I am the mother of 3 active boys and have been married to my husband Ryan for 25 years.

I have had the honor of being a dental hygienist for almost 39 years, with the privilege of spending the past 19 years working for Dr. Dustin.  Although I now am a Vancouver resident, I was born and raised in Portland.  My husband Rick and I are the proud parents of one son, Ryan, and consider his wife, Heather, our “daughter”. I love running and training for half marathons, gardening, entertaining, traveling, and spending time with family and friends.  (My husband would also say I love to talk!)  I truly consider my patients part of my extended family, and love caring for their dental health while sharing our lives!




Krista – Dental Hygienist

I started with Dr Dustin in 2010 and have felt at home ever since! From having a less than desirable experience at the dentist as a child, I know I wanted to work in healthcare. I enjoy continually advancing my knowledge in the medical and dental fields. When I’m not at work, you can find me spending time with family, friends and my Chihuahua mix puppy, Tucker. I also enjoy hiking and discovering new music!





Shasta – Dental Assistant

I attended Riverside Community College and received my dental assistant certificate. I have been a dental assistant for 15 years and only worked with Dr. Dustin for 6 years. I have been married to my wonderful husband Matt. We have two beautiful daughters Katelyn and Maia, when I am not at soccer, I love to spend my time on walks and my winters snowboarding with my family and friends.





Jessica – Dental Assistant

I started my dental journey at Charter College in Vancouver Washington and graduated in 2013. I consider myself a “dental nerd” because I absolutely love everything about it. My favorite part about my job is when we get to help someone transform their smile. It’s rewarding to see how happy and confident it makes them! Besides dental, in my free time I enjoy hiking, camping, playing disc golf and playing with my puppy, Millie, who loves the outdoors as much as I do.




Betty – Schedule Coordinator

I have been lucky enough to work with a great team at Columbia River Dentistry for the past 2 1/2 years. Having studied nursing in college, the dental field was a whole new experience for me and I feel I’ve learned a lot! The best part of my job is interacting with and getting to know our patients. I enjoy hearing about their lives and I have gained some great new friends. Outside of the office, I’m a wife and mother to three beautiful and grown-up daughters. I enjoy reading, working out, and spending time with my family. I’m also a huge sports fan. Go Seahawks! Go Mariners!
