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. He is on the board of directors for the AAEP and is a past member of the AAEP Ethics Committee. Dr. Baus is a past president of the Northeast Association of Equine Practitioners.
