    John Kuczek, DVM


     Dr. John H. Kuczek takes great pride in being a Killeen native and he returned to the area after graduating  from Texas Tech and Texas A&M College of Veterinary Medicine. He established a mobile large animal practice that he operated for 7 years.

       Wanting to broaden his experience he accepted a position on Fort Hood and spent 7 years as the veterinarian for the First Calvary Horse Detachment, the Fort Hood Veterinary Treatment Facility and for the Military Working Dogs.

      On 16 April 2016, Dr. Kuczek and his wife, Emily, assumed ownership of Aztec Pet Hospital. Dr. Kuczek immediately expanded services to include a wide range of surgeries and dental procedures. He is very passionate about internal medicine and critical care. He seeks out educational opportunities as well as investing in the latest technology to ensure our clients receive the highest quality of medicine possible right here at Aztec with the Doctors they know and trust.

       Dr. Kuczek enjoys driving his vintage tractor with his two year old son, Jackson. He also spends his free time fishing, cooking, watching science fiction movies, and he attempts to shorten the "honey-do" list at home.





    Meagan Sims, DVM


    Dr. Meagan Sims joined Aztec Pet Hospital in May 2019. She is from Midland, Texas where she grew up on a small hobby farm and  worked as a vet assistant as well as on the kennel staff of several clinics. She holds a degree in Biomedical Science and a Doctorate in Veterinary Medicine from Texas A&M University.  After graduation she worked as an associate veterinarian at a small animal clinic for 2 years. We are fortunate to have her on our team here at Aztec.


      We asked Dr. Sims what she loves about working at Aztec and she responded that she enjoys working with her "sweet patients and engaged and caring clients". She appreciates there is a wide variety of cases which means there is never a dull moment.


      When not at the clinic, Dr. Sims and her husband, Josh, can be found with their 3 dogs and Red the chicken. She enjoys hiking, sewing, watching football, gardening and reading fiction.
