Paul Lyde, MD
Paul Lyde, MD
Medical Doctor
Dr. Lyde is a Board Certified Internal Medicine physician, who has practiced in the Irving/Coppell, Texas area since 1991. The treatment of patients with diabetes and prevention of complications has long been an interest for Dr. Lyde since it was a condition seen so often in his primary care practice. He notes tremendous advances in understanding the biology of diabetes have occurred since he graduated from UT Southwestern Medical School in 1985. These understandings have enabled healthcare providers like Dr. Lyde to guide patients to goals proven to prevent complications and improve quality of life. Working with a team which includes diabetes educators makes achieving these goals a reality for patients. Dr. Lyde enjoys the meaning in his life that comes from guiding a person through difficult terrain to safe ground, especially when they just didn’t think it could be done. Dr. Lyde has lived in Coppell with his wife and two children since 1994. He is a volunteer and medial director for the Metrocrest Family Health Clinic, a charity clinic providing access to healthcare for people in the Farmers Branch area who would not otherwise be able to receive care. Dr. Lyde is a parishioner at St. Ann Catholic Parrish and is active in the Coppell High School Band Booster program where his children are musicians. And, of course, he enjoys a game of golf now and then.
