He was worth every penny

Jon is a great lawyer and goes the extra mile for his clients. I was very impressed with his knowledge in law regarding my case. I have worked around attorneys for the past 5 years and Jon was highly recommended to me by another attorney who is a personal friend. Jon not only knows the law inside and out, but also the courts personnel which is very helpful in determining your best outcome. He also gives the client opportunities to make choices based on his prior engagements with the courts citing case law and other attorneys experiences. He is also well respected by the other local attorneys, I can’t say enough good things about him. If you need an attorney in the surrounding area he has a vast network of experts and colleagues. He was worth every penny, even if you have bad luck and go up against a lean and unpersuasive judge. The courts are a gamble and I don’t gamble, narrow down the odds with Jon on your side.

Jon, thank you for giving my life back to me

I’ve been in and out of the court system since I was 14. I am now 26. My last conviction was at 19 years old. 11 felonies, and convicted of all of them. I made a stupid mistake and because of my extremely extensive record, my guidelines were 2.5 – 3 years. Jon is the best criminal defense attorney I have ever come across. He may not show it in your face, but when it’s time for court, this man is ready at preliminary as if it’s trial. My 4 charges were all DROPPED that day. I have never had a charge dropped in my life. I always take a plea or probation. Jon took 10 extra steps and relentlessly followed up on tiny things others wouldn’t. After all was said and done, the judge looked at the arresting officer and prosecutor in a way as if to say “do you even know what you’re doing?” Jon, thank you for giving my life back to me.

Jon came through as always

Jon represented me for an assault charge during COVID. The case was reduced to disorderly conduct do to his excellent maneuvering during trial. I very highly recommend Jon for an attorney.
