In fall 2015, Tiffany Sizemore-Thompson joined Duquesne Law as an assistant professor of clinical legal skills to launch the Juvenile Defender Clinic and plan an Education Law Clinic, which will open in fall 2016. She currently supervises the Juvenile Defender Clinic and the Unemployment Compensation Clinic.

She came to Duquesne after serving for more than two years as the deputy director for the Juvenile Division at the Office of the Public Defender (OPD) in Allegheny County. As deputy director, Sizemore-Thompson managed 11 full-time juvenile defense practitioners who appeared before approximately a dozen family court judges. Sizemore-Thompson was responsible for the development and training of those lawyers in all aspects of the practice. During her time at OPD, she also did significant policy work with a variety of stakeholders in the delinquency system in order to ensure the best possible outcomes for the children it serves. She also wrote and implemented new practice standards across the Juvenile Division. 

Sizemore-Thompson is frequently asked by media sources to comment on juvenile cases.

Sizemore-Thompson was appointed to the Juvenile Court Procedural Rules Committee in 2014.  She joined the board of directors for the Juvenile Defenders Association of Pennsylvania in 2013, and in 2014, the board of Youth Enrichment Services, a mentorship and youth development program based in Pittsburgh. 

Prior to her work in Allegheny County, Sizemore-Thompson was a trial attorney for eight years at the Public Defender Service (PDS) for the District of Columbia, which is widely regarded as the premier public defender organization in the country. While at PDS, she represented clients in cases from presentment through disposition of the case, and handled serious violent felonies, including homicide, sexual assault, armed robbery, armed kidnapping, and armed carjacking. Sizemore-Thompson spent approximately two years almost exclusively handling juvenile cases at PDS. As a litigator, her work has also included representing witnesses to crimes, targets of grand jury investigations, and defendants in diversionary courts, e.g., mental health court or drug court. 

Sizemore-Thompson has conducted various trainings over her time as a public defender, including on the following topics: fundamentals of the rules of evidence, effective juvenile disposition advocacy, how to prepare for an interview as a public defender, and fundamental trial skills training (i.e., opening statements, cross-examinations, closing arguments, and development of defense theme and theory). 

Sizemore-Thompson graduated from Howard University School of Law, cum laude, in May 2004. For her undergraduate studies, she attended Antioch College in Yellow Springs, Ohio where she received her bachelor’s degree in education. She is a native of Pittsburgh and an avid Steelers fan.
