ELLEN SPANGLER, SENIOR PROJECT MANAGER AT MORTENSON CONSTRUCTION
Bio: Ellen earned a degree in architectural engineering with a focus on construction management from the University of Colorado - Boulder. After graduation, she was hired as a field engineer at Mortenson Construction.
Ellen, who has worked at Mortenson for nine years, is a senior project manager currently leading construction of the St. Louis City SC Major League Soccer (MLS) Stadium. Ellen has worked on three major sports projects leading up to St. Louis MLS including U.S. Bank Stadium in Minneapolis, Minnesota, where she worked with the team handling heating, cooling and life safety systems; Milwaukee, Wisconsin’s Fiserv Forum, where she was a key player in the structural steel phase and the scoreboard installation; and Allegiant Stadium, home to the Las Vegas Raiders, where she was the Enclosure Team leader.
On the Allegiant Stadium project, she led the team to a successful execution of a difficult glazing, metal panel and roofing scope. Ellen also led the formidable closeout effort, working through punch list completion and substantial completion requirements, helping the team achieve an early and under-budget turnover of a landmark project in the midst of a global pandemic. With each successive project, she continually tackles the challenges head on and aims to apply each gained experience to the next project.
Ellen loves construction due to its complexity and especially enjoys working on sports projects because they are high-profile projects that generate community excitement. Her ability to pivot and take on any new challenge thrown her way has been a huge asset to each project team she is a part of.
