Cornerstone Montgomery is a mission-driven nonprofit organization committed to helping people with mental health and substance use disorders achieve meaningful, fulfilling lives in the community. Our work is grounded in the belief that everyone deserves the opportunity to thrive, and our programs provide essential services and support to individuals and families. We are seeking an experienced Controller to join our finance team and help ensure that Cornerstone Montgomery has the strong financial systems, accurate reporting, and sound controls needed to advance that mission.

This is an opportunity for an accounting professional who wants to do more than close the books.

The ideal candidate combines strong technical accounting skills with sound judgment, curiosity, and a collaborative approach. This person will be comfortable rolling up their sleeves to solve problems while also looking for opportunities to improve processes, systems, and internal controls.
