No one responded to this question, which wasn't a big surprise -- the style of education (atelier) I'm looking for is geographically clumped: New York, California, Florence and Minneapolis.
I did, however, find a great website,
www.classicalrealism.com.
In particular, the site sells some inexpensive books aimed at this "traditional" style of realism:
"On the Training of Painters," by Richard Lack
"Twilight of Painting"
"Painting the Visual Impression," by Richard Whitney.
The site also links to a GORGEOUS gallery, the Gandy Gallery.
