Corey Hastings, DDS, MS

I am passionate about dentistry for children and helping them reap the benefits of healthy teeth and a great-looking smile for life! If there’s one thing I hope to accomplish in my career, it’s helping all of my young patients learn to love visiting the dentist. There’s absolutely no reason a dental appointment should be intimidating. It’s my job to help children learn and understand the real benefits of excellent oral health!

After attending dental school at SIU and my certificate in Pediatric Dentistry from the Children’s Medical Center, I began my career in the industry with my own dental practice back in 1986. I have loved working with kids and helping them keep their smiles healthy ever since!
