Frank and Mike are great, and as mentioned, very accomplished professional field trial trainers. They know and have trained with the best and tutored some of the really good upcoming trainers. I go out there with my dog regularly, meaning she doesn't stay out there, but I take her out there and go train. Frank, more than Mike, works with me directly. However, Mike is always around to help as well. He teaches me how to teach/train a dog.
They're awesome in reading dogs and figuring out what makes them "click".
I'd suggest going to talk to them and watch them work with their dogs. I think you'll be impressed.
