Marquis Nuby MD, FAAP
Dr. Nuby was inspired to pursue medicine while obtaining his Bachelor of Science degree in Chemistry at Whitworth University (where he also lettered in varsity basketball), in Spokane, Washington. He obtained his Doctor of Medicine from Weill Medical College of Cornell University in New York City. After graduation, he completed a transitional surgery internship at Howard University Hospital in Washington, DC. He also proudly served as a Captain in the United States Air Force as a general practice physician. During that time, pediatrics became the clear choice of profession when he realized how much he loved working with children. He completed his internship and residency in pediatrics with Baylor College of Medicine at Texas Children’s Hospital in Houston, Texas. He was then a Clinical Scholar in Community Pediatrics at the University of San Francisco- Fresno Residency Program in Fresno, California. During this time, he realized he missed Texas so he moved to Denton. He has been serving local children ever since and is now a Fellow of the American Academy of Pediatrics (FAAP).
