About Crown MedRealty
While working together in Kansas City, the founding partners took an interest in the burgeoning medical real estate market.
We established Block Healthcare Development in 2011 as a division of Block Real Estate Services to build expertise and a portfolio of medical properties.
As our healthcare deals stacked up across the country, we saw the potential to create long-term wealth and value for both physician groups and investors. We also enjoyed the problem solving and creative deal making that came along with structuring these healthcare real estate deals to the benefit of all.
After 10 years of making successful deals and building a stellar reputation with brokers, the four partners decided in 2021 to create an entirely new company – Crown MedRealty Partners – with a vision of becoming the premier medical real estate investment company in the U.S.
Though headquartered in the Midwest, we work on medical office deals across the country and have deep knowledge of the different real estate markets. Our team is made up of seasoned real estate professionals with decades of experience who focus exclusively on healthcare commercial real estate. We know the market. We know the players. And we know how to put together deals.
With deep roots in Kansas City, our new company holds tight to its Kansas City pride and Midwestern values. We keep our word and act with integrity. “Crown” is a nod to Kansas City’s winning professional sports teams, and the four stars above the W in our CROWN logo stand for each of our four founding partners.
We are flexible, fast, and take a hands-on approach to healthcare real estate investing. We act like a startup by reacting and adapting quickly and by staying lean, nimble, and hungry. We strive to give quick answers and quick turnaround – this is not working by committee. We make a decision and GO.
Finally, we are truly your partners in medical real estate investing – because we are investing in every deal right along with you. Every deal is a chance for us to stretch our creativity and we thrive on that. We’re highly motivated to make things work and to fix any problems that might come up. We’re in this for the long term, and we plan to make this venture a success!
