In a letter to the chamber and BEDC boards, Stillman stated, "I am satisfied knowing I was able to play a role in laying the foundation for a promising future in this wonderful community."
Ted Riley, president of the chamber board, said Stillman did an "excellent" job in serving the chamber and community.
Riley stated in a press release, "Stillman has been an important part of Brawley's chamber activities, economic development planning and an active and effective community leader."
He credited Stillman for her ability to bring new businesses to the city.
Riley pointed out Stillman recently received a state trade and commerce enterprise zone excellence award for her efforts in developing a marketing package highlighting the city's manufacturing enhancement zone designation.
Stillman was credited for helping develop the Brawley chamber Web site and e-commerce services for chamber members.
Riley said it is too early to say what will be done to bring in new leadership for the chamber and BEDC. He said there will be a meeting next week to decide how to move forward.
Riley said he is unsure if there will be changes in the way the chamber and BEDC operate or whether there will be one executive officer hired for both agencies.
Stillman said she accomplished most of her goals in the job. Still, she said there are projects she would have liked to have finished.
One project she has been involved in is trying to obtain a California Main Street designation from the state, which would allow the city to tap into resources for the upgrade of the city's downtown.
Stillman said processes are in place that could "make the economic outlook for the city a bright one."
