  • Jonathan L Katz

    If I needed a criminal defense lawyer in Northern Virginia, John would be among the first I would call. John is at once fully committed to criminal defense, and calm in dealing with opposing lawyers. John has been very kind in the past when I have discussed some challenging matters in my cases with him. He was one of the first area criminal defense lawyers I met before I entered criminal defense practice over twenty years ago. I deeply appreciate John for his excellence and kindness.
