Used Erickson & Oppenheimer to represent me in a criminal case several years ago. They did not fight for me. They put all their effort into trying to convince me to accept a bogus plea bargain and none into my actual case. They were they were not looking out for my best interestand. They gladly took ...

After signing a $5000 retainer fee, Jon showed up in court twice during a two-year trial period. He didn't file any motions; he didn't do much of anything. He got his money and basically ran. I could have gotten a better sentence representing myself. Ido not recommend this attorney; he should be di...

Choosing a lawyer (most especially a criminal one) is never easy. I'm glad I chose Erickson & Oppenheimer to represent me. He does not come cheap- but do you want a cheap lawyer? They were outstanding from start to finish. Jon represented me in a Federal Criminal case out of state, resulting in the D...

Jon Won my case so I guess that's enough said!!! Sometimes some reviews need not say more but I will give you some specifics. He is very busy and I sometimes felt that I needed to be informed of what was going on but, I will take that all day long when the result is a win. He definitely knows what h...

Jon Erickson reminds me Perry Mason in the courtroom. I met Jon back in 2007 when I was in court with someone who I had been going to court with for over a year (because of attorneys who kept postponing the case and asking for more money). Anyway, I saw Jon in action for two days and he fought reall...
"Jon Erickson is one of the finest DUI defense lawyers in Chicago. He practiced in front of me for over five years when I was a judge, and for many years before that as a fellow defense lawyer. He was always a well-prepared, zealous advocate. He has handled several high-profile cases, including a murder case where the defendant ran over a cabdriver with his own cab. Those accused of crimes, including but not limited to DUI, would be well advised to retain Jon."
"I have known Jon Forrest Erickson for more than four years. Jon studies the issues his clients face in court, prepares an aggressive defense, and produces successful results for his clients. I highly recommend Jon to anyone needing assistance with a DUI. Bradley D. Birge', Esq."
"Attorney Erickson is a legend in the civil rights community. Due to his knowledge and legal savvy he has helped hundreds of people. You cannot go wrong with Attorney Erickson fighting for you."
"I highly endorse Mr. Erickson. Truly exceptional and caring attorney who produces great results in representing clients! I want all people with legal problems to contact him first."
"I endorse this lawyer.I have had the pleasure of knowing John Erickson since law school. We were classmates. He was a stellar law student. When other people were struggling to understand legal concepts he was shining. He especially grasped difficult subjects like Criminal Law and Procedure. More importantly, he was a wiz at Evidence. When other students wanted to understand these concepts they would ask Jon for help. He was a student's student. After law school Jon went on and received over 22 years of real TRIAL experience. He has handled sophisticated criminal trials with great success including murder trials. This is the equivalent of a doctor performing brain surgery. He now has become the lawyer to whom other lawyers come with questions. He has become a lawyer's lawyer. I am proud of the lawyer he has become, the person that he has always been, and to think that I am his friend. He is an advocate for his clients. He is their voice when no one will listen and no one hears them."
"I endorse this lawyer. Jon is both talented and compassionate. He and his work are highly valued in the Chicagoland legal community."
