✨ At Mevion Medical Systems, our connections at ASTRO begin well before the meeting itself. Yesterday, we had the privilege of gathering for a Clinical Advisory Board meeting at Stanford Medicine Cancer Center, home to the world’s first MEVION S250-FIT™ proton therapy system.

The theme of the day was clear: proton therapy is on the rise, and Mevion is leading the way.

Our CEO, Dr. Tina Yu, reflected on a remarkable year that included:
• FDA clearance of the Mevion S250-FIT System
• New centers underway at Stanford, Nebraska Medicine, Loma Linda University, Baycare, and Atlantic Health

The enthusiasm from our board was evident. The meeting concluded with a behind-the-scenes tour of the fully installed S250-FIT™, where members experienced firsthand the power of the world’s smallest cyclotron.

We left energized by their excitement and inspired by the future ahead. This is only the beginning of a new era in patient care—and Mevion is proud to be leading it. 🚀
