Dr. Joseph J. Koch started his veterinary career at Lincoln Land Animal Clinic in 1989 when it was strictly a large animal practice. Dr. Joe expanded the practice to include small animal medicine and surgery into the clinic you all know and love today. Dr. Joe graduated from the University of Illinois Veterinary Medicine program in 1988 and continues to practice both large and small animal medicine. 

Dr. Joe can often be seen in his Carhartt overalls on farm calls or in his Cookie Monster scrubs at the office. Veterinary medicine continues to intrigue Dr. Joe, and he finds true joy in helping animals and their owners.

When he’s not working, Dr. Joe can be found playing guitar, volunteering at his church, cheering for the St. Louis Cardinals, or going for walks with his wife, Dr. Colleen Koch, and their Icelandic sheepdog, Kennari.


Dr. Colleen S. Koch is also a graduate of the University of Illinois College of Veterinary Medicine and graduated in 1990. She joined the Lincoln Land Animal Clinic team in 2001 practicing both small and large animal (primarily equine) medicine. She has always enjoyed working with animals labeled as “difficult”, even before she went to vet school. In 2013, Dr. Colleen followed her passion and completed a veterinary residency program in animal behavior through the American College of Veterinary Behaviorists.

Dr. Colleen is now one of 86 board certified veterinary behaviorists in the world, and one of only two veterinary behaviorists seeing clinical cases in Illinois, and the only one seeing clinical cases in Missouri! Dr. Colleen sees behavior patients both at Lincoln Land Animal Clinic and at the University of Missouri Veterinary Health Center in Wentzville, Missouri.

Dr. Colleen continues to dedicate herself to the animal behavior field. In addition to helping people with their pets, she mentors a veterinary behavior resident and often serves as a preceptor for Mizzou veterinary students. She is a nationally recognized speaker and continues to promote the human-animal bond as she guides pet owners through some of the more challenging aspects of pet ownership.

She is a Jacksonville native and previously worked at LLAC in multiple positions while she earned her bachelor’s degree in Biology and Chemistry from Illinois College.

Dr. Artis has a special interest in small animals and pocket pets. She enjoys performing surgeries and interacting with our staff and clients. She also enjoys mentoring undergraduate interns.

Dr. Artis adopted her cat, Morgan, during her junior year of veterinary school. Morgan was her junior year surgery patient and it was love at first sight. 

When she is not working, Dr. Artis can be found spending quality time with her family and her husband, Shawn, as well as traveling.
