I have had dogs and cats for 40 years, and have used vets in multiple states. Dr. Winnie is by far the finest vet I have found. I have been using him for the last 10 or so years, and he has treated several dogs and cats for me. He is a great diagnostician, and always takes time to thoroughly explain what he is doing and the results of any test. He demonstrates concern for animals well being while at the same time not applying pressure to use extraordinary measures in complex cases (though he always offers the option).
An anecdote of his diagnostic acumen: I recently brought my mothers dog to live with me after she moved. This dog had recently been to her old vet (one considered a fine vet in that area). I took her to see Dr. Winnie just for a check up and he found one issue overlooked by the other vet, and recommended a different course of action for two relatively minor existing issues. While I'm not a vet, I found his explanations for his suggested treatments compelling.
To summarize, I've always been very satisfied with the treatment he provides and have always found visits enjoyable.
