Every 15 Minutes

On April 17 and 18 the juniors and seniors at SDHS participated in the CHP sponsored “Every 15 Minutes” program.  These two days included a mock drunk driving accident and mock memorial service. Students saw the effect that drinking and driving could have on their lives and the lives of others.  It is the hope of SDHS staff that students celebrate their prom and upcoming graduation in a safe manner in the coming days.  

Below are photos of the mock accident, mock funeral from the program. Students in the SD Video classes also created an amazing Every 15 Minutes Video.

Saints Baseball Coach Gets His 300th Win

Mike Regan, San Dimas High School’s 18-year Head Baseball Coach, won his 300th game in March against Arcadia High School. Coach Regan has led his team to four Valle Vista League titles in a row with a total of six titles in his career. He has five CIF Quarter Final Appearances, three Semi-Final Appearances, and one CIF Championship. In 2015, Regan’s Saints finished the season 31-1 and were ranked #1 in the country in USA Today.

Co-Head Coach Mark Chiappelli said, “He will say that it’s not about him, it’s about the players and his coaches on staff, but without his guidance, his trust in his coaches, his ‘old-school’ approach, his grind and desire to get every player better, his consistent coaching throughout every game we play, San Dimas wouldn’t have the program it does today.”

Congratulations, Coach Regan!

Almost 150 parents and students attended the March event, a highlight of which was a presentation by San Dimas alumna Brittany Clarke who now attends Yale University.

Additional breakout topics included the University of California and California State University systems, the NCAA, financial aid, and SAT/ACT prep.

Sammy Saint Leads the Charge

The 2015 ASB administration and Cheer Squad at San Dimas High School established a new Mascot Team comprised of six San Dimas High School Students. Now the team has a mascot costume, developed conceptually by Coach Kim Lowary and Principal Michael Kelly and constructed by Maywell Mascots, Inc. In a few short months, Sammy Saint has won the hearts of the student body, parents, city officials, and the San Dimas community. 

The 2016 Mascot Team includes Emily Basulto, Justin Grant, Asher Kocalis, Braidan Lowary, Kendra Rogers, and December Swift. Each member of the team and even guests sometimes dress as Sammy Saint at various events. The costume fits people of heights from 5’5” to 6’2” and has a fan inside the head to keep the mascot cool.

“It has been exciting to see the crowd react when Sammy appears at an event,” Coach Lowary said. “Kids love him! Most recently, Sammy appeared at the City of San Dimas Family Fitness event. He danced, posed for pictures, and ran alongside the toddler marathon.”
