If you live in SAN MARCOS or the surrounding area and need a trusted veterinarian to care for your pets – look no further. Dr. Todd E. Sebby & Dr. Mark E. Williams are licensed TX veterinarians, providing dog boarding and pet grooming. Your pets’ health and well-being are significant to us, and we take every possible measure to give your animals the care they deserve.

Williams-Sebby Veterinary Clinic & Pet Resort is a full-service animal hospital and welcomes both emergency treatment cases as well as pet patients in need of routine medical, surgical, and dental care. Our Doctors have years of experience treating severe conditions and offering regular pet wellness care. Beyond first rate pet care, we make our clinic comfortable, kid-friendly, and calm, so your pet can relax in the waiting room and look forward to meeting our SAN MARCOS veterinarian.

We provide a plethora of services for your pet’s unique needs. Whether they need routine care, annual exams and shots, treatment for minor injuries, seasonal allergies, or are in a major medical emergency. We take pride in our commitment to provide a state of the art hospital for all of your pet’s needs. Our brand new on-site boarding facility best demonstrates our commitment to high quality care. Why choose us for boarding? Because we will address every facet of your pets well being during their stay with us; this includes cat condos, large kennels, a spacious yard with a dog bone shaped swimming pool, no charge medicating, and a dedicated staff to provide caring companionship during their stay.

In addition to our veterinary care staff, we have an on-site groomer and dog trainers. Our superb grooming staff can provide your pet with a fresh haircut, bath to toe nails, and even a facial. Your baby deserves a spa day too! Whether you want your dog to look prepared for the yearly family photo, or dog show ready, our grooming staff is prepared. Our dog trainers offer a wide range of classes for pets of all ages, predisposed behavior, and breed. These classes include puppy training, basic and advanced obedience, bad behaviors, and many, many more. The training we offer is so effective that we even train service dogs.

We are happy to offer many resources that enable you to learn about how to take better care of your pets. Please feel free to browse our site, particularly the informational articles. The best veterinary care for animals is ongoing nutrition and problem prevention, so becoming knowledgeable about preventative pet care is essential to the continuing success of your animal’s health.

  • "I love this clinic. Staff has always been kind and they are great with my dog. They always fit me in and I've never had to wait long between the waiting room and actual visit. I moved a few months ago and am sad that I have to find a new vet. Thanks for the great service for almost 5 years!"
    Kirsten Hettinger
  • "This has to be the greatest vet ever!!! Called them because my outdoor cat came home (after his 4 nights out partying) tore up really bad. They were very understanding and got me in right away. Wait time was only a few minutes and everyone was very kind. I was very worried about how much it was going to cost but I have to say that it was very reasonable."
    Monica Fisher

  • "I love this clinic and have been taking our pets there since I was a toddler! Both docs are amazing and the prices can't be beat. They have cared for all of our animals both large and small and are always very helpful during office hours and when I've had to call after hours. I would NEVER consider going elsewhere!"

  • "Hi, y'all! My name is Lauren and my almost 10 year old mini Yorkie Ginger is the absolute LOVE of my life! We have had numerous vets over the years and without a doubt the folks at Williams-Sebby set the standard for vet care! From the moment you walk in the door, the entire Williams-Sebby crew are there to make you feel at home. Their knowledge, expertise, and LOVE of all animals is top notch & I'm forever grateful for the love you've shown to my precious furry person. <3"
