  • Robert Thomas Carpenter

    I've known Mike for a number of years, and have worked with him on matters within my practice for some time as well. He has the triple-crown of attributes as a lawyer that every consumer should want: He is intellectually gifted, very articulate, and highly ethical. He is a strong choice as a criminal defense attorney in my view.
