I'm fortunate in that I've been offered placements in 6 different anesthesia programs. For that I am very thankful. The time has come to make a decision and move forward with my education. What is the most appropriate way to tell a program or program director that I have decided to further my education at another university? Should I call the program directors or just send a very professional letter via the regular US Mail? I would appreciate the advice of others who have been in my situation. The anesthesia community is very small and I don't want to burn any bridges before I even become board certified.

Thanks and Merry Christmas/Happy Hannukah, Happy Kwanza and Joyous Festivus to all
