Hi! I'm Dr. Adina Chesir, a licensed clinical psychologist specializing in evidence-based treatments for anxiety, OCD, and other related concerns. I also have expertise in parent coaching for parents of children with anxiety and behavioral challenges. I work with children, teens, and adults who feel stuck in patterns of stress, overthinking, or avoidance that are hard to break. My approach is practical and collaborative, drawing from Cognitive Behavioral Therapy (CBT), Dialectical Behavior Therapy (DBT), and Acceptance and Commitment Therapy (ACT). Together, we focus on both understanding what’s keeping you stuck and building concrete tools to help you respond differently so that anxiety has less control over your day-to-day life.

I earned my PhD in Clinical Psychology in 2002. Having worked in healthcare and academic settings, I appreciate being part of a treatment team and am available to coordinate care with other providers when beneficial. Rather than see 'how many problems' a person may be facing... I see 'how many ways things can get better'. I value working with folks to see their puzzle from a different angle and to use tools to clarify, change and improve the picture.

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.

I am a psychodynamic psychotherapist who works with Individual adults and adolescents, many of whom identify as LGBTQ+. I specialize in working with anxiety, depression, trauma, and questions of identity. I have an MSW degree from NYU, where I interned with a psychoanalytic institute. I also earned a BA in Philosophy from The New School.

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.
