I know Farley D Havanese (Terry and John) are in PA and Suzanne and Pat who co-own some Fantasy dogs are there too, but can't think of their kennel name but Terry often handles their dogs. Ernesto Lara is a professional handler in PA who shows Havanese as well as other breeds. Oh, just thought Pat and Sue's kennel name is Glen Iris. The Lawerence's of Fuzzy Farm are in CT. The closest breed club would be The Greater New York Havanese Club;
www.gnhc.org. I'd contact them first and go on from there.
