William C. Stone, DVM, MS, MBA, Diplomate ACVS

Owner and Lead Veterinarian


Dr. Stone (Bill) is a native Texan, born at Fort Hood, Texas a few yesterday’s past.  He spent most of his formative years in and around Houston, where he attended St. Thomas High School.  From there his blood turned Maroon and White at Texas A&M where he received his Bachelor’s degree in Animal Science followed by his Doctor of Veterinary Medicine.  He interned at the University of Tennessee – Knoxville in Large Animal Medicine and Surgery.  Upon completion of the internship he returned to Katy, and became an associate at Katy Equine Clinic, owned and operated at the time by Dr. Mike Heitmann.


His interest in a surgical specialty took him to Wisconsin for a time.  While there, he received a Master’s Degree in Veterinary Science, and became a Diplomate of the American College of Veterinary Surgeons.  He stepped away from the university and built a referral surgical hospital in Delevan Wisconsin, which he operated with a veterinary group for 10 years.


After spending enough time in Wisconsin to understand how cold things can really be, he started making the move back to Texas as a consulting specialist at Dr. T’s Equine Clinic.  He made the permanent return to Texas in 2010 when he accepted a position at Katy Equine Clinic – back where he started.  In 2016, he purchased the practice from the group in Florida, and is now building a great team of horsemen and women with pride in horsemanship and quality veterinary service from wellness care to complex medical and surgical concerns.  Dr. Stone returned to Texas A&M in 2015, enrolling in the Executive MBA program receiving his MBA in May 2016.


Dr. Stone’s hobby list is pretty short, but then again, he is lucky enough not to have to go to work every day!  He has two children Zach, who completing his residency in Orthopedic Surgery at the University of Florida – Gainesville.  Tiffany, also a veterinarian of the Florida variety, practices in a small animal practice in Houston.  Between the Doctor’s Stone they can fix your horse, your dog, or yourself!

Support Staff

An avid horseman from the get go, her momma couldn’t keep her away from the ponies.  Lucille ran barrels and still occasionally wears the buckle she won in competition.  Her daughter followed right in her footsteps.  Lucille’s mantel is full of her daughter’s trophies competing in FFA and rodeo speed events.

Lucille has been married to John Estes for over 38 years.  And they’ve been customers of Katy Equine almost as long.  They have two pampered retired horses, April and Aurora and have just acquired a new horse, Peanut, that is making Lucille look forward to being back in the saddle again.  “Just for trail riding”, she says.

She’s a Texas country girl and embraces all that it means.  She takes care of Katy Equine with her heart and soul.
