Honest, Efficient and Exemplary

I needed a legal representation for a court date that was a very short notice, contacted Onello law firm and got a free consultation within a 1/2 hour and he was available for the court date on the same week. I was very pleased with his professionalism and genuine concern for my case and his honesty.... Thank you for representing me in a short notice.

Very helpful during a difficult time

I went with Onello Law Group based on their reviews, and they definitely live up to their reputation! My case should have been pretty easy, but due to some mishaps through the court and judge, it really became a mess! Vanessa and Nicole were phenomenal in helping to get this giant headache taken care... of. I would highly recommend them! They’re professional and responsive.

Guardian angel in the court room

5 Stars Attentive Accessible Prepared Knowledgeable Professional Great at what he does I am highly satisfied with Mr Onello representing me. I fired my previous attorney after 11 months due to; being out maneuvered by the opposing counsel, being mostly talk and no action, and other thing...s. Mr. Onello took over my case and immediately was caught up with my detailed situation. Then he put an end to the games opposing counsel was playing. Mr. Onello would always run all possible strategies, options and possible outcomes by me to keep me in the loop. Mr. Onello dominated the trail as much as an attorney could with his poignant questioning and precise objections. 5 stars! If you’re still unsure, give Mr Onello a call. I promise you, you won’t regret it.
