Our Doctors

Our clinic is staffed by three doctors: Dr. Hank Oliver, Dr. Andrianna Krippaehne, and Dr. Jenna Barker. Dr. Krippaehne cares exclusively for our small animal patients while Drs. Oliver and Barker provide care for both large and small animals.

Dr. Hank Oliver, our lead veterinarian, graduated from the Washington State University College of Veterinary Medicine cum laude in 1980. He has practiced in Pasco continually since 1982. Dr. Oliver has given many talks for local clubs about issues relating to animal health and was even a guest speaker at the Jackson Hole Veterinary Rendezvous in Wyoming. He and his wife are very involved in equestrian activities and sports; Dr. Oliver previously served as president of the Tri-Cities Polo Club.
