Bill SiebertBill Siebert - - (Direct: 636-343-1000 ext 235)

I have been in the industry for over 30 years with experience at all levels of the company. I currently am on the regional board for Safeco Insurance, but have served on many carrier councils as an advocate for the consumer and local agents. I've also teamed with Lindbergh High School and Fox via their Business Office Experience Program teaching students about insurance & finance with several continuing on in the industry. My hobbies are riding motorcycles, water skiing, traveling, and I love Corvettes and classic cars.
Karen SiebertKaren Siebert - - (Direct: 636-343-1000 ext 234)

I have been in the insurance industry for 22+ years - prior to that I was a teacher and trainer for Special School District. My love of children remains, so often our agency fundraisers are related to helping kids in need including Shriners Children's Hospital and Special Olympics. I attended Westminster College in Fulton, and taught the gifted at the Churchill Academy prior to entering the business field. I'm blessed to have such a great team that wants to help others not only in our service related industry, but the community

Army Veteran 1972-1974, over 40 years of experience as a licensed broker, married with four children and eight grandchildren. Primary hobby is traveling around the country to visit said grandchildren. I love my work as I am able to meet with and help a broad range of people. It is a special pleasure getting to know my long term clients on a more personal level over the years as their families grow and evolve.

I've been in the insurance industry & with Siebert Agency since 2011. I have a degree in business management and graphic design.

Passion for motorcycles, guitars, old cars, and people led me to what I do now. But still on my off time you can find me on two wheels, doing some sort of shooting sports, being an avid conservationist, and in other words just being outside in the elements. And on those terrible days you can find me at my place playing the guitar, (free of charge)
