Our People
Tim Unnerstall, CPA
Tim Anthony Unnerstall, C.P.A. (not Timothy) is a life-long resident of Washington, Missouri. He attended St. Francis Borgia Grade School and High School and received Associates Degrees from East Central College in Accounting and Computer Science. He received his Bachelors Degree in Business Administration from the University of Missouri - Saint Louis and was granted a certificate as a Certified Public Accountant by the Missouri State Board of Accountancy in June 1990.
While working to fulfill the experience and apprenticeship requirements for certification, Tim went to work for the firm of Maurice L. (Moe) Unnerstall, C.P.A. Moe’s father and Tim’s father’s father were brothers. Moe’s mother and Tim’s mother’s mother were sisters. This made Moe and Tim double-first-cousins-once-removed.
During the time Tim work for Moe, Moe decided to phase into retirement. At around that time, Tim’s nephew Steven (Steve) was completing his own certification requirements. As Moe’s career was winding down, Steve was able to join the firm and help carry the load.
Tim continues to be a member of St. Francis Borgia Parish. He is very active as the Executive Secretary of the Rotary Club of Washington, one of Washington’s premier service organizations. He serves as Treasurer of the Exceptional Equestrians of the Missouri Valley, Inc., an organization providing therapeutic horsemanship experiences to individuals with a variety of disabilities.
He serves on the board of the Washington Missouri Redevelopment Corporation and the Washington Civic Industrial Corporation. As a past chairman of the Washington Area Chamber of Commerce, he is a Chamber Ambassador. He also serves on the Community Advisory Board of the Bank of Washington.

Our History
Unnerstall and Unnerstall, CPA, P.C., began in 1958 with general accounting services for business and individuals. This developed into strategic planning for individual wealth maintenance, minimization of tax liabilities for individuals and corporations, payroll and consulting services. We believe in "old school" principles, but we also believe in keeping up with the needs of individuals and businesses in this rapidly changing world. In 1991 Tim took the business over from a retiring Moe Unnerstall and brought on Steve as a partner in order to help with the rapidly expanding workload.
