Assistant Longview Location
My journey helping animals spans over 30 years. For the past two and half years that passion has expanded to include veterinary dentistry and oral surgery. I love getting to know my patients, earn their trust, and build relationships with their human family members.

In my free time you’ll find me in the great outdoors, exploring new waterways on my paddleboard, hiking trails, camping, fly fishing, and enjoying everything that the pacific northwest has to offer. When I’m not out on my adventures, I love to spend time at home with my loving husband and amazing daughter.

My four-legged family members include Sandy (spoiled chihuahua), Furgus (my chubby cat) and my adventurous corgi named Bear!
