One long time member used to suggest going to some wc hearings to see the attys in action, and to talk with the claimants that are in the waiting area.
To see if they are happy with the ones they have or not.

If you have a serious long term injury and pain it might be worth the time to do that.

If that isn't possible - interview with as many as you can to get a real feel for them & the staff - if the office/staff is disorganized or not professional - most likely the atty is the same. IMO

I wish someone would have told me that bit of information.
