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’m Dr. Joseph Yanni, a licensed psychologist who works with teenagers, college students, young adults, adults, parents, and families navigating anxiety, ADHD, emotional regulation, school and college stress, relationship challenges, and life transitions. I earned my Psy.D. in School Psychology from Fairleigh Dickinson University and continue to work as a school psychologist, supporting students with emotional disabilities in a specialized educational setting. This experience has given me a practical understanding of how emotional, academic, social, family, and developmental concerns often overlap.

I use a collaborative, practical, and integrative approach that draws from Cognitive Behavioral Therapy (CBT), psychodynamic therapy, humanistic and person-centered therapy, behavioral strategies, and lifestyle-based interventions. I believe therapy should be individualized rather than following a one-size-fits-all model. Together, we work to better understand what is contributing to the concern, build practical coping skills, strengthen relationships, and develop realistic strategies that create meaningful change.

I work especially well with teenagers, college students, young adults, and parents navigating the transition from adolescence into adulthood, while also supporting adults and families facing anxiety, relationship concerns, and other important life challenges. I provide in-person therapy in Scarsdale and Pleasantville, along with virtual therapy throughout New York State.

What I want clients to know about me is that I am not the kind of therapist who will just sit back, nod, and ask, “How does that make you feel?” I am warm, honest, direct, and very involved in the work we do together.

My strongest area of work is relationship and family dynamics. I help individuals, couples, and families understand the patterns that create conflict, distance, resentment, poor communication, and emotional disconnection. Many of my clients come to me feeling unheard, disrespected, emotionally exhausted, or unsure of how to move forward in an important relationship.

I also work with people who grew up in difficult or dysfunctional family environments and are now recognizing how those experiences may still be affecting their boundaries, relationships, parenting, self-worth, and emotional responses. I help clients understand not only what is happening, but how the pattern developed and what they can begin doing differently.

I believe insight is important, but insight alone is not enough. I want therapy to help you connect the dots and develop practical ways to communicate, set boundaries, manage conflict, and respond differently. I will support you, but I will also challenge you when I believe you are minimizing your needs, repeating unhealthy patterns, or avoiding something important.

I am not here to judge you, label the people in your life, or tell you what decisions to make. My role is to help you see things more clearly, understand what is within your control, and feel more confident in how you choose to move forward.

In addition to relationship and family concerns, I also work with anxiety, ADHD, emotional overwhelm, life transitions, and the impact these challenges can have on everyday functioning and relationships.

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 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. For patients needing documentations for medical leave, following are my fees: $100 per form and $25 per letter.

Hello, I’m Vincent. I am a Licensed Psychoanalyst/Psychotherapist (LP) with a private practice in Manhattan, offering both in-person and telehealth sessions. I bring my own lived experiences and cultural attunement into the room to build a deeply trusting and authentic therapeutic alliance with my clients.
