DPS Leadership

Tom Boasberg, Superintendent

tom-boasbergSince being unanimously appointed as superintendent of Denver Public Schools in January 2009, Tom Boasberg has led the city’s efforts to accelerate the progress of its nearly 92,000 students and better serve the families of Denver. Over the past eight years, the district has posted record enrollment increases and increased its four-year graduation rate by over 25 percentage points.

In the past decade, DPS has moved from being the district with the lowest rate of student academic growth among major Colorado districts to the district with the highest rate of student academic growth. The district has also more than tripled the number of its students taking and receiving college credit for Advanced Placement courses. And, it has cut its drop-out rate by more than 60 percent.

DPS has received national recognition during this time for exceptional leadership development programs for teachers, school leaders and principal supervisors; school choice; collaboration among district-run and charter schools; and promising new schools. The city has welcomed more than 75 new schools and the closure or turnaround of more than 30 chronically under-performing schools.

Before DPS, Tom worked as vice president for corporate development at Level 3 Communications;  served as legal advisor to the Federal Communications Commission, where he helped establish the  E-Rate program, which provides over $2 billion a year to high-poverty schools across the country to pay for telecom and Internet services; and was chief of staff to Lee Chu-Ming, chairman of Hong Kong’s largest political party, working on issues related to Hong Kong’s change of sovereignty in 1997.

A speaker of Cantonese and Mandarin Chinese, he worked as a junior high school English teacher in Hong Kong’s public schools and played semi-professional basketball. He earned his bachelor’s degree Summa Cum Laude in history from Yale College and a J.D. with Distinction from Stanford Law School. At Yale, he was selected as a Harry S. Truman Scholar.

While she was the principal, Remington experienced a gain of over 33 percent over four years on the state reading assessment. In 2002, she was recruited to the district level to broaden her impact.
