I would highly recommend the Whitman experience to anyone who is interested in learning with extremely driven individuals, values a broad based liberal arts education, and looks forward to having easily accessible professors.
I would--and frequently do--recommend Whitman very highly. My time there was one of the very best experiences of my life academically, socially, and intellectually.
Whitman's greatest drawback is its location; Walla Walla is pretty far from urban centers and their advantages. Many people do not find this to be much of a drawback at all, though. There is a great deal of outdoor activity to be done in and around Walla Walla, and the 3 colleges in town bring a surprising amount of culture to bear.
One of Whitman's greatest assets is the sense of community you will find there. To a certain extent, this is true of liberal arts colleges in general, but Whitman is especially close-knit and the faculty are especially involved and accessible to the students. This creates and fosters a learning environment that is unique in the region and holds up well against any in the country. In my own experience with graduate study after Whitman, only students from Swarthmore and Amherst were as well prepared as I was.
