Diane Siegrist – Office Manager

After several jobs in high school Diane began employment with Craig Hospital in 1976 as a switch-board operator. She was quickly promoted into the office doing bookkeeping and accounting. She took several years off to raise her two children Danielle and Robert. During those early years however, she was still involved in the family business writing the company newsletter, organizing company functions and managing the co-ed Contractors Softball League. She was always on call to fill in at the office when highway construction was in full swing. When Siegrist Construction was reorganized she took on all the office management responsibilities including payroll, accounts payable and accounts receivables. She currently does the bookkeeping and accounting for Siegrist Companies.

With her husband Mike, she has been very involved in children’s and youth ministry. For years she was a part of weekly youth group meetings, taking large groups of teenagers to conferences and summer camp. During that time she also was on the church board. She has since retired from the organized ministry but is still active in what are now, all those young adult lives.

In 2012, with her business partner Heather, she purchased a small salon. Under their leadership they have seen their revenue increase year over year. They moved into a 4000 sq ft, new building in 2019.

When Diane is not busy with her five grandchildren, or working, she enjoys traveling, a little golf or spending time in the mountains.
