About
Mary Kathryn Eagleton, MD, FAAP, earned her Bachelor of Arts in Psychology, with a minor in Spanish, from The University of Texas at Austin. She went on to complete her medical degree at The University of Texas Health Science Center at San Antonio. Her pediatric residency training took place at the University of Texas Southwestern Pediatric Program at Dell Children's Medical Center in Austin, where she earned board certification in Pediatrics in 2014. She also holds Fellowship status with the American Academy of Pediatrics.
Dr. Eagleton brings nearly a decade and a half of clinical experience to Eagles Nest Pediatrics. She started her career at Children's Medical Group in Austin in 2014, spending three years in private practice before relocating to Tyler. She then worked six years as an outpatient pediatrician at Christus Trinity Mother Frances in Tyler. After a two-year break focused on her family, she launched Eagles Nest Pediatrics with a clear vision: bring personalized, family-centered pediatric care directly into patients' homes. She is passionate about mental health and behavioral support, including ADHD, depression, and anxiety across all pediatric age groups. Outside of medicine, Dr. Eagleton spends time with her husband and three children, stays active outdoors, and - by her own admission - works at parenting her Bernese Mountain Dog.
