What Our Clients Say

"We had him as a public defender for my father. He kept in contact with us, worked with us, and actually did his part as a defender. I can't say enough good things about his work ethic, his commitment, and his dedication to prove my father's innocence. We owe him so much for what he has done. I absolutely recommend him."

"R.J. Dieken has been beyond supportive and helpful as we are going through a very difficult situation with my boyfriend and his sentencing and a possible clerical error. He has been very informative, incredibly down to earth, very empathetic, and incredibly supportive, and very willing to help us figure out a solution. He has also been willing to remain affordable and be reasonable and work with us given our situation. I would definitely recommend him to anyone in a difficult legal bind."
