Dr. Mercado was Professor of Surgery at the Scholl College of Podiatric Medicine where he taught hundreds of students. For over twenty-five years he headed a Podiatric Surgical Residency program training young men and women in the art of podiatric surgery.
Dr. Mercado has written six books and is the best selling author in his field of expertise.
An Atlas of Podiatric Anatomy and An Atlas of Foot Surgery, Vols. I & II are considered classics. The Journal of Canadian Podiatric Medicine wrote "students without this text are depriving themselves of a proper surgical education. Indeed, many podiatrists consider this textbook as their bible for surgery."
He is also the host of the nationally distributed surgical video series entitled, The Art of Surgery. The entire series as well as his major writings have been translated into Spanish for international distribution.
Dr. Mercado has been honored by his peers for his great achievements in the profession by being inducted into the Podiatric Hall of Fame for his lifetime contributions to podiatric surgery. In 2001, he was selected by the Management Journal as one of America's Most Influential Foot and Ankle Surgeons.
