  • Henry S. Hilles, III

    I endorse this lawyer. I was opposing counsel on several cases when Jack was in the Montgomery County District Attorney's Office. He was always well prepared and represented the Commonwealth zealously and effectively. He is well liked and respected by his fellow lawyers and by judges as well. I would enthusiastically recommend Jack to anyone.
