Sacred Heart Cathedral Athletics is pleased to announce Mackenzie Riddle as the new Head Girls Lacrosse Coach. 

Most recently, she served as the head varsity girls lacrosse coach at Foothill High School in Pleasanton, where she led the Falcons to the 2026 North Coast Section Division II Championship. Foothill finished the season with an impressive 15-7 overall record, capped by an 8-7 victory over University in the championship game. Riddle brings a strong combination of coaching experience, teaching expertise and a passion for developing student-athletes both on and off the field. 

A graduate of the University of Oregon, where she earned a Bachelor of Science degree, Riddle currently teaches middle school physical education at Westborough Middle School. Her connection to lacrosse began at Amador Valley High School before continuing at Oregon, where she played club lacrosse.

"What excites me most about this opportunity is getting to work with girls who are passionate about the sport of lacrosse and turning it into an experience they will enjoy and remember forever," said Riddle. "The Sacred Heart Cathedral mission aligns so closely with my coaching style."

Riddle's coaching philosophy emphasizes a love of the game, sportsmanship and personal growth. Her vision is to create an experience where student-athletes enjoy competing, develop meaningful relationships and learn to be good teammates and good people.

"We are excited to welcome Mackenzie to Sacred Heart Cathedral," Athletic Director Margi Beima said. "Her championship experience, background as an educator, and commitment to developing young people make her an outstanding addition to our coaching staff. Just as importantly, her values and philosophy are a wonderful fit for our community."

Riddle's commitment to service reflects a strong connection to Sacred Heart Cathedral's Lasallian and Vincentian traditions. She completed more than 650 hours of community service during her youth, demonstrating a commitment to giving back to the community.
