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. Over the years, I’ve had the privilege of caring for individuals with both medical and psychiatric conditions, which deepened my understanding of the powerful connection between the mind, body, and overall well-being.

I have a particular passion for working with men, especially guys in their 20s and 30s. A lot of the young men I see are dealing with something the research is only now catching up to — an erosion of in-person connection, a sense of drift, and a shortage of spaces where they can actually say what's going on. I'm genuinely excited and motivated by this work because I believe this generation of men needs — and deserves — real support. That said, I also welcome clients navigating anxiety, discouragement, depression, workplace stress, relationship dynamics, and life transitions of all kinds.

I'm a Brooklyn-bred Psychotherapist and earned my LCSW in 2009. I previously worked in the corporate world, and understand pressure, ambition, career transitions, and what it feels like when the thing you've built your identity around stops fitting. Since becoming a therapist, I've worked in hospitals, outpatient clinics, substance abuse treatment, and psych rehab before settling into a private practice where I'm focused on the work I care most about.

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.

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.

Therapy is a collaborative process, and a strong therapeutic relationship is key to meaningful progress and lasting change. My approach is grounded in a strengths-based, client-centered perspective that supports each person’s capacity for growth and self-understanding. I strive to create a supportive, compassionate, and nonjudgmental space where you can openly explore your thoughts, emotions, and experiences at a pace that feels comfortable for you. Whether you are navigating life transitions, managing stress, or seeking greater self-awareness, therapy can provide a space for reflection, healing, and meaningful change.
