On April 22, Ziegler announced that it advised Cancer Center Oncology Medical Group (CCOMG) throughout its acquisition by Cancer Care Specialists (CCS).
CCOMG is an oncology practice based in La Mesa, California. In addition to general oncology services, CCOMG provides chemotherapy, immunotherapy, hormone therapy, clinical trial, hematology and genetic testing services. According to its website, there are four physicians on staff.
CCS is a leading provider of quality evidence-based oncology and hematology care and treatment to patients across Nevada and California. It is backed by Levitate Ridge Capital, a private equity firm focused on investing in lower middle-market healthcare and business services companies.
Through this deal, CCS and Levitate Ridge Capital will support continued investment in physician-led oncology practices, clinical capabilities, technology infrastructure and geographic expansion while preserving the independent practice model that is critical to community-based cancer care. Terms were not disclosed.
This marks the third deal that Ziegler has advised on since the start of the year.
According to data in the LevinPro HC database, this transaction represents the 166th Physician Medical Group (PMG) acquisition of 2026, and the third in the oncology specialty. Throughout 2025, 521 PMG deals were reported, and nine in the oncology specialty.
