About Huebner Oaks Veterinary Hospital

In case of an emergency, please contact our 24 hour facility, VitalPet Town & Country Veterinary Care Bandera Road Hospital, 10350 Bandera Road, Ste 100, San Antonio, TX 78250, 210-684-1448.

Huebner Oaks Veterinary Hospital was established in 2001. The hospital was formerly Colonies North Animal Hospital, which had been established in 1966. Dr. Marc Zieben graduated from Texas A&M University in 1984 and then came to San Antonio to work for Dr. Gerald Parker.  Dr. Zieben and his wife, Morna, purchased the hospital in 1990. Since then he has been the determining factor in turning the practice into the state of the art hospital it is today. 

Our knowledgeable staff is full of caring and compassionate animal lovers who all greatly enjoy their chosen profession.  Here at Huebner Oaks Veterinary Hospital we offer full service veterinary care, including vaccinations, preventative and emergency care as well as a full service boarding kennel. Our doctors are trained in all aspects of small animal surgery, internal medicine, radiology, ultrasound technology and endoscopy. Our clients and their beloved pet friends are always our number one priority.

My name is Crystal. I have been in the Veterinary field for a little over 7 years now and I love it. I can't imagine working in an environment without animals. Toby (our clinic bird) is very special to me. He loves animals as much as we do. I have a 2-year-old pit bull mix named Aiden who I took in as a stray and a 5-year-old maine coon mix named Sardine. I love to spend my free time with my husband John and our 6-year-old daughter Judith. I have been in the veterinary field her whole life so she loves animals just as much as I do and wants to rescue every stray animal she sees. For the time being she would like to be a Veterinarian when she grows up or a professional wrestler. I am pregnant with baby #2 and can't wait for her to join us.
