“As a solo attorney I do not have the overhead of comparable representation at a major law firm. That means no junior associates juggling your case, no layers of lawyers to get answers to questions. You work directly with me, start to finish. I file the motions. I draft the contracts. I litigate the cases. You will always have a one-on-one relationship with your attorney when you hire me.” — John McDuff
