Why Concierge Medicine
Choosing to Practice Medicine With Fewer Barriers
After many years of practicing traditional insurance-based medicine, Dr. Karanastasis felt the system was moving away from the kind of care patients truly need.
Patients often wait weeks for appointments, spend time on hold, sit in waiting rooms, and then receive only a short visit. For someone managing multiple medical conditions, 10 to 15 minutes is often not enough time to listen, examine, explain, and plan.
That is why he built IASIS Boutique Health around concierge medicine. A smaller patient panel creates more time for each patient, better communication, and a stronger doctor-patient relationship.

“My dream is to practice medicine the way I was trained to do so without the barriers and restrictions of health insurances.”Georgios Karanastasis, MD
