About

For the past 30 years, RevCore (formerly NYCATS) has been helping individuals with mental health and substance use disorders build a future of enduring health, wellbeing, and stability, and the opportunity to create a better life for themselves and their families.

Our mission

Our mission is to inspire growth, healing, change, and above all, hope.

Hope—the deep belief that better things lie ahead—is the foundation of recovery.

Hope lifts people out of despair.
Drives them to reclaim control of their lives.
Gives them permission to lean into their potential.

At RevCore, we help people rediscover the hope they’ve lost—so they can break through pain and hurt, scrape off layers of trauma, and work toward meaningful, lifelong change.

Our philosophy

No two journeys to recovery are the same. Yet every one of our clients has something in common.
Our clients are not their illnesses or addictions. They are human beings worthy of belonging, deserving of compassion, and capable of change, regardless of their past or current struggles. In every individual who comes through our doors, we see:

People, not problems

Our clients are not problems to be fixed. They are individuals with their own stories to tell—and the power to write their own endings.

People, not diagnoses

A diagnosis doesn’t define a person, or indicate inherent brokenness. It’s a tool for understanding, treating, and caring for our clients. Nothing more.

People, not pasts

Everyone deserves a second chance. Given the proper support, tools, skills, and care, every person has the ability to turn their life around.
