Onondaga County Executive’s Biography
Joanne M. Mahoney

Elected in November 2007, Joanne M. Mahoney is the first woman to serve as Onondaga County Executive.

Growing up in Syracuse, Joanie Mahoney graduated from Corcoran High School before graduating from Syracuse University's School of Management and S.U.'s College of Law.

After spending time in private practice, County Executive Mahoney worked for five years as a criminal prosecutor in the District Attorney’s Office before being elected Councilor-at-Large in the City of Syracuse where she served a four year term.

In 2008 Joanie led Onondaga County to work toward a greener, more sustainable community culminating in “Save the Rain”, a comprehensive stormwater management plan developed to reduce pollution to Onondaga Lake. In 2011, Onondaga County was recognized by the EPA as a green infrastructure partner for its work on “Save the Rain” and Governing Magazine named the County Executive a “Public Official of the Year”.  In April, Onondaga County is to be awarded the U.S. Water Prize by the U.S. Water Alliance.

County Executive Mahoney has also placed a tremendous emphasis on literacy and education guiding the County’s partnership with Say Yes to Education, which will increase graduation rates and make college a possibility for many city students. 

County Executive Mahoney is also committed to working collaboratively with her government partners.  In 2010, then Governor-Elect Andrew Cuomo asked County Executive Mahoney to serve as co-chair of his transition team and in 2012, he appointed Joanie to serve as a Trustee for the New York Power Authority.  In the aftermath of Superstorm Sandy, Governor Cuomo asked County Executive Mahoney to serve on the Moreland Commission, which is tasked with investigating New York’s power utilities’ preparation and response to the major storms that have devastated communities in the State of New York over the past two years

In November 2011, Joanie ran unopposed and is currently serving her second term as County Executive.

Joanie Mahoney and her husband Marc Overdyk have four sons and reside in the Town of Dewitt.
