patPat Davis , D.V.M.
Being an Air Force brat it is hard to say where you are from, but I was born at Patrick AFB in Florida playing on the beaches and watching missiles catapulted into the heavens. I lived the longest in Clovis, New Mexico-home of tumbleweed Christmas trees and an abundance of dust storms. I had a wide variety of pets growing up (though my mom drew the line at skunks and snakes), enjoying each and every one. My passion was horses, and still is today.

I married my husband, Jimmy Davis, while he was in vet school. Many years after his graduation, I decided to go to vet school. I attended LSU my first year, then ended up transferring to and graduating from Auburn University in 2000. (It’s hard to go to one school when your spouse is military and moves frequently).

We have lived in the Killeen area since 2000 with a brief hiatus when the military sent us to Monterey Bay, California. We have two children, Ashley and Jordan. We also have a menagerie of dogs, cats, cockatiels, horses, and chickens, as well as some fish.

leeW Lee Erwin , D.V.M.
Dr. Erwin, a native Texan, spent most of his early years in the Houston area. A graduate of San Jacinto High School, he received a Bachelors and a Masters degree in Physics and Mathematics from Stephen F. Austin State College in Nacogdoches, Texas. He was employed on the faculty at Central Texas College for 4 years before attending Texas A&M University to study veterinary medicine. After graduating from The College of Veterinary Medicine at Texas A&M University in 1975, Dr. Erwin began his career in veterinary medicine in Killeen. In 1976, Dr. Erwin opened Southside Animal Clinic (later to be renamed El Centro Pet Medical & Laser Surgery Center) at its current location on South W.S. Young Drive where he has since practiced. In his 35 years of practice, he has had the privilege of watching hundreds of pets develop from new born to old age as well as their off-spring to do the same through several generations. Dr. Erwin also highly values the many long-term friendships with the families of all these pets that have developed over the years. Dr. Erwin transferred ownership to his long term colleague Dr. Pat Davis and assumed the role of Associate Veterinarian in 2009.
