Katherine “Katie” Collier joined North Dallas ENT as a Family Nurse Practitioner, bringing more than fifteen years of clinical experience to the practice. She earned her undergraduate degree from The University of Texas at Austin and later completed her Master of Science in Nursing at The University of Texas at Arlington. Katie is board-certified as a Family Nurse Practitioner.
Katie began her career in the Cardiac Intensive Care Unit at Children’s Health, where she served as a Registered Nurse for nearly ten years. She later transitioned into outpatient pediatric cardiology as an Advanced Practice Provider before pursuing a specialty focus in sleep medicine. Over the past five years, she has developed extensive experience in the diagnosis and management of sleep disorders, helping patients improve their health and quality of life.
As a member of the American Academy of Sleep Medicine, Katie is committed to using proven clinical protocols and individualized treatment plans to achieve the best possible outcomes for her patients. Her dedication to the field was inspired by her father’s distinguished 40-year career as a respiratory therapist.
Katie is originally from the Carrollton area and now lives in Frisco with her husband and three daughters. Outside of work, she enjoys traveling, attending live music events, and spending quality time with her family.
