Kathy Green, RDH

Do you look forward to your six month dentist visit so much that you have it marked on your calendar with a smiley face?  If you answered yes to this question, it's a pretty good guess that Kathy is the dental hygienist for you.

Kathy grew up in Northern Wisconsin swimming in Lake Superior in the summers.  She moved to Washington in her early twenties.  She has three adult children and a sixteen year old son.  She enjoys a variety of adventures throughout the year including snow skiing, water sports such as kayaking, and water skiing.  She is a bicyclist and occasionally rides to and from work.  She likes spontaneous travel and is working on her bucket list.

Kathy has been a licensed dental hygienist in Washington State for seventeen years.  She has worked with Dr. Barton and his warm friendly staff for the past ten years.  Together we work to remove the common perception that going to the dentistry is "scary" or "painful."  She has excellent people and communication skills and enjoys interacting with her patients on a regular basis as we work together to prevent serious dental health issues and diseases.
