County Executive John “Johnny O” Olszewski, Jr. is a lifelong Baltimore County resident who

believes in the power of public service and giving back to a community that has done so much

for him. He is a graduate of Sparrows Point High School, earned his undergraduate degree from

Goucher College, a master’s degree from The George Washington University and his PhD in

Public Policy from the University of Maryland Baltimore County.

In 2006, Johnny was elected at age 23 and re-elected four years later as the top vote getter to the

Maryland House of Delegates from legislative district 6, a position he held for nearly nine years.

His work earned him a reputation as a “rising star” of Maryland politics – and breathed new life

into the abandoned steel mill in his hometown.

In the legislature, Johnny served as the Chairman of the Baltimore County House Delegation and

was youngest person ever elected to that position. In that capacity, he helped lead unprecedented

progress for the County in areas such as economic development and school board reform. As a

staunch advocate of working families, Johnny led the charge on earned sick leave, raising the

minimum wage and offered a critical vote in securing Marriage Equality in the State of

Maryland.

Today, County Executive Olszewski is focused on fighting for our schools, creating a more

transparent government and building a better Baltimore County for all residents.

He lives in Dundalk with his wife, Marissa and daughter, Daria.
