Look them up in Martindale-Hubbel. It is a rating system that is based on peer evaluation. It does not show success rates for cases, but it gives them a grade like av, bv, and cv. They av and bv rating is very good, cv is average. Go to Lexis.com, or Martindale-Hubbel.com. Also, if there is a law school near by, they will have a Martindale Hubbel book.
