Gayle enjoys all areas of dentistry, but her favorite is still the braces.

Gayle is our own personal jack-of-all-trades.  Besides all of her hard work in the dental end of things, she does much more.  Whether we have a glitch on a computer, a chair stops working, or the x-ray machine just won't budge, we know if we call her, she will get the job done.  We appreciate her can-do attitude and her willingness to do whatever it takes to keep this operation running smoothly!
