I have worked for Mandeville Agency since 1982.  My time at Mandeville is spent working commercial insurance, keeping up with Tom in assisting him with his accounts & keeping the office running smoothly as the office manager.  I grew up in Absarokee & in 2001 moved to Columbus.  My heart belongs to my two daughters and three grandchildren who I adore.  After work and on the weekends, you’ll find me doing my favorite past-time gardening & landscaping.   I also enjoy traveling and attending my grandchildren’s many activities!

I began my insurance career with Mandeville Agency in 1975. I am a Certified Insurance Counselor and a licensed insurance consultant. I am now officially the old guy who sits in the back office. I specialize in life and health insurance and would be happy to visit with you about Medicare supplement insurance, long term care insurance and health and life insurance. I am a native of Columbus and am convinced that there is no better place to live and raise a family than Stillwater County. My wife, June, and I have two grown sons and five grandchildren.

 A true outdoor enthusiast, hailing from Billings, I find peace and serenity in our great outdoors. My husband and I share the same joys of camping, hunting, fishing and mostly anything that allows us to relish the beauty that nature provides. Insurance is nothing new to me. I bring years of experience working with home and auto insurance.

Although a Columbus native, I started working in the insurance business in 1983 in Anchorage, Alaska. We moved back to Montana in 1993 and I started working at Mandeville Insurance Agency in 1996. I work primarily with personal insurance, writing home and automobile insurance. I also work as Webb's assistant helping with his farm and ranch and commercial insurance accounts.

I lived in Absarokee for 11 years and graduated from Absarokee High School. I briefly lived in Billings until I met my husband Barry. We have been living in Columbus for the last 8 years and had our daughter Candace join us in 2014. We love to go camping, boating, and travelling in the summer and our lazy football Sunday’s in the winter.

I am new to insurance and enjoy working with the great team we have here at Mandeville Insurance Agency! I look forward to meeting our valued clients and people of our community!
