Alumnus Spotlight: Mike Kelleher, M.D. (Class of 1975)

A Friar student-athlete turned pediatrician reflects on the ‘formative influence’ of Fenwick’s teachers and coaches.

By Mark Vruno

In the fall ’21 Friar Reporter (page 16), we reported that alumnus Dr. Tord Alden ’85 was hired into informatics at Ann & Robert H. Lurie Children’s Hospital (Chicago) by fellow Fenwick Friar Dr. Michael Kelleher ’75, a pediatrician who spent 17 years at Lurie (Children’s Memorial).

In 2020, Dr. Kelleher became the chief medical officer of Amita Health (Mercy Medical Center, Aurora, IL). For 11 months he chaired the COVID-19 Vaccine Steering Committee, which administered more than 50,000 doses to area health-care workers, first responders and patients.

“I had Roger Finnell for four years,” remembers Dr. Kelleher. “Roger [Fenwick Class of ’59] was a young man when I was at Fenwick. He is a wonderful math teacher and a great human being! I still remember what ‘e to the pi I’ equals.” [Euler’s formula: e^(i pi) = -1]

Kelleher also ran track and cross country for Coach John Polka for four years. “Mr. Polka was my biology teacher, too. These two men had a formative influence over me,” he notes, adding that, in the early 1970s, he was taking “regular and honors classes, which they now call AP [advanced placement], I think.”

Sneezing into med school

Graduating in three years from Northwestern University (Evanston) with a B.A. in biology, Kelleher went on to the University of Minnesota to earn a master’s degree in ecology. His study emphasis was on population genetics and statistics, but severe allergic reactions forced him to change his mind. “I had terrible allergies and couldn’t do the field work,” the doctor recalls.

Kelleher had thought about pursuing medicine in the past, and he received his M.D. in 1986 from the University of Illinois College of Medicine (Urbana and Rockford, IL). His post-graduate training took place at Wyler Children’s Hospital at the University of Chicago, where he competed a residency, became chief resident and was a Pediatric Critical Care Fellow (1990-93). He also served for five years on U of C’s faculty.

Before coming home to Chicago, Dr. Kelleher spent five years in Iowa City as the head of Pediatric Critical Care Medicine at University of Iowa Hospitals and Clinics. Once at Lurie (Children’s Memorial), he progressed up the ranks, first handling electronic medical record implementation and ascending to chief medical officer from 2003-19.

“My values were formed at Fenwick High School,” Dr. Kelleher insists, citing the service ‘mission’ of Catholic education as being integral to his experience. “There, our teachers inculcated us to provide service to others. They said that it should be a goal in life.” It’s no coincidence, he says, that several of his ’75 Friar classmates also went into the medical field.
