Marc D. Krock, M.D.

Dr. Krock is certified by the American Board of Internal Medicine in Cardiology and Interventional Cardiology and has been practicing cardiology in North Texas since 2005, starting in Plano. He was the Director of Peripheral Vascular Disease as well as the Chief of Cardiology at The Medical Center of Plano for several years, and was voted Cardiologist of the Year by the hospital staff in 2012.

Following his years of practice as a member of a large cardiology group in Plano, Dr. Krock began 2015 with a goal of establishing his own practice where the emphasis would be on building strong patient relationships based on mutual respect and trust. That goal became a reality in the Spring of 2015 with the opening of The Heart Smart Group office in The Medical Center of McKinney.

Dr. Krock, who is fluent in Spanish, is also interested in bikram yoga, scuba diving, and can be heard periodically on “Rock with Doc Krock,” on 92.5 Lone Star Radio.
