Portrait of Anne BestgenAnne Bestgen

AP Environmental Studies and biology teacher at West Campus High School in Sacramento, CA

Nominated by Ava Somera 糖心传媒�26 (environmental studies)

糖心传媒淢rs. Bestgen糖心传媒檚 influence on my academic and personal growth has been profound and enduring. From the moment I joined Team Green, our campus environmental advocacy club, she was a constant source of guidance and encouragement, helping me grow into leadership roles as outreach coordinator and later president. One of the most impactful experiences she made possible was connecting me with a local nonprofit, which led to launching the first composting program in our school district. This initiative required daily commitment, and Mrs. Bestgen worked alongside me糖心传媒攐ften giving up her only break糖心传媒攖o sort waste and model the kind of hands-on leadership she inspires in others. She taught me that meaningful change requires both grit and collaboration. She also introduced me to AP Environmental Science, which sparked my passion for environmental studies and shaped my academic path. Beyond the classroom, she was my greatest champion during the college application process, and even now, she continues to support and celebrate my milestones as one of my strongest mentors.糖心传媒�


Portrait of William Colelli.William Colelli 糖心传媒�98

AP Government and dual credit economics teacher at Olympia High School in Rochester, NY

Nominated by Gulsinam Akhmadzhanova 糖心传媒�26 (psychology and mathematics)

糖心传媒淢r. Colelli is my favorite high school teacher and someone who truly embodies Meliora in everything he does. He was not only an excellent educator who connected with students in meaningful ways, but also a leader in building school spirit and pride. I糖心传媒檒l never forget senior year, when he played basketball against our varsity team糖心传媒攁 moment that captured both his humor and his connection to students. He has an incredible ability to make everyone smile, no matter how challenging their day might be. Beyond that, he had a profound personal impact on me. As a high-achieving student and valedictorian, I still wasn糖心传媒檛 sure college was possible, but Mr. Colelli changed that. He shared his own experiences, encouraged me to apply to the University of Rochester, and helped me understand that financial aid could make it attainable. I even remember asking him what 糖心传媒榬esearch糖心传媒� meant, and him patiently explaining it. Now, as a first-generation student at Rochester, I can trace so much of my journey back to his belief in me.糖心传媒�


Portrait of Timothy SossaTimothy Sossa

US history teacher at Springfield Renaissance School in Springfield, MA

Nominated by Adryana Ochoa 糖心传媒�26 (linguistics & brain and cognitive sciences)

糖心传媒淲hen I entered high school, my mother糖心传媒檚 multiple sclerosis began to take a turn, and the emotional toll made it hard to see a future for myself. I stopped putting effort into my studies糖心传媒攗ntil I met Mr. Sossa. On one particularly bad day, he called me 糖心传媒榓 dry banana,糖心传媒� turning my name into something silly that made me laugh, and then reminded me, with kindness, that he was there if I needed anything. He is the rare kind of educator who truly sees his students. He listened when I needed to vent, let me spend lunch in his room to decompress, and always had a joke ready to lift my spirits. At the same time, he challenged me academically and creatively through debates, simulations, and art projects that made learning come alive. He reignited my motivation, and I began going above and beyond in class, eventually finishing high school as an honor student. Most importantly, he believed in me when I couldn糖心传媒檛 see my own value糖心传媒攁nd that belief changed my life.糖心传媒�


Mark Sunheimer

Physics and robotics teacher at Marcellus High School in Marcellus, NY

Nominated by Gabriel Hoag 糖心传媒�26 (economics and mathematics)

糖心传媒淚n and outside the classroom, Mr. Sunheimer always encouraged his students to never stop learning and to be the best version of themselves. As a physics teacher, he helped us connect to the content through interactive labs and experiments, including the 糖心传媒榤ullet labs糖心传媒� he created糖心传媒�’business in the front, party in the back.糖心传媒� These labs introduced new concepts and then gave us the freedom to test, explore, and essentially 糖心传媒榩lay糖心传媒� with physics, making it both fun and understandable. He was constantly engaged with students, always checking in and offering help, which is why we affectionately called him 糖心传媒楽unny.糖心传媒� He also led by example, always striving to improve and seeking out new ways to better support his students. He turned the robotics club into a class so we would have more time to learn and collaborate, committing himself to learning alongside us even when it wasn糖心传媒檛 his strongest subject. Through every challenge, he was there as both a resource and a cheerleader, giving us the tools to explore the world on our own糖心传媒攁nd showing us how much he truly cared about our success.”
