John Schon, President

John brings a customer-centric focus to Tobin Testing from his years of experience as an owner and operator in the restaurant industry. While managing a commercial and timberland real estate portfolio, John became keenly aware of emerging unconventional plays in the Appalachian basin and the regional economic impact. It wasn't long before John realized there were significant vacuums in the local business community related to the growing industry. John went on to assemble a team of business leaders and scientists to provide local analytical services to E&P companies, their supply base, landowners, and partners.

Now operating the lab, John sustains a hands-on approach, working intimately with staff and clients to tailor services to specific client requirements. John has the breadth of knowledge, experience, and leadership to provide the quality technical analyses and responsive service required to meet our clients’ needs.
