Mark Spare

DVM

Mark Spare returned to his Clark County roots in August 2022 to join the AVC team after earning his PhD and DVM degrees at K-State’s School of Veterinary Medicine in 2019. Prior to entering vet school, Mark took advantage of several opportunities to gain hands-on experience, including a stint in Russia during the development of the largest beef operation in Russia. His collective body of experience in America and abroad renewed the value of his upbringing, and solidified his decision to make a career out of serving others in agriculture through the practice of veterinary medicine.

As an AVC veterinarian, Mark provides care to both small and large animals. He focuses on herd health, diagnosis and nutritional consultation. Mark also assists with AVC’s semen sales and extensive breeding services, including synchronization, artificial insemination, ultrasound pregnancy determination and palpation with the goal of increasing producer profitability. Mark and his wife, Kayla, are parents to three daughters: Elizabeth, Lydia and Moriah.
