About Us

Welcome to Sierra Madre Animal Hospital! We are located at the corner of Michillinda Avenue and Sierra Madre Boulevard in Pasadena, California. Formerly Hastings Animal Hospital, Sierra Madre Animal Hospital was established in November, 2013 when Dr. Walter Cailleteau purchased the hospital. With an all new staff and an extensively remodeled front office, we are delighted to be serving the Sierra Madre, Arcadia, Pasadena, Hastings Ranch and surrounding communities. Dr. Cailleteau has over 20 years of experience practicing veterinary medicine and surgery in Southern California and all of our staff is highly trained.

Sierra Madre Animal Hospital is an advanced, full service veterinary hospital with a reception area, three examination rooms, a surgical suite, digital radiography room, treatment room and pet boarding areas. The reception area, front desk, exam rooms and restroom were completely renovated and provide the hospital with a clean, inviting and calm environment for all our patients and clients. We are open Monday through Friday from 8:00 am until 6:00 pm and Saturday from 8:00 am until 12:00 pm.

At Sierra Madre Animal Hospital, we are dedicated to providing personal, honest, affordable, high quality veterinary medicine with the best customer service around. Our goal is to continually upgrade and improve the veterinary services and appearance of the hospital while continuing to care for all our patients as members of our own family.
