Serving Lake Forest Adults
Primary Care Without the Usual Rush
Traditional primary care can make it difficult to schedule a timely visit or discuss several concerns in one appointment. IASIS uses a smaller membership panel so Dr. Karanastasis can provide longer visits, direct communication, and clearer follow-up for adults from Lake Forest and surrounding North Shore communities.
Care is provided from the IASIS office in Orland Park, with telehealth available when clinically appropriate. Patients can also learn about our comprehensive adult primary care services.
