About Us

Established in 1969, Keystone Substance Abuse Services has provided our community expert care and hope that recovery from substance use is possible. We have worked with countless people struggling with substance use disorders, their families, and community members to treat not only the symptoms of substance use, but to also educate, empower, and heal the people behind the addictions to improve the quality of life of the individual, their families, and the community.

The word “keystone” refers to the architectural stone piece that provides connection and strength to the two sides of an archway. With this imagery in mind, for over the last 50 years, Keystone bridged the gap between substance use and recovery, and provides people who might be struggling with the strength, integrity, and empowerment they need to begin their recovery journey.
