For over 30 years, Demetrio has been an elected Fellow of:  The International Academy of Trial Lawyers (top 500 in the U.S.), American College of Trial Lawyers (top 1% in the U.S.), and the Inner Circle of Advocates (top 100 in the U.S.). 

A leader of the bar, Demetrio has served as President of the Illinois Trial Lawyers Association and the 22,000-member Chicago Bar Association.  He is an internationally sought after lecturer on trial techniques and advocacy skills and has authored more than 60 professional articles.

Demetrio served on the Board of Advisors of IIT-Chicago Kent College of Law from 1992-2024, which included serving as its long-time Chairman.  He has been President of its Alumni Association and has been honored by being named as one of its 125 Alumni of Distinction.  He is a recipient of its Alumni Merit Award, Professional Achievement Award, and Distinguished Service Award

Demetrio currently serves on the boards of the Center for Disability & Elder Law and Big Shoulders-Archdiocese of Chicago.  He has previously served on the boards of:  Illinois Institute of Technology; St. Ignatius College Prep; Mundelein Seminar; Notre Dame Law School; Dispute Resolution Research Center of the Kellogg Graduate School of Management, Northwestern University; and the Constitutional Rights Foundation Center.

While Demetrio served as president of the Chicago Bar Association, he wanted to impact the lives of Chicago’s underprivileged children who, he sensed, would greatly benefit from quality mentoring. The Thomas A. Demetrio Award of Excellence was thus created recognizing the efforts of exceptional tutor/mentoring programs in Chicago communities.  In 1995, with Demetrio’s inspiration, guidance, and support, the CBA and Chicago Bar Foundation created the Lawyers Lend-A-Hand to Youth program, which continues to thrive today.  In addition to the annual Demetrio Award, it has granted over $1.6 million to mentoring programs for underprivileged youth in the Chicago Area.
