Meet the Team


Mark Tomlinson
General Manager

Mark started with York Aviation in 1992 working part time and rejoined the team in 2003 after serving as an Avionics Technician in the United States Navy.  While in the Navy, he graduated aviation electronics schools at both NAS Millington, TN and NAS Miramar, CA, and went on to troubleshoot F-14, F/A-18, S-3B and E/A-6B avionics aboard the USS Dwight D. Eisenhower (CVN-69) during one overseas deployment cycle.  He earned the Navy-Marine Corps Achievement Medal, Aviation Enlisted Warfare Specialist designation and logged one trap in a C-2 Greyhound.  Mark also has “big airport” FBO experience, having worked the busy ramps at both Las Vegas McCarran (KLAS) and Harrisburg International Airports (KMDT). So if you show up in anything from a Cessna 150 to a Boeing 767, you can rest assured Mark has the experience and knowledge to service your aircraft with precision and timeliness — to ensure you and your passengers have a pleasant stop in York, PA.
