Dr. Yen Duong Bergquist


Dr. Yen Duong Bergquist was born and raised in Houston, TX. She holds a BS in Nutrition from the University of Houston and a BS in Vision Science from Nova Southeastern University in Ft. Lauderdale, FL. She earned her Doctorate of Optometry from Nova Southeastern University in 2009. During her time there, she did extensive clinical rotations in ocular disease, contact lenses, pediatrics, vision therapy, and low vision.

Dr. Bergquist moved to the Pacific Northwest in 2010 and has since worked in many different modalities of practice. She joined Kosnoski Eye Care in 2019 after taking a few years off to pursue a degree in Apparel Design and Development from Seattle Central College. She currently teaches fitness classes (barre, HIIT, stretch, boot camp, and TRX) in her spare time. She also enjoys staying active and traveling with her husband and daughter.

During this time of uncertainty, the Kosnoski Eye Care family hopes that you are staying safe and healthy. In compliance with Washington state's Stay Home, Stay Healthy order, we will be temporarily closing all of our offices for a minimum of 2 weeks.

During this time, we will be answering your calls and Dr. Kosnoski will be seeing patients with eye care emergencies. Please call us if you are experiencing an eye care emergency at (253) 852-2020.
