Who We Are:

Founded by William H. Steinlage Sr. and family-owned and operated since 1950, we are proud of our almost 70 years as a respected and dependable Medicare health insurance agency. There have been many changes in the insurance and healthcare industry—miraculous advances in medicine, longer life spans, skyrocketing healthcare costs, and the birth of a national healthcare program. Our agents and their customers know they can rely on us to continue to grow and adapt to meet their needs, whatever may come next.

At Steinlage, we dedicate ourselves to earning the title “THE BEST MEDICARE HEALTH INSURANCE AGENCY” each and every day. We are a nationally recognized, award-winning leader in the Medicare insurance brokerage industry. We are headquartered in St. Louis, Missouri with multiple offices in Virginia. 

Our primary focus at Steinlage is our nation’s seniors. As a Medicare-focused company, we are a trusted source in the industry for Medicare knowledge, trends and news. In addition, the partnership Steinlage maintains with just about every top-level insurance carrier allows us to provide Medicare recipients complete access to the highest quality and competitive products.

There is no other Medicare health insurance agency in the nation that supports its clients like Steinlage. Our complete back office support system is unparalleled and uncompromising, built on close relationships that have grown through the years. Our advanced technology allows us to be flexible and respond quickly as needed, and our friendly staff is energetic, and their get-it-done attitude makes doing business easy and efficient.

When not working, she stays busy with her husband from the home of Mt. Everest, Nepal & their 2 children; Ezekiel – 7, Naomi Grace 4. Her family loves to get out & about going to see new things, participate in every activity they can find. Summertime finds them at the pool often. They love cuddling up on the couch together as a family watching movies, playing board games & simply being in one another’s presence (though they sometimes drive her bonkers, they are her life!). She is very active in her church & when there is free time, she is part of a MOPS/Mom’s next Group that allows her to hang out with other mothers gleaning insight, sharing child-raising stories & just getting a break. She is a huge Cardinal Baseball Fan (#51 Willie McGee will always be in her heart’s Hall of Fame). She loves music of nearly every kind & enjoys singing. She spent many years volunteering at Lindenwood University helping & loving on International Students from all over the globe. She appreciates her time with those from other cultures be it visiting, dining, or learning more about life as they know it.

Her time here at Steinlage thus far has opened her eyes to the craziness of this industry. She can understand why it would be difficult to navigate Medicare on one’s own. Day in & day out, she has the opportunity to watch the brokers work their magic & do so with compassion, knowledge & honesty. As her parents prepare to delve into the Medicare World, it brings great peace knowing that the Steinlage Team will be watching out for them. She looks forward to being here at Steinlage for many years.
