What Proton International does
Proton International LLC is a private, founder-led healthcare development firm that plans, finances, builds, and operates one- and two-room proton therapy centers in partnership with hospitals and physician groups. Founded in 2013 by Chris Chandler and headquartered in Alpharetta, Georgia (with a Kentucky domicile), the company is a subsidiary of Healthcare Technologies International (HTI), which has developed more than 250 cancer centers across four continents since 1972. Its core offer is a smaller, lower-capital alternative to traditional multi-room proton facilities — typically $40M–$75M one- and two-room builds that can be embedded within existing hospital infrastructure rather than constructed as standalone facilities, at roughly one-tenth the cost of conventional four-room centers.
The underlying technology is proton beam radiation therapy: a cyclotron accelerates protons and a beam transport system directs them via a gantry to deposit energy at the Bragg peak in the tumor, sparing surrounding healthy tissue. The company's deployed systems include Pencil Beam Scanning (PBS) for intensity-modulated proton therapy (IMPT), and it works with leading vendors including Varian (via the ProBeam platform at UCLH London) and Hitachi (via the UW Health collaboration). One-room facilities have stated capacity for approximately 40 patients per day, with mature centers ramping to roughly 600 patients per year.
The business model combines (i) developer/owner economics from facility equity stakes, (ii) project management and consulting fees for turn-key delivery spanning business planning, financing, technology selection, design/construction, training, and operations support, (iii) ongoing operational management contracts at partner sites, and (iv) an international patient referral program that routes patients from regions without domestic proton centers to PI facilities. Eleven centers have been developed or are under development across the US (Arkansas, Alabama, Florida, Michigan, Connecticut, Wisconsin, Texas), the UK (UCLH London), the Netherlands (UMCG Groningen), Germany (University Hospital Halle, in design), and China (Hangzhou office and a JV with Glorying Health). Marquee partners include UAB, UAMS, Baptist Health, Arkansas Children's, Hartford HealthCare, Yale New Haven Health, UCLH, UMCG, Delray Medical Center, UT Health San Antonio, and UW Health, with Loop Capital providing exclusive non-recourse project financing.

Products and services
- One- and Two-Room Proton Treatment Centers Turn-key proton therapy facilities that can be built into existing hospital infrastructure rather than requiring separate standalone buildings. A one-room center can treat approximately 40 patients per day and can be constructed at roughly one-tenth the cost of traditional four-room centers.
- Global Consulting Services Comprehensive consulting services from conception to completion of proton therapy centers, covering business planning, organizational structure, clinical program evaluation, financing, technology selection, building design and construction, training, and operations. Targeted at hospitals and physician groups seeking to develop proton therapy capabilities.
- International Referral Program Program that assists cancer patients from regions without operational proton centers to receive treatment at Proton International's partner facilities, providing travel assistance, airport pickup, hotel reservations, interpreter services, and transportation coordination.
- Proton Therapy Treatment Proton beam radiation therapy delivered at Proton International-owned and operated facilities, using proton beams instead of X-ray photons to target cancer cells with greater precision. The Bragg peak allows most energy to be deposited directly in the tumor, minimizing damage to surrounding healthy tissue and reducing side effects. Treats multiple cancer types including brain, breast, head and neck, lung, pediatric, prostate, and others.
