I'm looking for info regarding the Presby/St.Lukes vs Norhtern Colo (Greeley) programs (externship and residency). Specifically, I would like input from students that have externed or visited these programs. Why/why not did you rank these programs. Was the externship a good learning experience? After the externship/visit were your expectations exceeded/met/not met? Strengths/weaknesses? Any input would be greatly appreciated, thanks.
