Highly recommend! I reached out to Mr. O'Leary to try and get some legal advice. Before we spoke, he took the time to research the matter so he could give specific advice as to next steps to take. Very professional yet very personable as well.

I spoke with Mr. O'Leary today to gain some insight for a problem at hand. Though my particular situation was not his area of expertise, he still took the time out to listen to me and referred some resources of help. In our moment of conversation, he exuded professionalism, empathy and diligence. Would definitely recommend.
