Sheridan Williford

Sheridan H. Williford - Account Manager

I first met Dr. Collins at Murray State College where my bride Kathy Williford was enrolled in the veterinary technology program. Later when Dr. Collins returned to private practice he hired Kathy as a veterinary technician and Practice manager. Sometime later Dr. Collins had an opening for an account manager; I applied and was hired for the position in late December 2005.

Kathy and I breed and show border collies under the name of Whistle-stop Border Collies. We attend numerous AKC conformation shows held in Texas, Oklahoma, Kansas and Missouri. All our border collies are under the care of Dr. Collins including puppies that go to their forever homes.
