In this edition of our “Voices of RSPA” series, Racquet Sports Professionals Association (RSPA) member and Hall of Fame inductee Jack Groppel reflects on his journey in the industry, the value of certification, and the relationships that have shaped his career. Longtime RSPA member John Weil sits down with Jack to explore his story. John is a 15-year teaching professional, a 46-year RSPA member, a Midwest Division Hall of Fame inductee, and has spent 33 years in the tennis industry in sales.
John Weil: Jack, my first question for you is: Give me your name, where you are, your current position in business, and what you’re doing.
Jack Groppel: I’m Jack Groppel. I now live full-time in Estero, Florida. I’m officially retired, but I’m still an author and continue to give presentations. I’ve stepped away from corporate work, but I’m far from done.
John Weil: And how long have you been a member of the RSPA?
Jack Groppel: Between 40 and 45 years. Bob Kust tested me in — it was either 1981 or 1982. When I was inducted into the Hall of Fame, I mentioned Bob in the tribute video.
John Weil: Looking back now as a member, what was your motivation for joining the RSPA?
Jack Groppel: My story is a little different. I was building my reputation as one of the first sports scientists studying the game. I wanted to understand coaches’ needs and contribute to their growth. Joining the largest certifying body felt like the right move. I was coaching the men’s tennis team at the University of Illinois and preparing to step down to travel with tour players. I knew I needed to be part of this organization.
John Weil: What kind of benefits have you perceived from your membership?
Jack Groppel: The biggest benefit was networking and building my reputation through speaking and writing. I wrote for Advantage Magazine and had the “Ask the Professor” column for 25 years. That gave me a platform to connect with like-minded professionals and help answer their questions.
John Weil: I know you’ve been involved in many areas of the RSPA. What additional roles have you held — board positions, conventions, testing?
Jack Groppel: I served on the national board from 2007 to 2011 and was a vice president. I attended every convention for about 30 years and spoke at every division conference. I was very actively involved.
John Weil: Did you meet individuals through RSPA who’ve remained in your network and inspired you.
Jack Groppel: Absolutely. I’ve met thousands of people through my travels. In 1986, I represented USPTA in Australia and did clinics for two weeks. I’ve built lifelong friendships through those experiences. For example, I met Rick Vetter when I played at Illinois and he played at Michigan State. Rick introduced me to Tim Gullikson in 1982, and Tim became one of the first pros I worked with. That relationship was incredibly meaningful.
John Weil: I know you’re still very involved. What are you doing now, and do you have any goals moving forward?
Jack Groppel: I’m still teaching — I volunteer to coach the ladies league teams in my community. I continue to write, and my memoir comes out in January. I’ll probably write another book. The day I die is the day I stop working.
John Weil: My last question: What advice would you give to a prospective or new member about the RSPA?
Jack Groppel: Get involved. Don’t sit on the sidelines. Tennis is an individual sport, and we get good at taking care of ourselves — but this is about community. Be active in networking and help the organization grow. It’s easy to just pay your dues, read the magazine, and attend a conference. But when you get involved, you learn more. Teachers learn more when they teach. Students ask great questions, and that helps us become better professionals.
Jack’s story is a powerful example of how science, service, and connection can shape a career in racquet sports. His legacy continues to inspire professionals across generations.
