“Dr. Shah has brought great value to the company,” said AON Chief Executive Officer Todd Schonherz. “He is passionate about community oncology and breaking down the barriers to cancer care to ensure equitable access to healthcare in both urban and rural areas. As the company expands its reach and impact, it is important to bring on individuals aligned with our mission, just as Dr. Shah is, to continue providing value to those in our network.”

Dr. Divers joined the AON Board of Managers in January 2022 and is a medical oncologist at AON’s partner practice Genesis Cancer and Blood Institute in Hot Springs, Arkansas.
