A big congratulations to Mevion Field Service Engineer Johnathan Miles (Miles) on being named the recipient of the OHMG (Orlando Health Medical Group) BEE Award! 🐝

The BEE Award recognizes team members who go above and beyond to create a positive patient experience - and Miles exemplifies that every day through both his technical expertise and his genuine connection with patients.

At Mevion, our Field Service Engineers do far more than support world-class proton therapy technology. They become part of the patient experience itself - building trust, answering questions, educating caregivers, and helping ease anxiety during some of life’s most difficult moments.

We sat down with Miles to learn more about his background, what brought him to Mevion, and what motivates him each day.

Congratulations again, Miles, on this well-deserved recognition. Thank you for representing the very best of Mevion and for showing that patient care extends far beyond the technology itself. 💙

A major milestone for cancer care in Massachusetts.

Dana-Farber Cancer Institute will bring proton therapy to its Longwood Medical Area campus using the MEVION S250-FIT™ Proton Therapy System.

This project represents an important step forward in expanding access to advanced proton therapy for pediatric and adult patients across New England, directly within one of the world's leading cancer care environments.

At Mevion, we believe proton therapy should be more accessible to the patients who need it most. We are honored to support Dana-Farber's vision to bring highly precise, patient-centered cancer care closer to home, and grateful to our partners at Leo Cancer Care, whose upright positioning technology makes this kind of integration possible.

Congratulations to the Dana-Farber team and everyone who helped make this milestone possible. https://hubs.la/Q04gw6-B0
