Last I knew, most of the officers of the Western NY retriever club were pro trainers. Tammy Adsitt, her daughter Rene and Renes husband Sean Hagar. Not sure what county they are in.
If it were me, after watching them all run in hunt tests over the last few years, I would go with the mother, Tammy, as my pro and not the kids. She seems much more experienced and the dogs seem to respond to her better.
