My list is somewhat short, but I would have to acknowldge Sean Bradley and Celia Chien first and foremost, as they menotored me when I first started out. Sean and Celia also have an awsome collection, and answer that phone call from me at all times of the day and night to answer one of my off the wall questions.
Secondly would have to be Brian and Lori Barcyzk. Two of the most genuine people I have met in the Business, and have one of the best collections in the world. I have bought numerous animals from them, and plan to buy plenty more exceptional animals from them.
