John grew up in the shadow of a steel mill.  He saw firsthand the detrimental effects the mill’s closure had on his friends and family.  But like so many in Baltimore County, he didn’t give up, he went to work.  John was the first in his family to attend college. After graduating from Goucher College, he returned home to be a social studies and special education teacher in the community at Patapsco High School.

In 2006, John 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.  Today, the Port of Baltimore is thriving and Tradepoint Atlantic promises 10,000 news jobs in Baltimore County.  In the legislature, John 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 stanch advocate of working families, John 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.

In addition to his responsibilities leading the 21-member Delegation in the state legislature, he served on the House Economic Matters Committee, Maryland’s P-20 Leadership Council, the Maryland Business Climate Workgroup and as Chair of the Banking, Economic Development, Science, and Technology subcommittee.

He is a former student member of the Baltimore County Board of Education, a 2010 graduate of Leadership Baltimore County and was recognized as one of the Daily Record’s “Top 20 in their 20’s” in 2012.

John is a proud product of the Baltimore County school system, graduating from Sparrows Point High school before attending Goucher College and The George Washington University. Johnny is currently pursuing his PhD in Public Policy (concentration in Public Administration) at the University of Maryland, Baltimore County. 

He is an active philanthropic and economic development leader, and serves as a member of the Business Network for Offshore Wind board as well as President of the Board of the Community College of Baltimore County’s Dundalk Foundation. Johnny is currently working in the private sector at SAS Institute, where he partners with governments to help prevent fraud, enhance public safety, improve program performance and enable greater transparency. 

Johnny lives in Dundalk with his wife Marisa and their daughter Daria.  The Olszewski family is active in their church as members of Lovely Lane United Methodist Church and maintain strong ties as volunteers in their community and across Baltimore County.
