The Mayor of Wilmer, Sheila Petta, decided to step down effective immediately. Petta submitted her resignation letter Friday morning, calling serving the residents of Wilmer “one of the greatest honors” of her life. Her resignation letter read, “It is with mixed emotions that I submit my resignation as Mayor of the City of Wilmer, effective July 10, 2026. Serving the residents of Wilmer has been one of the greatest honors of my life.” Petta worked within the city for more than a decade, first being elected mayor in 2020. She had just been reelected for another two years in May. In the past she also served on the Planning Zonning Commissioner followed by two terms on the city council. She did not give a reason for her resignation. During her time as mayor, Petta took the honor of being the city’s first elected official to earn a certified municipal official designation through the Texas Municipal League. She also represented Wilmer on the Texas Municipal League Small Cities Advisory Council, The North Texas Mayors Economic Council, and the Best Southwest Partnership Board. Wilmer City Administrator Frank Posada said, “I worked with Mayor Petta for a short time before her resignation; however, I appreciate the work and dedication she has put into the City of Wilmer.” ...read more read less
