Anyone have experience with Shelmar Kennels?

Hi! I have a 4 month old puppy and have to go away for work for 3 weeks when she is 6 months. I have pretty extensive dog training experience so she is about as good as she can be for 4 months, but I am looking for a board and train place to best utilize the time I have to be away. Price isn't really a factor, but integrity and kindness is. Please don't start commenting on how bad board and train is, because the right one works and I have had 4 immaculately behaved dogs love their trainer. That being said, I found Shelmar Kennels and it looked quite promising, does anyone have experience, positive or negative, using them?
