AWC is very clean, the staff are always friendly, and Dr. Siek is wonderful. Our kitty had two surgeries recently, within a month of each other. When we realized we needed the second one and our kitty was in much more pain this time, Dr. Siek got a surgeon lined up for Wallace within days and provided her same level of excellent care throughout. She is obviously an animal lover, which I think is a very important quality in a vet. 

Thank you Dr. Siek and we will refer anyone who asks for a good vet to you!!

Superb!  Recently, our German Shepherd developed a scary looking and painful condition on her back.  Panicked, my wife called AWC and Dr Cosgrove got her an appointment 12 hours later.  She is on the mend now (she still barks at squirrels outside the window, though).  We've had to call on Dr Cosgrove many times (we have 2 dogs) and he has provided excellent care for us every time.  Highly recommended.

I was so amazed by the level of care and attention he [Chino] received from the entire staff. I am happy to say that almost 6 months after his FCE he is a new pug! He regained full movement in his back legs and is able to do everything he did prior to the FCE, all thanks to the therapy he received..
