Isaac Grombacher of Nitro Swimming is the head coach of Sean Grieshop.
Grieshop won his first National title in the men’s 400 IM, dominating the field by over three seconds. The future Cal Bear stopped the clock in 3:44.69, just off his personal best of 3:44.30.
Grombacher noted how he’s pleased with where Grieshop is despite his busy fall schedule of traveling to recruiting trips and the World Cup Circuit. He also said Grieshop is focused on his goal of qualifying for the World Championship team and said that he loves working hard.
