Patient Reviews
Mar 18, 2022
I have severe hypertension, and Dr. Flack is an expert in this field. He has been able to find a combination of drugs that have lowered my blood pressure noticeably, and reduced my risk of a coronary event. He is also conservative in his approach to surgical intervention and is very accessible to his patients. His demeanor is friendly, yet professional, and he refers only to the top specialists in their fields, in Springfield, Illinois. I am very pleased to have Dr. Flack as my primary care physician.
