Bringing advanced cancer care closer to home is more than a goal. It is a commitment.

We’re proud to partner with Carilion Clinic to expand access to proton therapy in Southwest Virginia, helping ensure patients can receive highly precise treatment without traveling far from their support systems.

Proton therapy’s ability to target tumors with sub-millimeter accuracy while reducing exposure to healthy tissue is transforming what is possible in cancer care, especially for complex and pediatric cases.

Articles like this highlight the real impact of innovation: better outcomes, fewer side effects, and care delivered where it matters most, close to home.

In March, our team came together for our Week of Hope campaign, supporting the American Cancer Society Hope Lodge communities. 💛

Together, we raised $6,650 and made a meaningful impact through both donations and hands-on involvement:

• 💌 Hope Notes sent to bring encouragement to guests at Boston Hope Lodge
• 🍽️ A BBQ dinner provided for Oklahoma City Hope Lodge
• 🙌 Growing employee interest in volunteering across multiple locations

It’s inspiring to see how our team shows up—with generosity, compassion, and a commitment to giving back.

We’re proud of what we accomplished together and look forward to continuing to support Hope Lodge communities.
