    Terrible experience. My cat has an early stage heart condition with cardiogenic pulmonary edema. She was only showing a mildly increased breathing rate of about 40 per minute without any other symptoms. Seeing her doing ok, instead of focusing on the real issue, the clinic tried to overcharge me for unrelated tests and meds. Her X-ray clearly showed an enlarged heart and signs of fluid in the lungs, yet the vet refused to provide even basic diuretic treatment. She insisted on waiting for the radiologist review and suggested it might be pneumonia. She also promised to call me with the radiologists report, but never did because she was off the next day and simply did not follow up. When I called the clinic, the receptionist said the vet would not be back until next week. When I asked for the next step and requested a diuretic prescription, the on duty vet refused and told us to go to the emergency room. If it were truly that urgent, they should not have sent us home without any treatment. They even claimed only a cardiologist can prescribe Lasix, which is completely untrue. I contacted a cardiologist’s office and a cardiology nurse later confirmed this. She was shocked they refused to prescribe diuretics. She even called this clinic herself to explain that any general vet can prescribe Lasix, yet they still refused. We ended up having to bring our cat to a different clinic who was willing to see her the same day. Another regular vet, with no specialty, reviewed the exact same X-ray and immediately prescribed the correct medication Lasix to help with the edema. This clinic avoided responsibility, pushed unnecessary charges and failed to provide basic care. I do not blame the receptionist, but the vet’s lack of knowledge and their uncaring, unprofessional and irresponsible behavior put my cat at risk. I would not recommend this place to anyone with a sick pet.

    We have an 8 year old pit-bull. The nurse was very patient. Doctor was very honest. Their pricing is very fair.

    Dr. Ahn exhibits good dog energy and has a generally calming demeanor that makes an appointment as anxiety free as possible for our pooch. She is thorough and sticks to necessary procedures without adding extraneous services to boost the bill.
