CTA Inc.

HR Generalist

I grew up in Billings and later attended Washington State University. After college I did the staffing for the National Bowling Tournament and lived in 7 different cities in 7 years. The last 4 years I have been working in HR for Whole Foods Market, with the last 2 being in Breckinridge, CO.

I am happy to be back in Billings and spending time with my sisters and brothers and 6 nieces and nephews.
