I went to Dr Leon on a recommendation from a coworker shortly after I moved to St Louis in 2002. Dr Leon had been my coworker's family dentist for around 20 years, and she recommended him highly. His office was easy to get to. His staff was very friendly and professional. His facility is spotless and very modern. I was reassured by his manner, and, while going to the dentist is never pleasant, Dr Leon made my visits as nice as possible. The only downside is that he's no longer covered by my insurance. I would recommend Dr Leon to anyone looking for a dentist in the area, especially if he accepts your dental plan.
