awareness to reach your full potential. Together, you and I can work to set goals that are appropriate and attainable for you, at your pace. For therapy to be effective for you, I work hard to build genuine and long lasting trust.

I have experience working with clients who have suffered from anxiety, depression, and marital issues. Additionally, I believe that cultural factors are critical to the way we navigate through life. I work hard to address cultural matters, to understand how these may impact our perception of the world.
