Jeremy Kooi is originally from Muskegon, MI and currently lives in Mineral Point, WI. He is the proud father of a son (Mason) and a daughter (Avery). A self-proclaimed “insurance geek,” Jeremy enjoys helping people navigate their way through the
complexities of their policies and is constantly educating himself on what’s new in the industry.
Jeremy has been an insurance agent for 17 years and spent the first half of his career focused on training and team-building, throughout the state of Wisconsin, for the leading voluntary benefits carrier in the US. In 2015, he moved on to become a full-
time employee benefits broker in Southwest, WI focusing on strategic plan designs and employee education. “Families spend a large part of their budget on health insurance and I’m committed to helping them understand their plan options.”
“At the end of 2016, I knew I was ready to change my focus to P&C.” Since joining Wallace, Cooper & Elliott in July of 2018, Jeremy has focused on partnering with businesses to help them with their commercial insurance needs. “When I was in
college, I knew I wanted to work in business but never would’ve imagined it would be in insurance. Working with business owners and having strategic conversations about growing their business is why I do what I do. It’s a great feeling to know that I can help others while protecting their dream.”
During his insurance career, Jeremy has been mentored by some of the most knowledgeable, ethical, and customer-focused people in the industry. Jeremy has a clear vision for the future of the insurance industry and is excited to be part of Wallace, Cooper & Elliott to make that vision a reality.
In his spare time, Jeremy serves on the Richland Hospital Foundation Board, enjoys golfing along with spending time outdoors camping, hunting and fishing with his family.
Sheila (Strang) Troxel is a lifelong resident of Richland County where she grew up on a dairy farm near Sabin, WI with her 7 siblings and parents. After graduating in 1978 she had the wonderful opportunity of being hired by Warren Wallace, Willis Cooper, and Bob Elliott and began her career with Wallace, Cooper & Elliott Insurance Agency. Sheila is a licensed agent in property, casualty, life, and health. In 1989 Sheila, along with her business partner, Mike Edwardson, purchased the agency and ran it together until Mike’s retirement in May of 2010 due to health complications and sadly lost his battle with Agent Orange which he contracted while serving his country in Vietnam. Sheila became the sole owner of the agency at that time. After 50 plus years at the same location Sheila and her staff decided to move their offices to the busy corner of 197 S. Main Street in downtown Richland Center where they are currently located.
Sheila has two sons, Andy, who is a high school history teacher and head football and track coach at Richland Center High School. He and his wife, Jillian, have two children Rosalynn and Liam. Aaron has been involved in several successful business startups both in the area and outside of Wisconsin. He has three children, Alayna, Sadie, and Graham.

She has served on many different boards in the past including The RCHS Booster Club, The Richland Hospital Foundation, The Richland County Performing Arts Council, The Blue Ribbon Committee and currently serves as a board member for The Woodman Foundation and The Richland School District.
In 2022 Sheila made the decision to change her role at the agency. She sold the agency to her valuable and trusted employee, Jeremy Kooi, who had worked for her for several years and she has gone back into sales where she began almost 45 years ago. This allowed her to have a different schedule so she could spend more time with her family and working on her air bnbs.
Sheila loves being able to give back to the community that has been so good to her and her family for so many years. She is very proud to call Richland Center home.
