Code Loudoun's Code-a-thon is a free event thanks to our amazing sponsors. Through services, food, t-shirts, and supplies our sponsors made the 2018 Code-a-thon, the first at PFHS, an incredible success. The only disappointment was when we had to turn away students because we didn't have funds to serve more than 100 students.



Now it's 2019 and the planning is underway! The news of our success has spread and interest is strong. This year, we're aiming higher and opening the registration to 200 students. We know we can reach our goal because of you.


This is your opportunity to help develop the next generation of technology industry workers, in your own backyard. With your tax free donation, we can expose and encourage more kids in Loudoun County to learn more and spike their interest in computer science and programming!

Our student helpers who helped daylong Anthony Panagides, Zohayr Naveed! Thank you Dana Altarace. Thanks to Isha Liu for designing the T-shirts and logo! Thanks to teachers and workshop conductors - Matt Nowinski, Yaro Mayewsky, Nagesh Chintada, Hemanth Setty, Fred Morrison, and Dave Gillis! Our school building staff led by Mr. Shah.
