Dr. Jennifer Hart has spent most of her years growing up in the Bartlett area. As a young girl she would always bring home and raise a variety of animals to take care of. That's when her love for all types of animals grew into her growing practice it is today. She followed her interest and love for animals and graduated from the University of Illinois, College of Veterinary Medicine in 1989. She completed her board certification by the ABVP (American Board of Veterinary Practitioners) in 1998, specializing in canine and feline medicine. Dr. Hart completed her dream of opening Heartland Animal Hospital in 1993. She is a proud mother of her son that is now in High school and loves to play baseball. She loves attending all of his games! She also has furry children that she takes care of. Georgie, Rosie, and Willy are cats. Hank her Rottweiler mix is 9 years old, and Dexter a Dachshund mix is her newest addition. Both dogs were adopted from local rescues. Sometimes you can see Dexter hanging around the office. He loves to come to work with his Mom. Dexter does play the role of the boss so we let him think he is! She takes great pride in keeping her staff well trained and the hospital up to date with new technology and services.
