Jeff is married to Dr. Yingling and together they have operated and managed Mason-Dixon Endodontics since 2002. Jeff is the Business Manager and recently took on the role of our Professional Relations Manager to ensure our referring doctors and practices know they matter and that we are taking excellent care of their patients. Jeff was the flexible working parent over the years, but the Yingling’s three children are now independently mobile, so he is back in the office and on the road visiting offices. He is a retired Air Force Lieutenant Colonel and served in the Persian Gulf War. Jeff graduated from West Virginia University and earned his master’s degree at Webster University while stationed in Iceland. He was assigned to bases in Texas, North Carolina, and Iceland before he met Dr Yingling at Aviano AB, Italy.

He has volunteered for numerous organizations over the years including the Gettysburg Youth Soccer Club, Gettysburg Warriors Athletic Booster Club, Ski Liberty Mountain Safety. Make sure you wave to Jeff in the hallway – he will probably be on the phone!
