Always helpful.
I have used Mr. Tierney for all of my legal cases since 2014. From helping me with my divorce and child custody agreements, to speeding and traffic tickets, and recently criminal defense. He is always helpful, and I would recommend him to anyone.

Mr Tierney is eager to help
I was instantly relieved when I first spoke to Mr Tierney on the phone. My husband and I needed help dealing with a driving charge in Missouri and we live out of state. He was the first person I have talked to that is attentive and eager to help us. He is understanding of the position we are in and very very helpful. Sean was on top of it immediately, he answers our calls and messages quickly. And he is very easy to talk to. I appreciate his help and readiness to help us resolve the issue. I have no doubt he will help us put this in our past. Thank you!

Great divorce lawyer
A relative of mine recommended Sean and I'm glad he did. Sean did a great job handling all the details of my divorce. He kept me updated on everything and got me everything I wanted to get out of my divorce. Sean is also working with me on the payments so his services are affordable to me. Thanks Sean I think I'll use you for all my legal needs in the future.

Family Court
Sean did a fine job representing me in my custody, he was always quick with replys to all communication if he was not available at that very moment. He will walk you through everything and explain things in detail, as well as details on how the courts themselves operate. I will definitely use Sean for any other custody situations that may come back up.
