Jeffrey deCoen

My first interest was in the Legal Profession, having studied Pre-Law in College. This led me into the courtrooms, and was able to learn and obtain wonderful experience of so many things. Then I turned to LIFE (Living Intentionally For Excellence}. Here I was able to develop what is truly needed in the field of leadership. Being able to associate with two of the most renowned leaders in the world provided me once again with great insight.

My true passion has always been within the Golf Industry. Golf is said to be a “Game of a Lifetime,” and boy does that ever hold true. I am certified through the United States Golf Teachers Federation. I have taught many Professionals, Amateurs, and children (through clinics and camps), and looking forward to offering my experience to the York community. I have been in this wonderful profession for many years. I have had a great opportunity to walk countless fairways and read many greens for some of the best “professionals” upon the LPGA Tour. I have been able to compete, and record some championships, and now the road has led me to Indoor Golf & Training Center York.

Please welcome Jeff to York Indoor Golf and make sure to reach out for any Golf Instruction and Club Fitting needs.
