In my short tenure at Berklee one of the things that has impressed me the most is the Alumni Network that Berklee embraces.
I have attended alumni events at the great schools that I attended and there may be a couple of dozen people there. Attending a few of the Berklee events around the country I was blown away by the HUNDREDS of grads in attendance, and the connecting and networking happening!!!
I noticed that Berklee grads embrace each other in a very real way, and support each other. Like Danny said above, the students in your class will be the ones hiring you and visa versa when you get out. I still work with musicians that I went to school with 30 years ago, they get me on gigs and visa versa.
I also know that Berklee has a very vibrant Alumni Affairs program that leads off like this…
"The Office of Alumni Affairs embraces our alumni as valuable members of a lifelong and global Berklee community. We strive to foster alumni engagement that supports you in your professional and personal pursuits. As one of our alumni, you are an ambassador of the college, trailblazer in music and beyond, and a generous supporter of what we do."
