Mark R. Baus, DVM

In addition to memberships in the American Veterinary Medical Association and American Association of Equine Practitioners, Dr. Baus is on the veterinary committee for the United States Equestrian Federation and the Horse and Rider Advocates Committee for the United States Hunter Jumper Association.
