  This is not my home vet, but when my Vaida (1 year and 7 month-old chihuahua) started vomiting and became extremely lethargic, the staff at Diamond Bar Vet Clinic agreed to see her despite having a full day. The doctor treated my baby’s severe dehydration and provided protective care against the vomiting and nausea and sent us home with some medicine. Vaida’s appetite returned the same night and her energy was back up. She hasn’t vomited since leaving the clinic. That alone would have been reason enough to leave a good review. However, not only did they show genuine care about my baby’s well-being, but they didn’t try to overcharge me. They penciled us in for the day, so we would only pay the routine exam fee rather than the walk-in amount of $90. The treatment costs were also reasonable. I would recommend this vet clinic to anyone in the area. Thank you to the amazing staff and the knowledgeable doctor at Diamond Bar Veterinary Clinic!

  Great customer service reasonable Pricing! Although the clinic was closing, they were able to squeeze us in. My daughter and I took our husky in with a prolapse issue. He did end up needing a higher level of care, but the staff was great and Tried their best without hesitation and with tender care to our pup. Will return for future care

  This place is a ripoff. The staff is incompetent and the prices are extremely high. The vet seemed inexperienced and very irresponsible. I spent thousands of dollars on unnecessary tests without receiving proper treatment. I ended up taking my dog to another vet to finally get proper care. A huge waste of time and money.

  I really question how Dr. Ahn and Dr. Choi are allowed to practice without accountability. I brought my pet in because something felt wrong, but I was told he was “fine.” Dr. Ahn’s only advice was to go to the ER if anything happened? I went in to prevent an emergency, not wait for one. I was charged over $1,000 for unrelated ear and dental treatments, which delayed proper care. My pet later passed away from a condition that was missed by Dr.Ahn. When I questioned them, Dr. Ahn was unavailable and Dr. Choi was extremely rude, only defending her. This was heartbreaking and unacceptable. After reading other reviews, I see I’m not alone. Please avoid this clinic at any cost.
