Our Work Speaks for Itself

Our Broad Street Market, which is a staple of our community, was really struggling due to a fire that ravaged one of their two buildings. Money was an issue. Shayne Homan from McClure Company reached out and offered to help. It was so nice to have an organization like McClure – professional, Union, and local – step up. They offered to outfit the entire structure for free. It saved Harrisburg taxpayers more than $70,000 and helped us get closer to bringing the market back for the local community. On top of this, they are working on a brand-new HVAC system for our public safety building. The experience that the City of Harrisburg has had with McClure Company has been exemplary. Shayne and his team have always a wonderful job for us and we’re grateful.

- Wanda Williams, Mayor of Harrisburg
