Laura has been with our hospital for three years. She is here every Thursday and Saturday and a few afternoons when we need an extra hand! With 22 years of experience you can count on her to answer your questions about anything you may need. She is a tremendous help and will make you laugh! Laura and her husband, Les, live in River Mountain Ranch with one horse, one cat and a mini Aussie named “Flea”.


Christine joined our practice in the Spring of 2013 after moving here from California. During her first two years she worked part time assisting with surgical and dentistry procedures and remained with patients during postoperative recovery. Since then, she is now at the front desk and frequently steps in for examinations. She is a licensed veterinary technician with 30 years of experience and exceptional skills. You will find Christine to have endless patience and is kind as the day is long. Although she is not here often, she plays a vital role in helping us during busy times or when we have special cases that require extra care. She lives in Boerne with her husband, Shawn and daughter Jessie. They share their home with a rescue Yorkie mix, a Pyrenes mix, 2 cats and 6 chickens. Christine enjoys horseback riding in her spare time.


Sean is off to college. Hard to believe he started here with his 4-H group when he was 11 years old. He will return on occasion to work, or mow the lawn for the clinic because he needs spending money. I can honestly say, he will be a great veterinarian if he completes that journey.
