Chicago personal injury attorney

So my cousin just moved out to Chicago, the windy city i believe its called lol......so i was asking him why and he said that he is going to be a Chicago personal injury attorney apparently there is a demand for them or something LOL....But i'm not sure if they are going to be a Chicago personal injury Lawyer, or a Chicago personal injury Attorney, isn't it the same thing?  well good luck to him i'm sure he will do fine since we do have judges and lawyers in the family hehe
