Service exceeds the cost! Catherine will put you on the treadmill and provide a diagnosis that will literally fit your feet. Very knowledgeable, helpful and friendly service is what we received from Catherine and the other staff members.
POSITIVE

Yep, from five stars to one! It appears that this clinic is only courteous when you have a bottomless Scottsdale wallet. Otherwise, they browbeat you into feeling like the worst pet owner ever, even when faced with an Impossible end-of-life situation.

This update is written two years after the beloved pet in question passed away, so is by no means a grief-stricken, heat-of-the-moment review. For compassionate care, I now recommend Scaredy Cat.
NEGATIVE

Did the owners change?? I have been to this place around 8 times and all times except for the last one - the food was AMAZING! Great pho, especially their sate pho. The last time I went, about 3 weekends ago it was different and horrible. The service was lacking (none of the people who were working I recognized); got my order wrong, then I waited a while for my sate pho, and they gave us a small quantity of bean sprouts and basil . The sate pho was very different, not enough spice, the broth had no flavor, the meat was very different than what it usually is (it was a very bad quality cut of meat); I didn't even finish it. What happened Sammy Pho? I'm very disappointed.
