About
Dr. Christopher Green is a board-eligible internal medicine physician based in Alton, Illinois, with over 35 years of clinical experience. He grew up in a medical family and carries that second-generation perspective into every patient relationship. His training and career focus on internal medicine and preventive care, with particular attention to chronic condition management and early disease detection.
Dr. Green launched the Concierge Primary Care program at Associated Physicians Group to deliver the kind of thorough, relationship-driven medicine he has always believed patients deserve. He limits enrollment to a small number of members so each patient receives his full attention. Members reach him directly by personal cell or email, any time of day. His annual membership assessment covers advanced screenings and wellness services that standard insurance does not reimburse. Dr. Green also remains in-network for all APG-accepted insurance plans, so routine clinical services continue to flow through insurance as usual.
