First elected by Tulsa County voters in January 1995, Treasurer Dennis Semler is dedicated to and successful at providing the citizens of Tulsa County with efficient, effective and transparent service. The treasurer's office has played a vital role in Tulsa County's recognition by the Sunshine Review Project with an A+ grade for openness and transparency. As a result, Semler was re-elected in 1998, 2002, 2006 and most recently 2010 when he resoundingly defeated his opponent in the Republican primary 61% to 39%.

Semler's integrity, professionalism and dedication to ensuring that the Tulsa County Treasurer's office provide citizen's with efficient, effective and transparent services also led to recognition by treasurers across Oklahoma who elected him President of the County Treasurer's Association in 2003-2004.

As Treasurer, Semler's primary responsibility is to collect taxes certified by the County Assessor and to administer all county funds. He receives and distributes all county monies as provided by law and effectively serves as the "banker" for the county. Neither he nor his office has any control over tax rates or tax amounts.
