PSPA Executive Board

Lisa Billington


Mom to Gabrielle `20, Bradley, Morgan, and Lance.

Lisa joined the Pingry community in the Fall of 2016 and immediately began volunteering with the Pingry School Parent Association. Wanting to learn more about the school her daughter was attending, Lisa chose to be “all-in” as she supported and attended various events throughout the school year. She was instantly inspired by the diversity represented in the Pingry community and enjoyed getting to know many families throughout the school’s campuses.

Lisa graduated from Winthrop University where she earned a Bachelor’s degree in Broadcast Journalism. In the early years of her marriage to Courtney, an army lieutenant at the time, she continued her education and earned a M.A.Ed degree. While they moved often, Lisa taught in many high schools and colleges and also enjoyed working as a corporate training specialist.  She has owned and managed her own businesses in professional development while also staying at home and raising their four children. 

Lisa’s constant commitment to volunteering in churches and organizations has cultivated a love for mentoring and coaching youth and women, emphasizing cultural awareness and leadership development. This is where she has enjoyed the most personal growth and life-long learning!

“I love volunteering at Pingry because every day is a new experience while getting to know those who make up this awesome community.  We all have so much to share with and gain from each other while we support our children in their educational journeys.

My favorite PSPA events are MLK Day of Service, coming together to support many individuals and organizations in one day and Friday Night Lights- families enjoying a beautiful fall night of football, fun and Big Blue Pride!”

Lisa enjoys tennis and pursuing health and wellness. She loves vacations with her family and friends, especially at the beach!

Anne Wargo

Second Vice President

Mom to Caroline '20

The Wargo family joined the Pingry community in 2012, for Caroline's Grade 5 year.  

Anne graduated from Skidmore College with a double major in English and French. Anne's work as a strategy consultant changed over time and she now works as a consultant and an executive coach, focused on supporting women. Her work as a strategy consultant and her coaching work have shaped her volunteer work as well.

“I strongly believe in that phrase from the bible: "to whom much is given much is expected." The work that we do to support Pingry is critical to the school's success and therefore to our children's success. I've felt great about the role the PSPA plays at Pingry and the unique environment that we help nurture. The best reward for my work with the PSPA is that I've also made some lifelong friends from my time volunteering.”

Anne's favorite Pingry event is Friday Night Lights. "Its a great event that allows the whole community, parents and students to connect and enjoy one of Pingry's marquis events."  

In her free time, Anne advocates for the Wargo's 20 year old son who has Autism. She is an avid gardener, a so-so golfer and loves her yoga practice.

Larry Li

Grades K-1 Representative

Dad to Kaylee `31

I joined the Pingry family in 2018 when our daughter Kaylee entered Kindergarten.  

As full-time working parents, my wife Yuki and I work hard to balance family and work. We both do our best to be involved and participate with school events and after-school activities as much as possible. Outside of school our hobbies are skiing, soccer, and basketball.  My wife and I believe that children have a positive impact in their academic and social performance when parents are involved and participate in their child’s education and interest.

I am honored to be a PSPA member and to serve the next school year as a K - 1 Representative.  I will have the opportunity to engage and collaborate with teachers and staff. I hope to be the “window” for other teachers and parents to bring their perspectives to the table. My wife and I are looking forward to being part of a community that communicates and contributes.
