OSB Community Bank originated in 1907 in Onsted, MI. We have since evolved from a one town, one location Bank to three locations, with our Founding Lenawee County office in Onsted, one location in Brooklyn, one in Ann Arbor, servicing customers primarily in these market areas.
We are a Community Bank with a team who take the word “Community” very serious. Our staff and directors live in the communities we serve and are locally-minded and involved. We realize that banking is more than processing a deposit or making a loan. It is volunteering time to various community organizations and committees, donating much needed resources to community programs, as well as being consultative partners to our clients.
OSB Community Bank is truly “more than a bank” and we believe that investments made in our community today will lead to a stronger tomorrow and a better place that we can all be proud to call home.
