Kane County Treasurer David Rickert conceded the race for Kane County Board chairman to Corinne Pierog Friday.

“Although not mathematically eliminated, it’s time to call this race. Congratulations to Ms. Pierog, the next county chairman,” Rickert said in a prepared statement. “Once, again thank you to all of those who helped and encouraged me. It’s time for me to roll up my sleeves and continue to serve as Kane County’s Treasurer. Also, I plan to spend a lot of quality time with my friends and family.”
