  • Rachel Millar
    Veterinary Assistant

    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.

Read What Our Clients Say

  • "The staff is so considerate and gentle with my older dogs. They suggest care and treatment options with no pressure and explain cost and objectives."
    Janet G.
  • "Fantastic amount of knowledge and love for animals! One of the few places I trust with my animals."
    Christopher G.
  • "The veterinarians and staff are so friendly and compassionate. I recently lost my beloved Shi-zu, which I've had for 16 years. I just couldn't take him in to the examing room to send him to a better place and so Dr. Liz came out to our house to send him on his way....this was the hardest thing I've ever had to do in my life. If it wasn't for Dr. Liz and her compassion I really don't think I could have gotten through this....like all pet lovers say, "It's like loosing a child....I also had him cremated and when I picked up his ashes the staff cried along with me...so I just want to say "THANK YOU" sooo much for caring...The people that work here are truly the best...love you all...."
