Dr. Dennis Luedke
Large Animal Medicine and SurgeryDr. Luedke’s love of animals was cultivated from his desire to follow in his father’s footsteps. Growing up in the Denver area, he was exposed to veterinary medicine at an early age as his father was a veterinarian and virologist and worked in the arthropod-borne disease research lab in Denver. His fondest memories were of taking care of sick and debilitated animals that his father would bring home from the research facility to get intensive care at the family home.
Dr. Luedke graduated from veterinary school at Colorado State University in 1983 and completed a 1-year internship at Littleton Large Animal Clinic upon graduation. Over the next 7 years, Dr. Luedke worked in a 2-man equine-exclusive ambulatory practice in Mesa, Arizona. This practice was primarily involved in equine reproduction, show horses, and racing thoroughbreds and quarter horses. In 1990 he accepted a position as an associate at Glenwood Veterinary Clinic and became an owner of the practice in 1993. Dr. Luedke is currently the senior partner at GVC.

CVTAllison was born and raised in central Minnesota. She spent much of her childhood helping out on her grandmother’s farm and uncountable hours working and volunteering at animal shelters and horse stables. There has also been a myriad of animals her family has had around their own place. Starting at a very young age she knew she was meant to have a career with animals.
Allison got her first degree in Animal Science from the University of Minnesota, but when she found that it wasn’t quite the right fit she went back to school and got her Vet Tech degree from the Mn School of Business.
Throughout the years, Allison had tried working in a few places but it was while being a head wrangler at a ranch in Colorado that she decided that Colorado is where she needed to be, and in April of 2015, she moved back out to CO to work at GVC. Her goal in this career is to take what she can learn and pass it on to pet owners so they can ensure great and happy lives for their pets. Almost all of Allison’s free time goes towards caring for and spending time with her ‘zoo’ of animals which ranges from turtles to horses.
