Cynthia Fischer - Clinical Supervisor and Consultations

After graduating from SUNY Stony Brook in 1990, I established a private practice on Long Island. My primary focus has always been relationship issues. About 20 years ago, I began incorporating an understanding of how and why the brain functions as it does. When we have an understanding of our brain (and the brain of our partner), we can significantly increase the likelihood of getting what we want in our relationships. This additional emphasis has enabled me to help my clients gain better understanding and increased mastery in their lives and relationships.


During my career, I have also developed a specialty in Anxiety Treatment, and have found that my education about how the brain functions is often helpful in treating this condition as well. I have additionally had success treating people with a model that incorporates several clinical theories including, but not limited to, Cognitive Behavioral and Family Systems Therapy.
