Bill Ronayne, the owner of West Chester-based Brandywine Valley Heating & Air Conditioning, is taking to the skies for a cause dear to his heart.

On Friday, Ronayne, a full-time businessman and part-time thrill-seeker, will rappel 29 stories down the Brandywine Realty Trust’s Commerce Square Building, an iconic skyscraper in Center City, Philadelphia.

The adventure is part of the Philadelphia Outward Bound School’s annual high-adrenaline fundraiser that reflects the school’s mission to change lives through challenge and discovery.

Participants like Ronayne bravely mirror what POBS’s outdoor education programs encourage young people to do every day: challenge themselves, discover untapped potential, and use it to make positive change in the world.

“I’m going over the edge on an amazing adventure for an amazing cause,” said Ronayne, also a volunteer firefighter for Fame Fire Company on Rosedale Avenue. “I’m asking that people please consider donating to help support the school’s mission and educating future leaders right here in the West Chester area.”

Ronayne’s goal is to raise $2,000, and he needs your help. Click here to contribute and make Bill’s journey over the edge possible.
