Key Construction Inc. has promoted one of its own to chief financial officer.<br /><br />President Dave Wells tells me that he has promoted Carrie Lindholm from her role as Key’s controller to CFO.<br /><br />Lindholm  came to Key eight years ago after spending two years as an accountant with the Hayes Co.<br /><br />Wells wasted little time in filling the vacancy left by last month’s departure of John Walker, who  became president at Physicians Development Group after 15 years at Key.<br /><br />Lindholm, meanwhile, is a member of the Wichita Business Journal’s  2008 class of 40 Under 40. She has a bachelor’s degree in business administration with an emphasis in accounting from Wichita State University and a bachelor’s from Kansas State University in human resources management.<br /><br />Lindholm will lead Key’s six-person accounting team.<br /><br />“If you have qualified people, it’s always nice to promote from within,” Wells says.
