Affiliated Oncologists

What Affiliated Oncologists does

Affiliated Oncologists is a private, community-based oncology practice operating seven clinical locations across Chicago's South suburbs (Chicago Ridge, Hazel Crest, Orland Park, Oak Lawn, Downers Grove, and Mokena). Established over 50 years ago, the practice delivers multidisciplinary cancer care spanning medical oncology, hematology, radiation oncology, and gynecologic oncology, supported by treatment modalities that include chemotherapy, biological therapy, targeted therapy, immunotherapy, hormonal therapy, radiation therapy, bone marrow transplant evaluation, and radiopharmaceuticals. Adjacent patient services include on-site laboratory, diagnostic imaging, medication dispensing, financial counseling, genetic risk education, second opinions, and telemedicine. The practice holds QOPI (ASCO), ACR, and ACHC accreditations and participates in the CMS Oncology Care Model.

The business model is fee-for-service outpatient oncology, billed through Medicare, Medicaid, and commercial payers, supplemented by episode-based performance payments under OCM and ancillary diagnostic and support service revenue. Patient acquisition occurs through physician referrals, self-referrals, online appointment requests, and hospital partnership arrangements (including a radiation oncology presence at Advocate Christ Medical Center). As a member of The US Oncology Network, Affiliated Oncologists accesses shared clinical pathways, drug procurement, and management services supported by McKesson, while clinical trial access is enabled through a partnership with the Sarah Cannon Research Institute. A 2026 partnership with Protocol Behavioral Health extends the offering into integrated oncology-specific behavioral health under the Collaborative Care Model. No public revenue, ARR, funding, or headcount-growth disclosures are available; employee count is stated at 51-100.
