The Team Behind 43 Oncology

Radiation oncology is a small world. The engineers who keep linear accelerators running, the physicists who commission them, the administrators who budget for them — most of us have crossed paths at some point, in a vault at 2 a.m. or on the phone trying to source a part before Monday’s patient schedule.

43 Oncology was built by people from that world. Not investors who saw a market opportunity, but service engineers and industry veterans who spent years inside cancer centers and got tired of watching facilities pay OEM prices for support with no sense of urgency behind it. We started this company because we believed independent service could be done at OEM quality, with better response times and honest pricing.
