Dr. Evan Kirk’s interest in veterinary medicine came at an early age when he would accompany his dog on visits to Dr. Joseph Brewer, founder of Brewer Animal Hospital. This experience eventually inspired him to attend the University of Illinois, where he earned his veterinary degree, and then back to the place where his dream was first sparked.

The Springfield native is a past-president of the Board of Directors for the Animal Emergency Clinic of Springfield. He also wrote the popular “Ask the Vet” column that ran in the Animal Protective League’s quarterly newsletter.

Dr. Kirk and his wife, Mary, have two college-age kids, Bryan and Julia.  The Kirks share their home with two cats named Lola and Willie, and one dog, a mixed breed rescue, named Suki. In his spare time, Dr. Kirk enjoys gardening, bicycling and boating. 

His professional focus is on surgery and internal medicine of dogs and cats. His professional goals are to provide the best quality medicine available for his patients, great service for his human clients and a safe, enjoyable and rewarding workplace for his team.


Dr. Ward graduated from the University of Illinois’ College of Veterinary Medicine in 1991. She joined the staff at Brewer in 1995 after first practicing in a mixed animal clinic in Sandwich, Illinois.  Dr. Ward has a special interest in exotic animal medicine, which she frequently practices here at Brewer.

Dr. Ward shares her home with a cat named Frankie, which was rescued through our clinic, a Walker Hound named Dulcie, and a lab mix named Stella. Stella is the newest member of the family. She was adopted through our clinic from Pets Without Parents of Mason County in 2016. She is a lively pup that is giving Dulcie a run for her money!

In her free time, Dr. Ward enjoys traveling abroad, baking, shopping, and spending time with her family. She is also a member of the local chapter of the Zonta Club, and organization for professional business women. 


Dr. Kiley graduated from the University of Illinois College of Veterinary Medicine in 2014.  She is originally from Shelbyville Illinois where she grew up working for Dr. John Brix at Brix Veterinary Service.

Dr. Kiley and her husband, Jack, live with their two rescue dogs, Louie and Bernie.  Louie is a terrier mix who loves everyone, especially anyone who is giving Bernie attention. Bernie, a lab mix, happily shares the love with his buddy Lou.

In her spare time, Dr. Kiley enjoys traveling, cooking, playing volleyball and cheering on the St. Louis Cardinals.  She is currently (and rather unsuccessfully) learning to play golf, but mostly loves any reason to spend time outside.


Dr. Thornburg retired from our clinic in 2014 and is still very much a part of the Brewer Animal Hospital family. Dr. Thornburg began his career as a student intern in 1979 under the late Joseph Brewer, DVM. He joined the Brewer Animal Hospital staff as a full-time Veterinarian a year after graduating from the University of Illinois School of Veterinary Medicine. He later became clinic owner upon Dr. Brewer's retirement in 1995. His specialty was in animal reproductive medicine.

He is a past President of the Capitol Canine Training Club, and a member of the Sangamon County Animal Control Board. He remains active with both.

In his retirement, Dr. Thornburg is enjoying spending time with his wife Pam on the several acres they own just outside of Springfield. They keep themselves busy with their two Rottweilers, Tizzie and Belle, by taking them to tracking events and dog shows. The Thornburgs also share a love for all things equestrian, and have several horses that they take riding frequently. In his time with Brewer Animal Hospital, Dr. Thornburg established a large clientele of devoted pet owners that still ask about him almost daily. It's always a pleasure when Tom stops in to see us and say hello!
