The Recovery Station


Genesee/Orleans Council on Alcoholism and Substance Abuse, or GCASA, has served residents of Western New York for almost five decades. Founded in 1975, GCASA started with a focus on the prevention and treatment of alcohol and drug use, and has grown and expanded dramatically since. We now serve residents in Genesee and Orleans Counties, working with a team of more than 125 people and an operating budget of more than $7 million annually.

Since our formation, we have broadened our programs, as well. We offer residential and detox services, recovery services, and an employee assistance program that helps to provide counseling, grief support and other programs for employers to help deal with issues that affect productivity.

Prevention Programs

We offer several proactive prevention programs aimed at educating and informing people of all ages in the region of the risks of addiction and behaviors to avoid to live a healthy and happy lifestyle. Our services include community and school based programs.  We also provide responsible server training for businesses.  Our programs are evidence based and approved by NYS Office of Alcoholism and Substance Abuse Services.  Our community outreach and partnerships allow us to provide educational information and sound prevention strategies with proven successful outcomes.

Treatment Services

Our treatment services are designed to be patient centered, meaning that each individual receives services that meet their unique needs. Treatment programs include dedicated services for teens, men and women, opioid and gambling treatment, medication assisted treatments, and treatment regimens that are customized for those with co-occurring disorders.  We recently opened our Opioid Treatment Program (methadone clinic) at our Batavia location and launched our mobile treatment unit and peer services; bringing help to community members where they are at.

Residential & Detox Center

In Batavia, the Atwater Home Community Residence offers men in recovery a supportive environment to help them with their journey through overcoming substance use disorder. Offering necessary services and support in a structured, chemical-free environment, the Atwater Home Community Residence has been serving Western New York for more than two decades, helping countless individuals develop healthy living skills through treatment and support for all their mental, physical, psychological and spiritual needs.  In addition, we have 24 supportive living beds, serving both men and women in the community.

Located directly behind the Atwater Home, we have our Detox Center which provides medical withdrawal and stabilization to people who are struggling with a substance use disorder. Our role is to reduce the amount of an addictive substance in a patient’s body, provide reasonable control of active withdrawal symptoms, and avert a life-threatening medical crisis. 

Recovery Services

GCASA has a variety of support services to help people on their own path to recovery. We also have support available for family members of people who are actively using drugs or alcohol.  Everyone’s path to recover is different and we’re here to support yours.

We are changing the way we communicate with our community and school partners and would like you to opt in to receive emails from us.  We would like to send periodic emails with information regarding our prevention, treatment, and recovery services, company news and announcements, and our annual scholarship opportunity.  We promise not to send too many (and you can unsubscribe if it’s not working out for you).  Please subscribe so you don’t miss out on important GCASA news.
