Meet The Team

Dan Jonasz, Owner/Operator,  American Geophysics, Inc.

American Geophysics, Inc. was founded in 2012 by our Owner/Operator, Dan Jonasz, who brings over 20 years of fieldwork experience throughout the country, and specializes in providing GPR services to industrial, commercial, and residential clients in the environmental, engineering, and construction fields. Dan is a US Airborne Veteran, making AGInc. a Service-Disabled Veteran-Owned Small Business registered with local, county, state, and federal government databases.

Dan has instilled and educated his team of technicians not only in the classroom but with real-time applications, experiences, and situations. With “SAFETY” as one of our most important and primary goals, AG Inc. wants its own employees, as well as all other members of an active job site to arrive and return safely from each day. We strive to not only keep everyone safe on-site while we are present, but also with our reporting, in case the site or project is revisited in the future.
