Marc J. Shulman, PsyD:
My name is Dr. Marc Shulman, and I derive great joy from working as a clinical psychologist on Long Island. I graduated with my doctorate degree from Yeshiva University, and I am the founder of Long Island Psychology. I served as an Associate Research Scientist at Yale University and Program Director in the Clinical Health Psychology department at the VA Connecticut Healthcare System, while operating a private practice in Stamford, CT. Upon moving to Long Island, I accepted a core faculty position in a nationally recognized program at the Northport VA Medical Center and continued practicing privately out of multiple locations in Garden City, Lawrence, and, more recently, Rockville Centre.


Through my training, research, and experience working as a licensed clinical psychologist, I have helped people from diverse populations cope with a variety of presenting issues. I have used my understanding of people and the therapeutic process to develop a unique and effective treatment approach called Dynamic Experiential Learning (DEL). This method integrates various theoretical concepts with careful, focused evaluation and customized interventions for each individual, couple, or situation.


I have also created businesses that provide vulnerable populations with greater access to mental health services, workshops designed to enable people to maximize their full potential, and psychological tools for corporations to facilitate enriched consumer experiences. Additionally, I have supervised many graduate students in their clinical training, published clinical research in various psychology journals and
presented at several conferences, and developed treatment manuals that are utilized for research and training purposes at leading educational institutions and hospitals. I sincerely enjoy all aspects of what I do, and I am thankful for the opportunity to help people craft more productive and happy lives.


Atara Wertentheil, PhD:
My name is Dr. Atara Wertentheil, and it is my privilege to be working within the Long Island
Psychology practice where I empower clients to transform their relationships, perspectives, and circumstances for the better. I received my masters in Mental Health Counseling and my PhD in counseling psychology from Fordham University. I have worked in a variety of clinical settings, including outpatient mental health, university counseling, and private clinics, where I have had the opportunity to refine my clinical knowledge and skills. I was recognized by the American Psychological Association for my work with college and graduate students, and I am trained to provide culturally sensitive services to people of all ages with a wide range of struggles including mood issues, marital or family relationship instability, grief/loss, addiction, career dissatisfaction, identity concerns, and/or stress
related to life’s demands and transitions.


It takes courage and vulnerability to start the process of therapy. Once my clients and I, together, identify an approach with the most potential for success, I help to facilitate constructive life changes while also offering support and encouragement each step of the way. I aim to establish a productive, warm, and nonjudgmental therapeutic relationship with my clients while respecting the unique qualities, strengths, goals, challenges and contributions that each person brings. I look forward to helping my clients learn, grow, and heal through the therapeutic process.
