Because of the tremendous amount of trust placed in him, Mr. Nathan D. Isen provides admirable art authentication and certification and has always found it imperative to satisfy his clients' many requests for information and assistance. The generous assistance he provided me has led to my discovery of how Louis Icart pieces, the genuine ones of course, can truly bring immense satisfaction to happy owners like me. As curator of the Louis Icart Museum in Philadelphia, Mr. Isen carries a huge responsibility towards those he serves, a responsibility that he capably carries on his shoulders as an art expert. Anyone can see that Mr. Isen loves what he does, and it is apparent in his cheerful way of assisting clients and answering their questions. He certainly made sure I was greatly assured of getting a genuine and duly authenticated fine art piece! The IBrewster Gallery carries a wide collection of exceptional art pieces, and Mr. Isen makes sure that visitors get to enjoy truly unique pieces at every visit, with fresh ones coming in regularly. I love coming to his gallery for wonderful finds! Dedicated to his job and fuelled by a strong passion for it, Mr. Isen counts himself lucky to be able to do something he has always been fascinated with, and that's art.
