Marathon Bank offers deposit products including non-interest-bearing and interest-bearing checking accounts, savings accounts, money market accounts, certificates of deposit, and individual retirement accounts; lending products such as one-to-four family residential real estate loans, multifamily real estate loans, commercial real estate loans, commercial and industrial loans, construction loans, consumer loans, home equity loans, and small business loans; and business banking services comprising treasury and cash management products, municipal banking, specialty lending, and feature-rich online banking platforms. The company, founded in 1902 through its banking subsidiary, maintains headquarters at 500 Scott Street in Wausau, Wisconsin, and operates full-service branches in Wausau, Mosinee, Rothschild, Mequon, and Brookfield. In 2025, Marathon Bancorp completed a second-step conversion of its parent mutual holding company Marathon MHC to stock form, raising approximately $16.9 million through a community stock offering of 1.7 million shares and uplisting common shares to the Nasdaq Capital Market effective April 22 under the MBBC ticker; the company also opened a new full-service branch in Brookfield in early 2024 and promoted Michelle Knopf to chief operating officer in June 2024 to bolster mortgage and commercial operations.
