Ms. Klopfenstein moved from Illinois to Colorado to beautiful Sheridan, Wyoming in 2007.  She has always been actively involved in local government / politics starting in IL where her grandfather was mayor of their town, her father served as village trustee, and she spent 24 years elected to the Library Board as well as County Board member for one year before moving to Colorado.  She currently serves as Precinct Committeewoman and State Central Committeewoman for Sheridan County, and is the past-president of the Republican Women of Sheridan County.

Ms. Klopfenstein is retired from pharmaceutical sales and currently works as a merchandiser in local stores.



My family and I visited Sheridan in the summer of 2021 and decided to make Sheridan our forever home. We wanted to provide a better quality of life for our son, embrace Wyoming values, and live out our days beside the Big Horn Mountains. My wife, Shelley, and I have been married for over eighteen years. We have three adult children, one child at home, and four grandchildren.

I have always been an entrepreneur, and retired in 2015 from selling insurance as the CEO providing life, health, and financial services. I enjoy spending time with my family, camping, hiking, hunting, amateur radio, and tinkering with electronics and cars. I love to explore new places in and around Wyoming, meet new people, help out when I can, and be involved in our community.

I have served on numerous boards including a Home Owners Association, Amateur Radio clubs, Science Technology Engineering and Math program, Search and Rescue team, and Parent Teacher Association. I served in many capacities on those boards as chair, vice chair, treasurer, and master at arms, to name a few. I have found all of these roles to be fulfilling in different ways, none more important than the lasting relationships I have made over the years.

I ran for Precinct 4-3 Committeeman in 2022, and won my seat. In December that year we bought a home in a different precinct and I had to resign my seat. In March 2023, I ran for the Sheridan County Republican party treasurer and was elected by unanimous vote. I attend Sheridan County School District #2 school board meetings and Sheridan City Council meetings regularly, and Sheridan County Commissioner meetings when I am able to. It is important to me to be informed about what is happening in my community.

I strive hard to work with others to hold elected officials and those in positions of power accountable. I am a strong advocate for Constitutional and Parental Rights seeking to make things better for my children, grandchildren, and future generations.

I look forward to continuing to do my part in keeping Sheridan a beautiful community to live in. I thank you for allowing me to be of service.
