Dr. Kaplan is Professor of Internal Medicine at the University of Texas Southwestern Medical Center where he has been on the faculty for more than forty years. For the last thirty, his teaching, writing and research have focused primarily upon clinical aspects of hypertension.

He has lectured extensively and contributed over 500 papers to the medical literature. The ninth edition of his textbook, Kaplan's Clinical Hypertension, was published in early 2006. He has been a member of the third, fourth, fifth, and sixth Joint National Committees on Detection, Evaluation and Treatment of High Blood Pressure.

He has been made a Master of the American College of Physicians, given the Lifetime Achievement Award by the American Heart Association's Council for High Blood Pressure Research, and served on the Executive Committee of the American Society of Hypertension from its founding.

Dr. Kaplan sees patients on a one-time-only basis, on referral from another physician. His clinic dates and times vary according to his lecture schedule.
