Dr. John A. Wittner of West Chester, PA, died on February 15, 2024. Wittner was a dentist, a legendary engineer of winning Moto Guzzi motorcycles, and a Vietnam veteran.

Wittner was well known and regarded for his virtuosity in achieving mechanical perfection both inside and outside of the dental office.

Wittner studied mechanical engineering at Lehigh University. He graduated with his Doctor of Medicine in Dentistry from the University of Pennsylvania and formed a co-partnership with Dr. Bill Deal to create the Deal-Wittner Dental Health Group.

Dr. John’s Team Moto Guzzi was born, and it progressed from dominating regional races to taking the 1984 American Motorcyclist Association National Endurance Racing Championship at the Daytona Firecracker 400, according to an article published by RoadRacing World & Motorcycle Technology on February 21.
