  • Michael Martin Hanis

    I'm a little prejudiced as Brian is not just one of my partners, but also one of my sons! He has matured into a fine lawyer with superb skills, particularly in the areas of helping people with debtor/creditor, bankruptcy, landlord tenant, and personal injury issues. He takes excellent care of his clients, and I would never hesitate to refer an important client or case to him. I am proud to endorse him.
