Donald J. Hanrahan

Donald J. Hanrahan was born and raised in central Illinois. He attended Springfield College in Illinois (now Benedictine University), graduating with an associate’s degree in the top ten of his class. He then obtained his bachelor’s degree from the University of Illinois at Urbana-Champaign, and graduated from the University of Illinois College of Law in 1981. Having worked as a clerk for legal aid during his law school days (first as a volunteer, then as a paid intern), don began his legal career as a staff attorney for Land of Lincoln Legal Assistance, until he became the managing attorney of the Springfield field office where he served for seven years. In 1994, he opened his law firm, and in 1998, he joined Gregory P. Sgro in his practice first established in 1987.

He concentrates his practice in the area of Social Security disability claims and appeals. Unlike many attorneys who practice in this area of law, Don represents clients at all levels of the process, including the federal courts.

Don is AV Preeminent Rated by Martindale-Hubbell, an achievement ranking him at the highest level of level of professional and ethical excellence, and is also recognized as a Leading Lawyer by the Leading Lawyers network. He is a sustaining member of the National Organization of Social Security Claimants’ Representatives, a member and past director of the Sangamon County Bar Association, and a member of the Illinois State Bar Association.

After 40 years of practicing law, Don has decided to enter semi-retirement as of July 2022. While he will still accept select disability claims and appeals for full representation, the number of cases he accepts will be significantly reduced. Still, he expects to accept and return calls and correspondence to those seeking assistance, and for those whose claims he is not able to accept, appropriate referrals can be made.
