“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.”

Angelica R.

“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.”

“Patrick is an excellent attorney who will give you sound advice. He will not price gouge or exaggerate on the extent of his services they way other attorneys (especially in the Chicago area) will. He will work to resolve issues at the lowest level possible and is also available to answer any question you might have. If you have some issue, do not hesitate to call his office today.”
