As a renowned and widely published (more than 200 peer-reviewed publications) hypertension specialist.  Flack's clinical practice focuses almost exclusively on the diagnosis and treatment of hypertension and related-cardiovascular conditions.  He has special expertise in the diagnose and treatment of secondary forms of hypertension, difficult to control (resistant) hypertension and hypertension in African Americans.  Dedicated to improving patient outcomes, he is actively involved in testing new drugs and devices for the treatment of resistant hypertension.   Flack's research also suggest that vitamin D, a safe, cheap and readily available over-the-counter supplement is useful in helping overweight African Americans with hypertension and severe vitamin D deficiency lower their blood pressure and lose weight. 

His treatment philosophy is to gradually lower blood pressure with diet (reduction in dietary sodium, moderation in alcohol intake, appropriate increase in physical activity and weight loss) with careful selection of well-tolerated antihypertensive drugs that are not only effective but safe in the combinations used.
