@FNP2B1210 hello! I had a great summer at Sinai this year and I really loved the environment! I ended up as an intern on the CCU, where there was no shortage of hands on activity and working at a similar level to your mentor. This year, the application opened and closed within the first week of March, and that’ll be your short window of time for applying- it’s not a super well known program, but they really love to keep all of their interns post-grad, especially if you worked in Heart Hospital or related to Peds.
