Coach Sergio has been in the water since the age of seven, when he first discovered the thrill of racing down the lane. He joined the Latin Swim Club at 10 years old and spent the next four years growing as a swimmer and teammate, building a strong technical foundation that would carry him through his high school and college careers. At Saint Patrick High School, Coach Sergio continued to sharpen my sprinting skills, bringing intensity and focus to every practice. He went on to swim his freshman year at Augustana College, where he competed at the collegiate level and embraced the commitment required to race against some of the best. Coach Sergio’s favorite event has always been the 50 freestyle, a flat out sprint where every hundredth of a second counts. He loves the swimming community and truly values being a part of it, from the pool deck to the cheers at finals. Coach Sergio is passionate about helping young athletes develop their strokes, their confidence, and their love for the sport, and he believes in leading by example while pushing swimmers to discover just how fast they can go.

Coach Bill Sindewald believes water polo can change lives. With more than 20 years in the sport as both a player and competitor, he brings experience, energy, and genuine passion to his role as Head Coach of Roman Water Polo. A former All-State player at Carl Sandburg High School, Coach Bill went on to serve as captain of the University of Iowa Water Polo Club and continued playing, coaching, and mentoring athletes at Augustana, Carl Sandburg, and DePaul.

Coach Bill believes sports teach far more than athletic skill — they build confidence, resilience, teamwork, and character. His philosophy is simple: sports is life, and life is sports. Outside of coaching, he stays active in the swimming community as a member of the Chicago Smelts and through open-water events such as Big Shoulders and the Chicago River Swim, which support ALS research and youth swim programs. He is proud to help Roman Water Polo grow into a place where athletes can develop as both players and people. For Coach Bill, there is nothing more rewarding than helping kids find their confidence.
