Here's something worth knowing if you're researching a move to the Kissimmee area or anywhere in Osceola County: your future hospital isn't just good — it's nationally recognized. AdventHealth Kissimmee has been stacking up awards from Healthgrades year after year, consistently landing on lists most hospitals never crack, like America's 50 Best Hospitals.
For anyone relocating to Central Florida, healthcare is one of those practical factors that often gets overshadowed by schools, commutes, and neighborhood vibes. But access to excellent medical care matters just as much — and in Osceola County, residents are fortunate to have a genuinely elite option right in their backyard. Let's dig into what makes AdventHealth Kissimmee worth knowing about.
From Kissimmee Memorial Hospital to National Recognition
AdventHealth Kissimmee traces its roots to 1941, when the Kissimmee Hospital and Clinic was founded at the home of physician Raymond Sessions. It evolved into Kissimmee Memorial Hospital before Florida Hospital (now AdventHealth) acquired it in 1993. A $7 million ER expansion completed in 2014 nearly tripled emergency square footage to over 22,000 square feet, and a $60 million patient tower added 80 private rooms in 2015. Today it's one of Osceola County's largest employers, with approximately 3,565 employees.
The Awards: What the Rankings Actually Mean
It's easy to see "award-winning hospital" and tune it out — but the Healthgrades recognition AdventHealth Kissimmee has earned carries real weight. Healthgrades evaluates hospitals using objective clinical outcome data, not surveys or marketing materials. Here's what the hospital has been recognized for:
