"For me to give back to the sport that has given me so much, I have always thought about being a high school coach and I think this is a good start. Where I can come in, and ease into and learn from the coaches and kids and hopefully they can learn a little bit from me too," Koppen said.
The two-time Super Bowl champion lives in Smithfield with his wife, Amber Van Eeghan, the daughter of former Patriot Mark Van Eeghan.
"Once you get in Rhode Island you don't get out, so we are here for the long haul and I am excited about it. It's a great state, great community and we are just putting down roots," Koppen said.
As for the Hendricken players and coaching staff, they look forward to adding a former Pro Bowl player to their team.
"It's exciting to have an opportunity to learn from him, somebody who has obviously played at a very high level and has learned under some great coaches. It is hopefully going to be a win-win for everybody," said Hendricken coach Keith Croft.
