Our Alumni

We understand that recovery is a lifelong journey, and we’re committed to supporting our clients even after they leave our South Dakota facility. Our alumni program extends the care individuals receive during their time with us, offering a community of peers who have had similar experiences and can walk the path to recovery together.

Through regular events, lasting friendships, and recovery-focused groups, our alumni program helps former clients stay engaged and motivated. By building and fostering this strong community, we create a space where alumni can continue to grow, find encouragement, and maintain a substance-free life.

Keystone’s alumni program includes a weekly meeting called Recovery Maintenance, held every Thursday night at 7 p.m. at our Keystone Outreach Office in Sioux Falls. This is a topic-based gathering that follows a 12-Step meeting format. Meetings last about an hour and include a HIPAA-compliant sign-in sheet, emphasizing confidentiality with the agreement: “Who you see here, what you hear here, let it stay here.” The group is made up of alumni who are actively working the Steps, as well as others who attend because it’s a safe, supportive environment. The only requirement is honesty. The group size ranges from 15-30 attendees, and fellowship is encouraged before and after the meeting. Coffee is provided!

Additionally, we offer a monthly Zoom meeting where a longtime alumnus (from 1984) shares insights on one of the 12 Steps, followed by an open discussion. This meeting takes place on the third Wednesday of each month at 7 p.m., covering a different Step each month, including “Step Zero” (attend in January to learn more about it!). To participate, alumni can email Outreach Director Jason Stricklin to request the Zoom invite, which is sent out prior to each month’s meeting.

Keystone hosts an annual alumni event where former patients and their families can come together, celebrate recovery, and share in fellowship. For many, this event is a highlight of the year, offering a chance to reflect on their progress and enjoy the support of their extended Keystone family.

This special occasion typically begins on a Saturday afternoon at our facility in Canton, South Dakota, and continues with evening activities in Sioux Falls.

At Keystone Treatment Center, we firmly believe in two guiding principles: first, that recovery from addiction is possible, and second, that recovery is a lifelong process best pursued in the company of others. While residential or outpatient treatment may be a crucial first step, our dedication to your success continues long after you leave our doors. We are committed to walking with you and providing the community and support you need to thrive in your new life of recovery.

• Minimum of six months in recovery
• Actively working the 12 Steps
• Have a sponsor in AA, NA, or GA
• Be willing to share honestly and openly about your journey in recovery

If someone you care about is struggling with addiction, Keystone is here to help. Simply provide a brief description of what your friend or family member is going through, and we will be happy to reach out to you directly to discuss potential options and resources that could be helpful. You do not need to give us any personal details, and all the information you share will remain confidential. Our goal is to support you and your loved ones in finding the right path to recovery.
