A mother of 5 with 3 grandchildren, Mandy began writing service in 1994 for her dad at a small independent shop in Moorcroft, WY called Williams Auto Repair. Since that time she has also written service for Thunder Basin Ford in Gillette, WY and Spradley Barr Ford in Fort Collins, CO before coming to Platinum Garage in 2017.

Spending time with her family is at the top of what Mandy likes to do in her free time. When not with them, she can often be found on the banks of the Powder River with her fishing line in the water hoping to catch a record-breaking catfish or sturgeon. She also enjoys spending time in her garden, tending to her animals, and working in her yard.

When it comes to customer service, Mandy says “Communication and honesty are the two most important factors in providing superior customer service.”
