Apex Physics Partners (APP), the largest outsourced medical physics services company in North America, announced its acquisition of RPS Oncology. The addition of RPS Oncology expands APP’s national footprint.
RPS Oncology is a provider of therapy medical physics and dosimetry consulting services in Minnesota and North Dakota. Over the last year, the company has expanded its footprint into Wisconsin and California.
APP is a medical physics business services support organization. Partner physics practices receive an array of support services including client services, information technology and data analytics. APP is backed by Blue Sea Capital, a West Palm Beach-based private equity firm with more than $1.4 billion in assets under management.
This news follows APP’s May 2024 acquisition of Spectrum Medical Physics in Lima, Ohio. Spectrum Medical Physics was incorporated in 2000 to provide radiation oncology physics and dosimetry support to radiation oncology facilities in West Central Ohio.
“Our recent partnerships with RPS and Spectrum continue demonstrating our industry leadership as the preferred partner of choice for best-in-class medical physics businesses seeking a growth-oriented partner,” said Erin Lansky, Principal at Blue Sea Capital. “We are thrilled to welcome Charles and the entire RPS team to the growing APP family and are excited to announce additional medical physics partnerships in the months to come.”
According to data captured in the LevinPro HC database, this acquisition represents the third medical physics transaction of 2024. There were two medical physics deals announced during 2023, and three announced during 2022. This also marks APP’s fourth acquisition since November 2022, and its third announced in 2024. Financial terms of the deal were not disclosed.
