Meet Our Doctors

Palos Animal Hospital is staffed with a team of professional, compassionate doctors to care for your pet. If you have any questions about our doctors, don’t hesitate to ask.

Dr. Thomas R. Kleven

Dr. Kleven has been a veterinarian at Palos Animal Hospital since June 1978, the only position he’s held since earning his Doctorate of Veterinary Medicine from the University of Illinois. He has a special interest in weight management cases in dogs and cats. His decision to pursue veterinary medicine stemmed from his enjoyment as a kennel assistant at Striegel Animal Hospital in Carbondale, IL, in 1972. Throughout his career, he continues to enjoy the various aspects of a veterinary practice, including forming relationships with his clients, their families, and their pets while nurturing the human-animal bond. He also enjoys working with such a large staff and being involved in a wide variety of pet care cases.

To stay current on the latest changes in veterinary medicine, he has completed continued education courses on a variety of medical topics. He is also a member of several veterinary organizations, including the American Veterinary Medical Association, American Animal Hospital Association, Chicago Veterinary Medical Association, and Illinois State Veterinary Medical Association.

Dr. Kleven and his wife, Karen, have two sons named Phil and Brett. He also has a golden retriever named Tally. When he’s not at work, he loves to read, work outside, watch sports and listen to classical music.

Dr. Jeff Sankey

Dr. Sankey is a graduate of Ontario Veterinary College and has been working at Palos Animal Hospital since August 2008. He has a special interest in ultrasound and surgery. Before veterinary school, he worked at the hospital for many years as an assistant. Dr. Sankey has completed several continuing education courses in veterinary medicine, including a small animal ultrasound course at the Ontario Veterinary College, presented by Life Learn. Throughout his career, he has enjoyed working with several different animal species, including large and exotic animals. He loves being able to help his patients and clients while creating an enjoyable work environment for his colleagues.

Dr. Sankey shares his home with his beautiful wife, Allison, and their pets: a cat named Knuckles, a Yorkshire terrier named Tino, a shih tzu named Charlotte, a cocker spaniel named Colby, and fish in a coral reef tank. When he’s not at work, he likes to do wood working, handyman projects, and work on his classic 1967 Dodge Coronet. He also enjoys playing drums—which he’s done since 5th grade—and spending time with his wife and four-legged kids.

Dr. Joel Mills

Dr. Mills has been with the Palos Animal Hospital team since June 1997 and has a special interest in ophthalmology cases. He earned his Doctorate of Veterinary Medicine from the University of Illinois. After working at a veterinary practice in high school, he decided in college that he wanted to become a veterinarian, due to his interest in medicine. As one of the practice’s associate veterinarians, he enjoys working with his fellow employees and interacting with his clients and patients. He also loves that there is always something new to see or do while on the job.

To stay current on the latest trends in veterinary medicine, Dr. Mills is affiliated with the Chicago Veterinary Medical Association, American Veterinary Medical Association, and the Illinois State Veterinary Medical Association (ISVMA). He has also completed continuing education courses at ISVMA as well as the Western Veterinary and North American Veterinary conferences.

As a pet lover, he shares his home with two four-legged friends of his own, a pit bull named Payton and a cat named Retro. In his spare time, he enjoys collecting records, especially those that are locally produced in Illinois.

Dr. Susie Wall

Dr. Wall joined the Palos Animal Hospital team in 1997 and has enjoyed working with animals and the people who love them ever since. She also loves the close relationships that she’s formed with them and being able to help pets down the road to wellness. Dr. Wall earned her Doctorate of Veterinary Medicine from Ohio State University and is affiliated with the American Veterinary Medical Association, Illinois State Veterinary Medical Association, and Chicago Veterinary Medical Association. She is married with three kids as well as a “pet child,” a golden retriever named Milo. In her spare time, she enjoys reading, traveling, cooking, and spending time with family and friends.

Dr. Deirdre Sheperd

Dr. Sheperd has been part of our team since 1995, after graduating from Purdue University in 1993. When she’s not caring for pets at Palos Animal Hospital, she cares for her own pets: a bichon/miniature pinscher/beagle mix named Bernard, a golden retriever named Paddington, and a German shepherd named Champion. Some of her outside interests include spending time with her husband and twin daughters, traveling, and spending time outdoors.

Dr. Sarah Turek

Dr. Turek earned both her undergraduate degree and Doctorate of Veterinary Medicine degree from Purdue University. She completed veterinary school in 2007 and began working at Palos Animal Hospital the same year.
