For seven years, Sharon Koehler has served in the position. However, she turned in her resignation effective Monday.
Koehler cited time as a reason for leaving the post.
"I want to spend more time with (my parents)," Koehler told The Brazil Times.
Koehler has been active with the club for approximately 20 years.
She said the club now has 30 days to conduct a caucus and fill the position.
"I have talked with (interested people)," she said, regarding the position of party chair.
Koehler added she will miss working with many individuals in the party.
"I really have enjoyed making so many new friends," she said. "I intend to stay involved. I'll still volunteer, and I'll still be a member. I'll still be active."
Republican Club Vice Chairperson Paul Sinders said Koehler has played a vital role for the organization.
"I think Sharon has been a very dedicated individual," Sinders said. "She's very organized and very loyal. I think she's worked hard for the people of Clay County. In my opinion, she's going to be greatly missed by all of us."
Sinders said Koehler informed him of her decision only recently.
"She said she felt like it was time for her to give this up and to get a new face in there," he said.
Sinders added letters will be sent out to Clay County precinct individuals and someone will be caucused in before the end of the month.
