I'd try talking to your dentist. Maybe he will be able to recomend one to you. That's how I found mine.

He really did a great job making me feel comfortable, which was really helpful since I was so scared. I work in a hospital cafeteria, so I also talked to some of the doctors and nurses there and many of them recomendeed the surgeon I went to. Also you might want to talk to some of your friends and find out about their experiences with different oral surgeons, when I did this I found out that almost everyone I know has been to an oral surgeon at one time or another and many of them gave me some very helpful advice.
