The Center for Advanced Orthopedics’ goal is to always provide you with the highest quality of care. Our highly trained staff is focused on your care as an individual with an emphasis on a personal touch.¬†You don’t have to drive to St. Louis to see top orthopedic physicians and staff-we’re located right here in the Metro East. We have three convenient locations in Maryville, Staunton and Highland, IL.

Conservative treatment options including immobilization, therapy, and selective injections are always utilized prior to considering surgical intervention. When surgery is necessary, specialty training by our physicians ensures that your procedure will be performed with the most up-to-date techniques and treatment. If you do request or require surgery, we will take the time to answer all of your questions and will provide you with information on the type of procedure, any potential risks, and the post-surgical rehabilitation process.

I had ankle fusion surgery in June 2016 and while it is still healing, it is so much better. Thank you, Dr. Grebing. I am definitely thinking about switching all of my Orthopedic care to CAO and Doctor Grebing.

  Dr. B did both my hands for carpal tunnel in 2014. He and the staff made it all feel really easy and relaxed, while still taking any questions and concerns I had very seriously. Would definitely recommend C4AO!
