The Tidemark Federal Credit Union Foundation


Through our charitable foundation, we seek opportunities to support disadvantaged children and families in the communities we serve. Whether it's food, clothing, medical aid or other needs, the foundation exists to provide assistance through food banks, camp programs, school supply programs and financial education programs.

We've partnered with several area middle schools, as well, to focus on an underserved age group in our communities, and we're ecstatic about the support we receive from school leaders.
