Doberman Pinscher

Can anyone direct me to a few reputable kennels that have fully trained PP dogs?  I'm trying to help a friend out in finding the right dog.  He is in an industry of being "high profile" and would like an estate dog.  He prefers a male, socialized, who's lived in the house. 3-4 years of age.  I apologize in advance I am not knowledgable in Dobermans.  I have GSD's.  He has allergies and a German Shedder is not an option for him. lol  Feel free to PM me.
