Mr. John Hartmann is a very professional person with great empathy. His transparency and honesty gave me peace of mind. I have known him for more than a decade. He is practically the family lawyer and I feel very grateful to him for having helped a loved one through a difficult and devastating process. It was there that I understood how a great lawyer can make a difference. It goes without saying that I have read his book twice. Without a doubt, he is a great human being. I genuinely recommend him.
