Greater New York City Area
You are from my hometown! I was born and raised in Saint Augustine and I still have several relatives there. It's a beautiful city and I miss it. To answer your question, to be a good entertainment attorney you need to be passionate in that field. To start, you need to earn good grades, attend a reputable college, and a decent law school. While you are in college and in law school, you should look for internships in the entertainment industry. Internships are a good way to become familiar with a field and to make connections. In law school you will choose which electives you wish to take. These electives will help you prepare for a career in that area once you are an attorney. Of course, if you are serious about becoming an attorney in such a specialized area, you will benefit from moving to an area where there is more of a demand, such as Los Angeles, Chicago, New York, or Atlanta (to name a few).
Good luck with your studies!
