What an incredible weekend—more than 150 alumni and faculty from Allendale, Columbia, and Allendale Columbia Schools gathered for our All-Alumni Cocktail Party and Reunion celebration!
A highlight of the weekend was honoring Nancy Hodge Lee ’46 with the 2026 Distinguished Alumni Award. Her lifelong connection to AC and the impact she has made throughout the years are a wonderful reflection of the values and traditions that continue to unite our community.
Thank you to everyone who returned to campus to reconnect, reminisce, and celebrate what makes AC so special. You can check out photos from the celebration here.
Thanks to those who joined us at the AC Alumni Holiday Celebration!
The AC Alumni Association proudly hosted the annual Alumni Holiday Party at Tin Cup Social, co-owned by Mike Mrzywka ’01, on December 30, 2025.
A generous thank you to our sponsor, David C. Burdick '85.
AC provides so much more than an education---it offers a lifetime of personal and professional connections. Along with current students, parents, faculty, staff, and friends, alumni are a key part of the AC network.
AC relies on a strong network of alumni who give of their time to support the extraordinary AC experience. Volunteers help organize class reunions, participate in phonathons, serve as campus speakers, and much more.
Gifts made each year to Allendale Columbia School provide students with critical resources and access to a transformative academic experience.
The generosity of the AC community can be seen our students' ability to succeed in college and in an ever-changing world. These students go on to serve and lead the communities in which they live.
The AC Alumni Association is a volunteer body with class representation from a variety of years. The mission of the Board is to partner with the Office of Advancement and Alumni Engagement to build and perpetuate an alumni community of support for the school.
At Allendale Columbia, we prepare students for the world they will inherit. In our trusting and responsive environment, students 18 months through grade 12 grow in confidence and develop scholastic independence.
