    I have known Marcus for years and I refer to him anyone who needs a criminal defense attorney. I consistently hear from those I referred that Marcus did a great job for them. If Marcus can't help you, he probably knows someone who can, so he is a great first point of contact.

    I have known Marcus for many years and he is one of the most thoroughly prepared, and thus effective, advocates in town. I would highly recommend Mr. Debose to anyone charged with a crime.
