About us

We have three important things in common, that combine to allow us to develop high-quality software to support golf engineering: we have engineering educations and backgrounds, years of professional experience in software development, and a passion for golf and golf technology.

Frank Schmidberger is a mechanical engineer, located in Ravensburg, Germany. He has been working in software development for more than 40 years now. Frank started playing golf in 2001. Beside the game of golf itself, he is interested in every technical aspect of it. Frank is currently working in Munich, Germany. He is married to Duscha and has two children, a daughter named Selina and a son named Daniel.

Dave Tutelman has degrees in electrical engineering from the City College of New York and the Massachussetts Institute of Technology, and postgraduate work in computer science at the University of Pennsylvania. When he retired from Bell Labs in 2002 after a 40-year career there in engineering and software development, he turned his efforts to golf club technology, a longtime hobby. He and his wife Rochelle have raised two sons. They live at the Jersey Shore in the United States. For more about Dave, see his web site, which has articles from his golf club research.

Believe it or not, Frank and Dave have never met face to face, nor even talked on the telephone. The TrajectoWare collaboration has been completely via the Internet.
