GreenState exists to serve its members.

Our “members first” philosophy has led to a national rank by independent research firm Callahan & Associates for Return of Member (ROM). This measures how effectively a financial institution returns its profits back in the form of better rates on deposits and loans. For nearly a decade, GreenState’s ROM rank has consistently been in the top 1% up against more than 13,000 banks and credit unions nationwide.

GreenState exists to serve the community.

We volunteer time and donate funds to support the local organizations and charities that help our communities thrive. We provide financial education for area schools and businesses to help residents grow and make smart money decisions.
