About Us

Osceola Medical Center has a rich history dating back to its founding in 1932. Throughout our growth, expansion, a new facility and the creation of this campus, OMC’s character has remained the same: to inspire and improve the health and well-being of our community through home-town customer service, quality health care and strategic partnerships.

Searching for health care that fits your needs? Consider Osceola Medical Center, where we strive to inspire and improve the health and well-being of our community through home-town customer service, quality health care and strategic partnerships.

We can say the same things many other medical centers say, that we combine technology, outstanding patient care and friendly service to provide you with the best care possible. Instead, we think our dedication to patients is best summoned up when our patients refer to us as “my OMC”.

What People Are Saying

Both the nurse and doctor were caring and effective in their care of me. They kept the mood light, but confident in dealing with medical condition. Excellent care.

An excellent facility, a wonderful Clinic, incredible staff and somewhere I will always go back to.

I was so pleased with how much time the Dr spent going over my medical history. So happy to have found this great Dr.!

Dr. Nguyen was amazing. He is so friendly. He answered all your questions. He is very professional. I ... first time we've ever seen him, so I would definitely recommend him as a provider. Our experience was nothing but great, the whole time.

Just a very friendly place with a great staff of people from the receptionist to the nurses and the doctor all very professional and very friendly great place!

Nicole did a great job on the well child visits. She really encouraged healthy lifestyle, and took time to talk to my daughter and get her feedback, and include her in care.
