Personal Background: Mark graduated from Messiah University with a Bachelor’s degree in Marketing in 2008.

However, seeking new opportunities, Mark relocated to San Francisco, California, where he entered the online and web industry. During this time, he worked as a technical recruiter, matching candidates with leading companies such as eBay and StubHub.

Drawn by his love for the mountains and the rural charm of Pennsylvania, Mark eventually returned to his hometown, where he currently resides with his son. In his free time, Mark enjoys a variety of activities, including playing guitar and participating in sports such as soccer, basketball, and football.
