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 atthe 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.
