  • Jonathan Sol Harris

    I regularly trust Herman with my referrals. I exclusively practice personal injury and a criminal charge against one of my clients could really hurt the personal injury case I am handling. When one of my clients needs help with a criminal matter, I get Herman Martinez involved.

  • Carl Douglas Haggard

    I endorse this lawyer. I have observed him personally for 16 years at the courthouse as he advocates so hard for every client, every accused person and for every cause in favor of a defendant. He shows an excellent grasp of all areas of criminal defense and works tirelessly for every person in his care. His clients are lucky to have him in their corner because he backs away from no fight, yet always maintains his professional demeanor. I highly recommend him.
