“Patrick is knowledgeable and personable! I would recommend him to anyone searching for an attorney. He helped me obtain my teaching license in a timely manner.”

“Patrick was my attorney in my licensing issues with the state of Illinois and again with credentialing for BCBSIL. He was very attentive, available and hard-working, getting results from the IDFPR as quickly as possible. He understood what a grueling process this was for me and worked hard to get me practicing again. I’m very grateful to him and his support staff.”
