Large Animal Veterinarian and Practice Owner
Dr. Mark Debner is a large animal veterinarian and owner of Anderson Veterinary Service. He
graduated from the University of Minnesota College of Veterinary Medicine in 1992 and has
dedicated more than three decades to serving producers and their animals. Before joining AVS,
Dr. Mark gained experience across a variety of roles in the agriculture and veterinary fields—he
worked in Iowa dairy farming, spent time at Winona Veterinary Clinic, Wabasha Veterinary
Clinic, and Zumbrota Veterinary Clinic, and served as a consultant with Nelson Nutrition
Consulting. In 2002, he joined Anderson Veterinary Service, where he has spent over 20 years
building strong client relationships and providing practical, hands-on care for livestock.
An active member of the Minnesota Veterinary Medical Association (MVMA), the American
Veterinary Medical Association (AVMA), and the American Association of Bovine Practitioners
(AABP), Dr. Mark is committed to continued learning and professional involvement within the
industry. While he enjoys working with a wide variety of species, his heart remains with dairy
cattle, a passion that began when he operated his own dairy before becoming a veterinarian.
For Dr. Mark, the most rewarding part of veterinary medicine is the relationships he has formed
with clients over the years and the satisfaction of seeing animals recover and thrive. He finds
great joy in hearing from producers that an animal is “doing better than ever” after treatment,
a reminder of the impact his work can have on both animals and the people who care for them.
Outside of veterinary medicine, Dr. Mark leads a full and family-centered life. He and his wife,
Brenda, recently celebrated 40 years of marriage. Together, they are proud parents of four
children, each making their mark across the country: Ryan, a laboratory quality technician in
Denver, CO; Rachel, who works in California developing accessibility software for people with
disabilities; Nathan, a veterinarian in Idaho; and Matthew, who is completing dental school at
the University of Iowa. At home, the Debner’s keep a variety of animals on their acreage, which
has broadened Dr. Mark’s appreciation for species beyond cattle.
When he isn’t working, Dr. Mark enjoys spending time outdoors—whether fishing, kayaking,
checking cows out on pasture, sitting in a deer stand, or being involved in church activities. For
him, veterinary medicine is not only a career but also a calling, one that has allowed him to
combine his love of animals, agriculture, and people in a meaningful way.
Whether in a barn, on the water with a fishing pole, or at church on Sunday, Dr. Mark finds joy
in the simple things and in serving both people and animals.
