welcome

At Sunset Veterinary Center, Dr. An and staff strive to provide compassionate and excellent medical, surgical and nursing care. We understand pet-parenting comes in all different shapes and forms, and our goal is to offer honest recommendations tailored to fit any parenting method and budget. 

We acknowledge the value of your time and we focus on providing prompt medical care and diagnostic results for your busy lifestyles and pet’s urgent medical needs. We uphold many wholesome traditional values and we treat all of our patients and parents with kindness and respect. 

We are here to educate and bridge the gap between pet-parenting and modern state-of-the-art veterinary medicine and pet care. Ultimately, we keep your pet’s best interest in mind and work collaboratively with you to make the best informed decisions.

Dr. An and staff have set their standards higher and look forward to serving you and the Diamond Bar community!
