Who We Are
Dr. DJ
Owner & Mixed Animal Veterinarian
Dr. Weimer grew up on a diversified farm in central Indiana. Growing up on the farm allowed him to develop a passion for agriculture at a young age. He attended Purdue University and received his Bachelor's Degree in Animal Sciences in 2007 and his Doctorate of Veterinary Medicine in 2011. It's at Purdue College of Veterinary Medicine where he met his wife and co-owner of Heartland Vet Care. In 2012, he started Livestock Veterinary Services with the goal to help livestock producers optimize their production practices to ultimately become more efficient and profitable. In 2018, he collaborated with his wife Dr. Sarah and together they started Heartland Vet Care. ​ In addition to veterinary work, Dr. Weimer also runs a commercial cow-calf operation, seed stock operation, and a beef feedlot facility. He currently lives in Knightstown, Indiana with their two kitties Daniel and Sandra and their daughters Charlotte and Gwendolynn.
