Cynthia Adams, LCSW-R
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.

Collette Jones, LCSW
​
Collette works primarily with anxious, self critical adults and teens, especially women, who feel stuck, overwhelmed, or exhausted from trying to “do everything right.” Many of the clients she works with identify as perfectionists or high functioning on the outside while feeling emotionally drained or disconnected on the inside. Her work focuses on helping clients slow down, reduce internal pressure, and untangle unhelpful expectations rather than pushing harder when something isn’t working. Collette believes meaningful change comes from creating safety, understanding patterns, and finding greater alignment between values, needs, and expectations, rather than forcing productivity or constant self improvement. Collette integrates mindfulness-based, CBT and ACT informed approaches, along with somatic informed practices and practical skills, tailoring therapy to each individual rather than relying on rigid formulas. Her style is collaborative, compassionate, and grounded, with space for humor and real life insight. Outside of the therapy room, Collette enjoys reality TV and spending time with family, friends, and her Cavalier King Charles Spaniel, Gus.
