"Words cannot express how excited I am to be named the head softball coach at Kalamazoo College," Duimstra said at the time of her hire. "I feel extremely fortunate to have the opportunity to be a part of such a prestigious institution.

"I've seen firsthand the growth the Kalamazoo softball program has shown over the past few years. I'm looking forward to building on that progress and advancing this program to new heights. I believe this program has great potential and it's my goal to turn it into an MIAA, regional, and ultimately a national contender while maintaining the academic excellence that is expected at Kalamazoo College."
