Not sure if having a "trained professional" as a curator would eliminate personal taste which is inherent in selecting, buying, and exhibiting art. I do think that having a curator trained in business would help. A good example is the man who ran the Honolulu Academy of Arts who recently left to take another position. He did an excellent job of using business acumen to make programs at the museum more efficient, eliminated programs that were not popular and too expensive, and improved the Museum and its exhbits while also running an efficient business.
