Turn Your Life Experience into a Career

Our program offers flexible entry, hands-on training, and strong community connections to prepare you for work in social services, substance abuse counseling, and case management. No prior experience or degree is needed—just a commitment to making a difference. With pathways to employment, further training, and transfer opportunities, COSER provides the support and education you need to create change in your community.

“This program has given me the tools to become a substance abuse counselor as well as the opportunity to give back to my community.” - COSER Alumni

No matter where you're starting from, COSER is here to help you take the next step toward your future.

  • With flexible start dates, you can begin anytime — morning or evening, all year round. 
  • There’s no GED required, and support is built in through tutoring and mentoring with Street Scholars. 
  • Need a laptop? We've got you covered with a free laptop loan program and computer training to build your skills. 
  • COSER welcomes all students, including those with criminal records, and offers financial aid that doesn’t require taking out loans. We even help with book costs—because your success should never be out of reach. 

New to School or Haven’t Been in a Long Time? Meet the Street Scholars!

Our peer-mentoring and student support program — designed by, and for formerly incarcerated and system-impacted individuals — provides academic support, advocacy, and mentorship. We foster connection and empowerment, ensuring students are understood and guided through their educational and reentry journeys.
