Our Team


Geneseo Veterinary Service has been located on the corner of IL Hwy 82 and Rt. 6 in Geneseo since 1972.  For over 45 years, clients from Geneseo and the surrounding communities have trusted Geneseo Veterinary Service with keeping their family pets healthy and happy and their livestock productive.  

We are a full service mixed animal practice (which means we treat pets and farm animals).  Our practice is equiped to provide your beloved pet with the latest in medical and surgical care, as well as advanced diagnostic capabilities such as digital radiology, ultrasound, and a full in-house laboratory.  Most large animal work is done on the farm, while pets are seen in our office. Contact us today to learn more about what services we offer for you and your animals!

Our job is not only to treat your animals when they are not feeling well, but more importantly to help you learn how to keep your best friend happy and healthy. We proudly serve the Geneseo, Cambridge, Atkinson, Colona, and Quad City areas.

Dr. Grant Venema grew up in Morrison, IL and later moved to Geneseo where he completed high school.  As a boy, he loved reading the memoirs of veterinarian James Herriot and dreamed of one day having a mixed animal practice of his own where he could make a lifetime of memories helping the people and animals of his community.  He received his bachelor’s degree from the University of Illinois at Champaign-Urbana in 2004, and graduated from the University of Illinois College of Veterinary Medicine in May 2009.  In June 2013 he purchased Geneseo Veterinary Service from retiring veterinarian Dr. Roger Pray. In his free time, Dr. Venema enjoys outdoor activities with his family such as fishing, camping, and hiking.  He lives in Geneseo with his wife Erica, their four children, Penny the Chorkie, and Peter the cat.  

Dr. Dee Ann Kuster joined the practice in June 2020.  She earned her Doctor of Veterinary Medicine from the University of Illinois College of Veterinary Medicine in 1998.  Dr. Kuster is a Geneseo native, growing up on the family farm just north of town.  She and her husband Chris live in Geneseo with their three kids and diverse animal collection.  In her free time she enjoys spending time with family and participating in 4H and equestrian sports with her children.
