Rivas previously served as CEO of R1 RCM from January 2023 until the company was taken private in November 2024. He joined R1 in June 2022 following its acquisition of revenue recovery provider and consultant Cloudmed, where he was CEO.
In the release, Rivas said he was excited to join Xsolis at an important stage in its evolution, citing the team's work reducing friction between hospitals and health plans and its relationships with health systems.
