The Clear Choice

Dr. Smith is highly regarded in the field of dental sleep medicine and has trained dentists across the country in the treatment of obstructive sleep apnea. After a sleep study indicated I had severe apnea that needed to be addressed to safeguard my health, I researched which treatment options were best for me. Dr. Smith stood out as the clear choice. He was able to virtually eliminate my snoring. I've been a patient of his for 6 years. He's caring, attentive and very professional.

It really feels like being seen by friends.

I always feel like they care more about me as a person, instead of just as a patient! And the oral device I use has absolutely changed my life!!! I have more energy than I have in years and it's so simple to use. It's nice to know I can go on vacation with my family and simply slip my little case into my luggage and go.

Amazaing! Really a health issue demystified. This snoring disease is not what it's really all about. Without compliance to the appliance my heart will suffer when I sleep. The confidence I have received from Dr. Smith and his staff has improved my total health. My symptoms have all been resolved. It's the best choice to make for me.
