I work at Children's and we have four primary ENT's there and they are all excellent. Dr. Wiatrak did my niece's T&A, Dr. Woolley and Dr. Hill are also great! I'm not as familiar with Dr. Shirley, but I don't know anything negative about him.
Here's a link to all of them:

Many of Children's docs travel all over the state to provide services at different clinics. Not sure where you are or if any of the ENT docs travel, but before you drive to B'ham you may want to ask if any of them come to your area.
