Jack Bañuelos was a Pinole Seal for 8 years. He currently attends DVC and is on their water polo and swim team. 2022 was Jack’s last season on the Seals and he enjoyed providing his teammates with helpful insight and tips when they asked. After seeing them reach their goals and get the times that they wanted, it really inspired him to want to be a coach. This will be Jack’s third season as a coach.
