John B. Riordan became the Supervisor of the Town of North Hempstead, N.Y., on Oct. 7, 2013, to serve the unfinished two-year term of Jon Kaiman, who resigned to become the Special Adviser on Superstorm Sandy Relief to Gov. Andrew Cuomo as well as Chairman of the Nassau Interim Finance Authority (NIFA). He left office on Dec. 31, 2013 and was succeeded by Judi Bosworth, a Democrat, from Great Neck, New York.
Riordan, 70, a Democrat who had been Town Attorney for the past year, was elected by a vote of the Town Council, which split along party lines, 4 to 2, on Oct. 2. Riordan was not a candidate for the post in the election of Nov. 5, 2013. Bosworth defeated Republican Town Councilwoman Dina DiGiorgio in the election.
The Town of North Hempstead, with 235,000 residents, is the one of the largest municipal governments in the U.S.
Riordan, a longtime resident of Williston Park, New York, served as Nassau County Surrogate from 2001 to 2010 but was narrowly defeated for reelection by Republican Edward W. McCarty III. He then returned to private law practice. Riordan lost a bid for N.Y. Srate Supreme Court in 2011. Previously, Riordan was elected to the Nassau County District Court, where he served as a judge from 2004 to 2001.
Riordan earned his law degree from St. John's University in 1968, two years after receiving a B.A. from Hofstra University. Subsequently he was in private practice until becoming a judge. He was a member of the East Williston Fire Department for 16 years. He is a member of the Nassau County Bar Association and the Catholic Lawyers Guild.
