I had the best experience at Diem Do!!! Everyone from the receptionist, Megan, Dr. Tammy, and the entire staff were amazing!!! They made me feel comfortable, respected, and most of all, not ashamed of my dental health!!! They were very understanding, they actually listened to me and my concerns! I felt like family, they even asked me about my son! They are equipped with the latest technology and equipment! They are very knowledgeable and thoroughly explained everything!!! I love the dental plan as well, it breaks everything down and shows you what it’s going to cost! I’m highly impressed with this dental practice and I’m so thankful I chose them!

As always, a pleasant trip to Smile in Style. Let's be honest, no one looks forward to going to see the dentist. However, drone his staff make it a very pleasant and comfortable experience. They are also all very knowledgeable and experience. It's worth the drive from uptown to go see them.
