Happy Family in Nature


Our Doctors

Dr. Greg Knutson graduated from Kent-Meridian High School in 1982. From there he completed his undergraduate degree at Washington State University and subsequently worked for the Boeing Company for six years. He then went on to complete his dental training at the University of Washington, graduating in 1997. Afterward he bought the practice from his childhood dentist and has owned it for the past 20 years. Dr. Knutson enjoys family life on his farm with his pet goats, alpacas and chickens.

Dr. Greg Achtemichuk (aka Dr. A) was born and raised in Saskatchewan, Canada and moved to the States upon entering Ambassador College to earn his undergraduate degree which was followed with a Masters degree in Education from Cal State LA. He spent seven years as a teacher and vice-principal before attending the University of Washington School of Dentistry in the same class as Dr. Knutson. He spent one more year in UW's Hospital Dentistry Residency before joining us. Dr. A splits time between our office and another office in North Bend.

Our Hygenists

Brenda Swanson has been our rock solid hygiene superstar for over thirty years. She graduated at the top of her class from Pierce College. Brenda is as devoted to our patients as they are to her.

Danielle Gittings joined us as a hygienist a few years ago but initially began at Knutson Dental as a part-time assistant working her way through college. Her effervescent personality will make you look forward to getting your teeth cleaned!

Front Office

Shaunna Culp is our invaluable front office guru helping you with appointments, treatment planning and insurance claims. She began with us as a dental assistant ten years ago, worked her way up and keeps the office running smoothly, always with a smile.

Dental Assistants

Laura Brenneman is our newest dental assistant. Laura graduated from Renton Technical College in 2019 and has quickly become the doctor’s most valuable assistant.

Nat Kovalchuk and Jessica Zinchenko are our part-time assistants who do anything and everything that is asked to keep our office a well-oiled machine. Both are earning their college prerequisites in order to become dental hygienists.
