Colette Troeller

Vice President

As a child growing up, Colette had been around the business at Edward H. Wolf & Sons. When she was young, she remembers her parents working long hours at the kitchen table.

With her parents impending retirement, she came back to the business to help to manage important pieces for the last 18 years.  

When her parents retired, Craig (her brother) and Colette purchased the business. Today, Colette is Vice President of Edward H. Wolf & Sons and is heavily involved in the fuel division.  

In her spare time, Colette spends her time with her husband and two children and is a strong supporter of her church and community.
