Well, just googling his name, came up with this, perhaps someone will come in during the week who may have some experience with him.
here is the link :
Nicholas Valenti: ZoomInfo Business People Information
there is more than one person of that name or he is involved in more than one kind of buisness. I don't know I didn't click on them to find out.
Dig up some good breeder questions and ask him about his dogs and listen to what he has to say or ask his receptionist when would be a good time to call and talk to him about the dogs he might have available.
Good luck!
