Gayle Surdey

Certified Dental Assistant
Certified Orthodontic Assistant
Hygiene Assistant

Gayle was born and raised in Spooner, and has always had River Street Dental as her dental home.  Her interest in teeth started when she had retainers and braces at this office as a child.  In 1990 she started working here as a Certified Dental, Orthodontic, and Hygiene Assistant.  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!

When Gayle is not here, you may find her riding around on a bicycle, paddleboat, or convertible with her husband, or taking one of her danger-prone vactions to a foreign country.  (We affectionately dub the tales that follow these adventures, "Gayle Stories").
