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 offices in Virginia, Washington D.C. and Maryland.
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. Our ability to compare all Part D drug plans can save hundreds if not thousands of dollars a year for our clients.
Steinlage offers its clients a singular direct connection to the various insurance companies, making life easier and uncomplicated.
