It's not hard to find a Social Security law professional, but don't let that make you become complacent in your search for one. You'll still have to sample the wares for a while before you find the right one for you. It's all a matter of affordability, compatibility, and experience.
As with any professional you have to work closely with, you should be comfortable with your Social Security law advisor, be they lawyer, financial planner, or otherwise. If you don't work well together, it could end up affecting your judgment and your lawyer's.
