Getting the Gold!

Justin-Siena Honored with AP Access Award


In February, Justin-Siena was named to the 2026 Advanced Placement® (AP®) School Honor Roll, earning Gold level distinction for its success in student achievement and commitment to expanding access to rigorous, college-level coursework.


In addition to the Honor Roll recognition, the school received the AP Access Award, which highlights efforts to increase participation among low-income and underrepresented students. At Justin-Siena, the percentage of students in these categories taking at least one AP Exam before graduation meets or exceeds that of the overall student population, reflecting our school’s dedication to equitable access to advanced learning opportunities.


The AP School Honor Roll recognizes schools that cultivate a college-going culture, expand access to AP courses, and equip students with the skills needed for college readiness and long-term success. Justin-Siena currently offers 15 AP courses across a variety of disciplines, with 31 course sections available to students. The program is supported by intentional academic preparation, faculty mentorship, and the school’s broader mission to educate the whole student.


This recognition reinforces Justin-Siena’s commitment to our core principles. We work to ensure accessibility to quality education for all students. By expanding AP opportunities and supporting students from diverse backgrounds, Justin-Siena’s AP program exemplifies how intentional preparation, dedicated faculty, and equitable access work together to make high-level academic achievement a reality for all members of the student community.

It's titration season again in AP Chemistry! Titration is commonly used to fine tune dosing in the pharmaceutical industry, during wine manufacturing, for environmental monitoring, and more! Last week we practiced neutralizing weak acids with a strong base. For our experiment, a light pink solution was the end goal. Dark pink signals over titration. Luckily, AP Chemistry is just the starting point of many scientists' titrations- as practice makes perfect! 

Hosted at Carabao Filipino Eatery celebrating International Women's Day, our exclusive "Women In Wine Luncheon" CRAB FEST Buy-a-Spot was a success! Special appreciation to Harvest Duhig, Duhig Wines; Angelina Mondavi '00, Aloft and Dark Matter; Hailey Trefethen '04, Trefethen Family Vineyards; Jenny Wagner '06, Emmolo Wines and Caymus; and the Gonzales family!

You are never too old to have fun! Our seniors were treated to a "Kindergarten Day" festival where they were invited to recreate and wistfully reimagine their first days of school fashion styles, play nostolgic playground games, and reconnect with their kindergarten classmates.

Enjoy a student design brief on a recent Honors Principles of Engineering "Bridge Project."


This project involves the use of the Bridge Designer 2016 software. This application allows users to build a bridge with joints and members over a gap and then test its integrity when a car is driven on it. The members can be adjusted to change their thickness, material, or cross-section, whether they are hollow or solid. These changes and the number of members can affect the weight and cost of the bridge, which is calculated by the program. The software allows for additional customization of the initial situation, but for this project, it starts with a high-strength concrete deck, arch abutments, and some pre-set joints in a straight line along the deck. The car’s weight is set to 480,000 N.


The project goal is to build a bridge that holds under the car’s weight and fulfills the following requirements:

● Each member cannot exceed a compression or tension force/strength ratio of 25%. These numbers are calculated by the software itself.

● The bridge’s structural efficiency must be greater than 110%.

-Structural Efficiency = Car’s Weight (480,000 N) / Bridge’s Weight * 100%

● The design efficiency must be less than $3000/%. -Design Efficiency = Total Cost / Structural Efficiency

Congratulations to our Class of 2027 Student Body Co-Presidents: Dylan Holcomb, June Kelly, and Ava McGinty!

Season wrap up 

The Varsity Boys Basketball team at Justin-Siena High School wrapped up a strong 2025–26 campaign highlighted by a league tournament championship and a return to postseason play in the CIF North Coast Section Boys Basketball Championships.


After navigating a competitive regular season schedule, the Braves caught momentum late in league play to end the regular season with a 5-game winning streak. Justin-Siena advanced through the bracket and defeated Casa Grande High School 52-41 in the championship game, securing the program the VVAL tournament title.


Following the league championship, Justin-Siena earned a spot in the CIF North Coast Section Division II playoffs, receiving the No. 15 seed in the tournament bracket. In the opening round of the postseason, the Braves were set to face off #2 seed, Cardinal Newman. The team ended their season 17-12. 


Between their strong league finish with an overall record of 10-4, VVAL tournament championship title, and playoff opportunity, the Braves capped off another impressive season. Although they say goodbye to 4 of their seniors, with many of the bench returning and lower level students preparing to level up, the team looks hopeful for the 2026-27 season to add another chapter to the growing tradition of success for Justin-Siena boys basketball.

While the team found success on the field, the season was also marked by meaningful community engagement. During their Women in Sports Night, the Braves hosted youth athletes from across Napa County and collected donations for the Napa County chapter of Girls on the Run, raising awareness and support for programs that empower young girls through sports and physical activity. The evening brought together student-athletes, families, and community members in celebration of female participation in athletics.


The program also partnered with the Napa/Vallejo Dutch Bros Coffee team to host a Dutch Bros Night in celebration of Women in Sports Week.

Wrestling 

VVAL Awards

  • Moana M.’28 - First Team


The Justin-Siena wrestling program wrapped up an impressive season with determined performances at the NCS Division III Championships at Clear Lake High School, and the North Coast Section Championships the following weekend. Throughout the year, Braves wrestlers demonstrated resilience, growth, and a commitment to competing at a high level against some of the toughest competition in the region.


At the NCS Division III Championships, the Justin-Siena boys team placed 8th out of 24 teams, highlighted by several podium finishes. Jayden W.’27 captured a 1st-place finish, while Rian A.’28 placed 3rd, earning both wrestlers qualification to the NCS Championships. Additional top finishes included Frank R.’29, Ryder S.’27, and Marcus S.’28, each finishing 6th, and Anthony C’28 and Yohaan M.’29, who both placed 8th. The Braves were also represented by Arlo V.-M.’29, Nagi H.’26, Benjamin F.’27, Gabriel E.’27, and James B.’29, who competed with determination throughout the tournament.


On the girls side, the Braves placed 10th out of 22 teams, led by standout performances from Moana M.’28, who finished 2nd, and Sophia M.-M.’29, who earned 3rd place. Both athletes advanced to the NCS Championships, continuing an impressive season for the Justin-Siena girls wrestling program. Sophia, Moana, Rian, and Jayden all advanced to the NCS Championships at James Logan High School, where they competed against the best wrestlers in the section. Freshman Sophia, finished her first varsity season with an 18–16 record, earning her NCS berth with a 2nd-place finish at the VVAL Championships and 3rd at the NCS D3 Championships. Although she went 0–2 at NCS, she faced strong opponents, including the eventual 7th-place finisher, gaining valuable experience that will help shape the rest of her career.


Sophomore Rian concluded his season with a 19–16 record, returning to the NCS stage after qualifying with a 2nd-place finish at VVAL and 3rd at the NCS D3 Championships. While he finished 0–2 at NCS, his experience competing at the sectional level will serve as motivation for continued growth.


Sophomore Moana posted an impressive 13–6 record after returning from an injury-shortened season last year. She qualified for NCS by winning the VVAL Championship and finishing 2nd at the NCS D3 Championships. Battling through injuries throughout the season, Moana delivered a strong showing at NCS, earning a 7th-place finish and a spot on the podium.


Junior Jayden capped off a dominant season with 40+ wins and just five losses. A consistent tournament champion throughout the year, he finished 2nd at VVAL and claimed the NCS Division III Championship. Returning to the NCS Championships looking to improve on last year’s 8th-place finish, Jayden powered through the bracket, winning each match by technical fall or pin, to earn an outstanding 3rd-place finish.


The team’s success extended beyond the mat. Justin-Siena was honored with the NCS Scholar Athlete Team Award, recognizing the program as one of the top three academic teams in its division. The award highlights the team’s dedication to maintaining high academic standards while competing at an elite athletic level.
