Welcome to Klein Orthodontics!

Welcome to Klein Orthodontics! We are the longest, continuously operating family orthodontic practice in Oregon. Our office was opened by Dr. Paul Klein in 1954 and is now continued by his son, Dr. Douglas J. Klein, who joined the practice in 1983. Located in Lake Oswego and Tualatin, Oregon our priority has not changed since the practice was established years ago.

We strive to provide you the highest quality orthodontic care in a friendly, comfortable and ethical environment using traditional braces and Invisalign® clear aligners. We focus on what makes patients unique and then tailor our treatment recommendations to compliment each individual. We are aware that healthcare decisions can be confusing and overwhelming, especially in this day of modern social media and marketing. Our goal is to help you make an informed, candid, face-to-face decision regarding orthodontic care.

Please contact us if you have any questions or would like to schedule an appointment.


Invisalign is the clear way to straighten teeth without traditional metal braces, using virtually invisible aligners. Learn more about the market's leading clear aligner system.
