Purdue University Northwest (PNW) has selected three impactful alumni to honor as its second annual PNW Alumni Hall of Fame class.

PNW’s 2023 honorees include Robert Johnson III, Stewart “Stu” McMillan and Alfredo “Al” Sori.

“These distinguished honorees embody the qualities of PNW alumni: people who built upon their PNW degrees to provide transformational change for the region and the world and who continue to devote attention to the university so that others may be inspired to pursue their own dreams,” Purdue Northwest Chancellor Thomas L. Keon said.

“Each of our 2023 honorees have been innovators and leaders in their industries. They have also remained loyally connected to their alma mater by mentoring and supporting our students.”

PNW’s Alumni Hall of Fame honors alumni who are high-achieving leaders in their fields, involved members of their communities and who have engaged with PNW well beyond their time as students. This year’s three inductees will be honored June 8 during a reception and dinner hosted in Alumni Hall in the Student Union and Library Building on PNW’s Hammond campus.
