My hope is that Triangle Cognitive Therapy will continue to be the vehicle to improve our ability to teach the ideas and skills of CBT in an effort to reduce the stress, anxiety, and depression that our community experiences.


about me


Growing up, I never saw myself as a therapist. After graduating college it became clear to me that what I wanted most was to provide direct services to those who are suffering, and I was keen to learn more about how people think, feel, how these things affect their choices in life. This initiated my journey to becoming a therapist.


I graduated from Columbia University School of Social Work with a Masters in Social Work. After six years of work experience and training, I became a Licensed Clinical Social Worker (LCSW). I started my career working with homeless adults who were struggling with drug addiction. I then became a Credentialed Alcohol and Substance Abuse Counselor (CASAC) and for the next 14 years, worked as a therapist, supervisor, and administrator for an agency that provided addiction treatment and prevention services to teens, adults, and families. 

Then, in 2011, I opened up a solo practice in Rockville Centre, New York. The practice was designed to offer services to teens, young adults, adults, couples, and families who are looking for help with various mental health and relationship issues. While building the practice, I sought out training and supervision in Cognitive-Behavioral Therapy (CBT) and achieved my Diplomate from the Academy of Cognitive and Behavioral Therapies. This evidenced-based modality of treatment is highly effective in treating most mental health disorders.  


In addition to working with individuals, I have extensive experience with group and family therapy both in clinics and in schools. I have also developed and presented to middle/high school and college students on various health topics such as substance abuse issues, stress management, healthy decisions, and dating violence. 

my therapeutic approach

For many years, I have naturally gravitated toward the Cognitive-Behavioral Therapy (CBT) model. This evidenced-based model focuses on the idea that our thoughts, feelings, and behaviors are all connected, like the points of a triangle. 


Often, when we find that our behavior is dysfunctional, it is usually connected to distorted thoughts and feelings. CBT teaches us how to become mindful of our distorted thinking and how it affects us emotionally and behaviorally. In my experience, this approach is very effective in helping to create a change in life. 

If you have any questions about CBT or the practice, you can contact me at or call me at (516) 208-3792 ext 21.


In 2018, I formed Triangle Cognitive Therapy, a group practice serving adolescents and adults in the community. In following the adage that "two heads are better than one", my thinking was to create a multi-disciplinary group of clinicians in order to expand the scope of the practice and be able to provide increased and more specialized services to the community.  

Over the last 2 years, Triangle Cognitive Therapy has grown from a company of one to a group of highly experienced clinicians, who have done some amazing work with our clients.

In these two years, we have developed a group therapy program, started offering online therapy (in response to the COVID-19 crisis), and continued to develop and build our relationships with the local community. Our plan for the future is to continue to strengthen our relationships with schools and other mental health providers in the community, expand our group therapy program, and develop a psychoeducational seminar series for those looking for more information about coping strategies and techniques for a variety of mental health difficulties.
