About the City Treasurer

Henry W. Supinski was born and raised in Wilmington, Delaware. He has a long history of service to the City dating back to 1976 when he was hired as a Legal and Economic Consultant to the Wilmington City Council. Henry held this position for nearly nine years until July, 1985 when he was appointed by the City Council to fill a vacancy in the City Treasurer’s post. Since that time he has been elected to six consecutive 4-year terms of office, and is currently in his 26th year of service as Wilmington’s City Treasurer.

Henry graduated from Salesianum High School, LaSalle University with a B.S. in Business Administration, and holds a Law Degree from the University of Baltimore.

In the Pension area, Henry has helped change just about everything. After participating in a Statewide Pension Task Force in 1990, he recommended the creation of the City’s first non-uniform contributory pension program. He also oversaw the closing of existing Police and Fire Pension programs in favor of the State’s County and Municipal Pension Program. He also recommended changing the fund’s equity exposure to the current maximum of 60 percent.

After years of study in the 1990’s, Henry, together with then Council President James M. Baker, created the City’s first ever Retiree Health Care Program for all full-time City employees on the City’s employment rolls as of January 1, 2000.
