Dr. Corey Hastings

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!

 Dr. Rob Hashemi

Dr. Rob may not originally be from the Lou, but he is excited to get to know all of his new (Cardinals loving) patients! Dr. Rob grew up in Massachusetts, but has lived in all kinds of exciting places, from the Big Apple to the Nation’s Capitol. In his free time, you will likely catch Dr. Rob riding across the country on his bicycle or playing fetch at the park with his dog pal, Charlie. He loves the great outdoors and enjoys traveling all over the world. He is also ready to be a huge fan of St. Louis City SC!

I completed my undergraduate degree at Wofford College where I earned my bachelors of science in biology, then went to UNC School of Dentistry for my DDS. I love providing dental care to children in a fun and comfortable environment. I am honored to have a job where I can put a child at ease and make them feel safe in a situation where they may be scared.

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 practice back in 1986. I have always loved working with kids and helping them keep their smiles healthy ever since!
