Rachel Millar

My name is Rachel Millar and animals, both large and small, have been a constant fixture in my life since birth. Both my father, and grandmother, are veterinarians;specializing in equine. My family has owned and operated a large registered Brangus cattle and registered American Quarter Horse operation in central Oklahoma for the better part of thirty years. Although I have primary been around large animals most of my life, I do love working with the small and furry. I have also been known to bring a few of the small and furry home from time to time. I am blessed to have a beautiful three-year-old daughter, Kynlie, who certainly shares the family affinity for all of God’s creatures. Veterinary medicine is both a fascinating and rewarding field and I am so thankful to be a part of it every single day.
