IVAH is fantastic. Dr. Spense always takes the time to properly answer any and all questions and makes sure to explain any issues in a way that is accessible to the average person. All the assistants at IVAH are equally helpful and supportive.
My cat has numerous problems that my previous vet couldn't diagnose. After too many visits and no answers from my former vet, I was relieved when Dr. Spense was able to diagnose the issues on the first visit. She's like an animal detective with a bunch of friendly sidekicks.
Cost wise, IVAH is pretty standard for the area. There are a few less expensive vets in close proximity, but, if my experience is indicative of anything, you'll end up spending more in the long run on the less expensive vets because they won't take the time initially to actually figure out what's going on.
