Hello,
I do not know of this vet, but I did do a little bit of searching. His dogs have been in a number of dog shows, for whatever that is worth.
I would be curious to hear what you find if you do get in touch with him. I actually work in the town where he is listed, and I'd also be curious to know where he works. If I ever needed a backup veterinarian, it might be good to use someone who knows a lot about Yorkies.
Good luck, and if you don't mind sharing your experiences, I would love to hear them.
