I've been going to Dr. O for about 2 years now and I don't see myself changing dentist.
His staff is very accommodating and such an excellent team. They really pull the office together.
Dr. O himself is such an amazing dentist. I find myself in the waiting room for about 2 minutes before being called back. Him and his staff are very efficient with your time and will get you in and out as soon as they can.
If you're in the Henderson area (or not) and are looking for a dentist. Dr. O is your man!
