Based on the anecdotal feedback of a resident who i met that did her prelim here, it was not a cush program. She said she frequently was challenged by the complexity of patients and had to stay late. Just looking at the schedule there is a total of 1 month of night float, 4 ward months of medicine. There are about 3 months of electives which is pretty decent chunk, but I'm unsure about the hours during these electives.
That being said I look forward to interviewing here because I have family that works at Lahey and I know it would provide a first rate education for internship
