ST. CHARLES COUNTY — Francis Howell School District officials said Friday their new superintendent won’t start on Tuesday as planned. A deputy will assume his role on an interim basis instead.
“Due to unforeseen circumstances, Dr. Mike Dominguez is unfortunately unable to begin his duties as superintendent on July 1,†the district said in a message to constituents late Friday morning.
Francis Howell Board of Education appointed Deputy Superintendent Mark Delaney to lead the district in the meantime.
In a statement to the Post-Dispatch, district officials provided no further details, saying only the district is focused on a new strategic plan and will “continue to make progress†as it prepares for the upcoming school year.
The announcement came two days after the district’s board of education held a virtual closed session meeting to discuss personnel items on Wednesday.

Former Francis Howell School District superintendent Kenneth Roumpos speaks during a school board meeting in O’Fallon, Mo., on Thursday, March 21, 2024.
Roumpos said in December he was leaving Francis Howell for the top job at Kirkwood School District, where he starts on Tuesday. His announcement kicked off a hastened search for his replacement.
Superintendent searches can take several months or a year, but previous school board leadership said they sought to replace Roumpos quickly so his replacement could work alongside him.
Dominguez was hired on March 13, less than a month before a general election flipped a majority conservative elects held on Francis Howell’s school board.
