🚨News: The Arc of Loudoun Inks a Lease to Relocate Aurora School to The National Conference Center; Files Suit to Protect Students Following Unlawful Lockout

August 15, 2025 — Today, The Arc of Loudoun shares two important updates:

First, with deep gratitude and great relief, we announce that the Aurora School will relocate to The National Conference Center (NCC) in Leesburg.

While this is likely not our long-term home, it allows our students to learn together once again under one roof, alongside the rest of our programs, in a safe and supportive setting.

We are indebted to NCC’s owners and staff for stepping forward to expand our partnership in this time of need!

Second, we filed a lawsuit in Loudoun County Circuit Court today against the Margaret Paxton Memorial for Convalescent Children and its trustees.

The Complaint details, among other things:
- how the trust has violated the requirements of the real property tax exemption;
- that it barred The Arc from the campus without serving a Notice to Quit or other notice;
- and that it is unlawfully preventing students with disabilities from attending class,..all of which may cause irreparable harm to The Arc of Loudoun and its students.

The Complaint further asks the Court to issue a temporary restraining order and preliminary and ongoing injunctions forbidding all of the defendants from barring The Arc’s access to the Paxton Campus.

Aurora School will remain closed to students through August 20th while the restraining order and injunctions are processed, staff can get into our buildings, techs can restore our IT network, our facilities’ team can methodically check every Arc space on campus for damage or missing assets, and to allow time for us to prepare the welcome back to campus that our students deserve.

We’ll also continue preparing for our move to our new space at NCC with the goal of relocating as quickly as we can.

We’re working closely with our partners at the Virginia Department of Education to ensure a smooth transition for all of our students, staff, and school systems.

To our community, please know this: The Arc of Loudoun is strong, our mission is unwavering, and we will not be deterred from doing what is right for the children and families we serve every time, all the time.

We are profoundly grateful to our partners, neighbors, and friends who have stood with us through this summer of uncertainty.

While there is a strong, sure path forward, we still need the community to rally around our students and families.

We invite you to:

1. Share this message to spread awareness. Contact your elected officials and ask them to stand with The Arc of Loudoun.

2. Collect packing supplies: Please begin collecting new or gently used moving boxes, packing tape, bubble wrap, and markers. Please do not bring these items to Paxton Campus or to The National Conference Center just yet. We will share updates soon about when and where you can deliver them.

3. Volunteer: If you are willing to lend your time and energy once the dates for the move are finalized, please email [email protected] so we can reach out when help is needed.

4. Donate: Community support has always sustained The Arc of Loudoun. Your financial generosity today will help safeguard our programs and ensure a future for the families we serve. Please donate: https://arcofloudoun-bloom.kindful.com/?campaign=1286583

Your support fuels our mission and reinforces these truths: that our students and staff belong in their classrooms, that our clients and families deserve the very best services and support, and that The Arc of Loudoun will do whatever it takes to bring about a just, equitable world for people with disabilities.

With gratitude,

Lisa Max
CEO, The Arc of Loudoun

The Arc of Loudoun’s Ability Fitness Center Relocating to The National Conference Center

We are delighted to share that The Arc of Loudoun’s Ability Fitness Center is relocating to The National Conference Center. The move will increase AFC’s footprint nearly fivefold, from 1,200 square feet to almost 6,000 square feet, eliminating the longstanding waitlist and making room to serve more clients with life-changing services. The expanded location will also provide the opportunity to add a much-needed pediatric program, which will be the first of its kind in Loudoun County. ā€œWe are proud to support The Arc of Loudoun’s mission and welcome the Ability Fitness Center to our campus,ā€ said John Walsh, Vice President & General Manager of The National Conference Center. ā€œThis partnership reflects our commitment to serving the broader community in meaningful ways.ā€
