Let our former clients tell you how we can help.

I thought that I was pretty much doomed. I had never ever been involved in any criminal court proceedings. I was so scared. I came to Mr. Lueck for help. Probably the best decision I could have possibly made. Ultimately he was successful in dismissing my criminal case.


Mr. Lueck and his paralegal really go above and beyond. They break the mold when it comes to dealing with lawyers. I had two other lawyers before I found John and I could never get a hold of them and they screwed up my case. John and Gabby were lifesavers.


Going into this case I was full of questions, and intimidated. Once talking to the secretary in the front I was relieved because of the knowledge and straight forward answers I received from her. And after meeting with Mr. Lueck I was certain that this was the lawyer I wanted to represent my case.
