“Margo helped make the transition to Medicare and supplemental insurance so easy. She simplified the process and in one meeting I had medical, prescription plan, dental and vision covered. I highly recommend her. Thank you, Margo.”Leslie W
“My husband and I met with Karl several times. It is comforting to be able to tap his expertise in the oh so confusing Medicare process. I read a lot of paperwork I was bombarded with and did some research on-line also. Having Karl’s direction gives me peace of mind. I would recommend him to anyone!”Karen D.
“Margo was very efficient and informed in helping us with our Medicare Advantage Insurance Plan. She helped us make the correct decision as well as doing all the paper work for us, much easier than going it alone. We would recommend the Steinlage Insurance Agency.”Bryce D.

Medicare Insurance Agency:
For three generations the Steinlage family has helped families with their insurance needs, specializing in the senior health market and Medicare insurance. The business started when a childhood friend of William H. Steinlage Sr. was drafted into WWII. He asked William to take over a “block of business.” Within a few years, William Sr. opened The Steinlage Insurance Agency. His number one priority was focusing on the needs of his clients.
In 1974, William was joined by his son, William H. Jr. Bill took the agency to new heights by meeting the demand that he saw in the senior health market, specifically Medicare related products. The agency became a leader by being one of the first truly independent agencies to focus on the Medicare eligible client.
During Bill’s tenure, the agency expanded to the greater Saint Louis area. As of 2001, the agency crossed the river from North County to Lake Saint Louis. In 2006, William Jr.’s two sons, Eric and Karl, joined him to assist in growing the family business. In 2009, Margo Bill’s daughter, also joined the agency as a broker and the agency’s senior health legal consultant. Margo, Karl, and Eric continue to advance the agency to new heights.
Today, this family dynamic at the agency enables Steinlage Insurance Agency to offer its clients reputable customer service and satisfaction. In addition to quality service, the agency is well informed on recent Healthcare Reform and relays this information to its clients. Loaded with experience and expertise, you can feel confident that Steinlage Insurance Agency will navigate and maneuver the health care maze for you now and into the future!
