My wife and I cannot speak for everyone at Sienna Animal Hospital. We can, however, speak for Dr. Allala. We first met Dr. Allala at Flamingo Pet Clinic. We were a little weary at first, but that quickly subsided after we saw how well Dr. Allala handled our animals. We have a dog who has a liver shunt and is scarred along her entire chest and stomach. We were pleasently surprised at how much Dr. Allala knew. She informed us that our dog is susceptible to patella luxations due to the breed of dog. After about a year or so we noticed our dog becoming more aggressive to our other dogs. Dr. Allala checked our dog and recommended knee surgery. After we decided to get the surgery and after recovery, or dog is no longer aggressive towards our other dogs. If you are looking for someone who will be kind, caring, affectionate, sensitive, and highly educated, then I suggest you go see Dr. Allala!
