"Super Saturday" Showcases

the Full Spirit of Justin-Siena


Spring at Justin-Siena High School is always a whirlwind of activity, and this past weekend offered a powerful reminder of just how extraordinary the breadth of talent and opportunity within the Justin-Siena community truly is.

From Friday, through Sunday, May 1-3, our students demonstrated excellence across athletics, the arts, service, and leadership in what could only be described as a “Super Saturday” weekend—one that reflected Justin-Siena’s deep commitment to both high-quality and award-winning co-curricular programs, while celebrating the diverse passions of our students.


The weekend began Friday with Boys Varsity Lacrosse participating in the VVAL Championship game. On Saturday, Boys Varsity Baseball took the field on one of the sport’s grandest stages, Oracle Park in San Francisco, competing in the High School Showcase proudly representing the Braves. Later that same day, students and families gathered on campus for the annual KA-IN NApa Valley event, raising awareness and funds for DISP and highlighting the school’s commitment to service, inclusion, and community impact. Meanwhile, Justin-Siena’s talented performing arts students took center stage to present their Spring Concert, The Sounds of Cinema, delivering a performance that showcased months of dedication, artistry, and collaboration.


The weekend concluded on a high note on Sunday evening with Justin-Siena’s musical theatre production of Big Fish earning top honors at the Sara Bareilles Awards at the Orpheum Theatre in San Francisco, winning Best Overall Cast Performance, further cementing the school’s reputation for theatrical excellence.


As the excitement of the weekend gave way to Monday morning, students shifted seamlessly back into the classroom for the start of AP Exams—an apt reminder that excellence at Justin-Siena extends beyond the field and stage into the realm of academics as well. With graduation preparations now underway for the Class of 2026, this remarkable weekend served as a felicitous snapshot of the vibrant, well-rounded student experience that defines Justin-Siena.

FOUNDERS DAY!

ALLHEART Highlights

"Breathe, just breathe. 

I hear the clear, cold sound of skates against ice sliding all around me. I open my eyes, letting the sight of the ice rink settle into view. There is a graceful woman on the ice in front of me, spinning in dizzying circles that give way to thunderous applause."


Congratulations our very own freshman, Olivia Elges, for winning first prize in the 2026 High School Jessamyn West Creative Writing Contest. Vee submitted creative writing that she worked on this year in Honors English 9.

Coinciding with our Holy Week Liturgy, we celebrated Grandparents Day, a touching tradition that brings together family and faith.

Living in the spirit of our Founder, St. John Baptist de La Salle, we honor our educators this and every week! National Teacher Appreciation Week recognizes their dedication to inspiring curiosity and learning through their vocation.

This year, our annual Inclusion Week Cultural Food Fair also featured a "spring cleaning" clothing pop-up shop. Led by our Environmental Club, the shop aimed to raise money for "Change For Our World," supporting our twin school in Ethiopia. Thank you to everyone who donated and participated!

Thank you to Mare Island Brewing Co. and Sentivo Winery for hosting our recent J-SPA Mixers!

It is not every day that a dog steals the show as a guest speaker! Forensic scholars welcomed Mocha, a specially-trained accelerant detection K9, and Marshal Charlie Elder, arson and bomb investigator with Cal Fire, to learn more about accelerants and arson and bombing investigations.

Open to students and families from all over the valley, College Fest 2026 welcomed 30+ institutions to our campus. This collaborative opportunity enabled students to learn directly from the source about admissions requirements, campus life, and more!

The Class of 2026 has started the class year daily countdown to graduation! For some reason it seems like they start earlier and earlier every year...

For over 20 years, Justin-Siena's Religious Studies scholars have been going to San Francisco's St. Anthony's Church as a part of our charism's call to serve.

Advanced Studio Art scholars have been invited and inspired to participate in the "We The People" Community Quilt Project for Northern California! The project allows students to weave our Lasallian values into artistic expression. Nearing completion, we cannot wait to see how our creation turns out!

Athletics

A record 11 senior student-athletes, from 8 programs, were recognized during our annual

College Athlete Recognition Ceremony!

As the 2025-2026 school year comes to a close, the student-athletes, coaches, and supporters of the Justin-Siena High School Athletics Department have much to celebrate! Braves teams have proudly represented the school, demonstrating resilience, sportsmanship, leadership, and competitive excellence, while bringing success across multiple programs. 


The Varsity Boys Tennis team continued its dominance capturing both the Vine Valley League regular season title and the VVAL Championship Tournament, marking the program’s fourth consecutive sweep of both championships. Completing an outstanding season, Ryan P.’27 was named VVAL Player of the Year, while Sammy L.’26 and Henry E.’27 captured the VVAL Doubles Championship. Additional All-League honors were awarded to Grant D. N.’28 and Luc B.’28 in singles, along with doubles team Alex M.’26 and Andrew B.’28. The Braves now advance to the NCS Team Tournament and the NCS Singles/Doubles Championships, with Ryan, Sammy, Henry, Grant, Alex, and Andrew all earning NCS bids.


The Boys Golf team also delivered an exceptional season, finishing undefeated en route to the VVAL Championship. The Braves posted an impressive team score of 379 at the league championship tournament. Jack K.’26 earned low medalist honors with a 2-under-par 70, followed closely by Alex K.’29 with a 71, while Cade S.’26 finished fourth overall with a 75. Jack, Alex, Cade, and Nic P.’26 all earned Individual All-League honors. The Braves now look ahead to the NCS Division II Championship, where Jack, Alex, Cade, and Nic, and Jack O’M.’28, will attempt to defend the program’s 2025 NCS Championship title.


In the pool, the Varsity Girls Swimming team placed third overall at the VVAL Championships, while the Varsity Boys Swimming team earned a runner-up finish. The Braves will continue their postseason journey at the NCS Swimming Championships on May 8. Congratulations to Aiden F.’28, Jacob I.’26, Nikolas K.’27, Peyton R.’27, Savannah H.’27, Elise I.’29, June K.’27, Eliza W.’26, Clare C.’26, Rafael E.’26, and Shane F.’28 on qualifying for NCS competition.


For baseball and softball, both have wrapped up their regular seasons and project to be high seeds in their respective NCS divisions! Off the courts, off the field, and out of the pool, 117 out of 204 spring varsity student-athletes, received NCS Scholar Athlete and NCS President’s List for academic GPAs of 3.5 - 4.0. 


Throughout the year, across every sport, Braves teams competed with pride and determination, achieving success both in league competition and postseason play. From championship performances to individual accolades and continued advancement into NCS competition, Justin-Siena athletics continues to build a culture centered on excellence, commitment, teamwork, and growth.
