About Us

Dr. Jordan Duncan was born and raised in Kitsap County and graduated from the University of Western States in 2011 with a Doctor of Chiropractic Degree.


Since he was in high school, dealing with his own injuries, Dr. Duncan knew that he wanted to help people in pain. He has made a great effort to search for and learn effective methods of assessment and treatment for people with painful musculoskeletal conditions.


Dr. Duncan is one of a small handful of chiropractors in the state of Washington to be certified in the McKenzie Method of Mechanical Diagnosis and Therapy (MDT), a reliable evidenced based method of assessment and treatment.


In addition to treating a diverse patient population, Dr. Duncan enjoys treating athletes and has worked with numerous high school, collegiate and professional athletes. As a former competitive athlete and a current long distance runner, he knows what it’s like to deal with acute and chronic injuries and the importance of returning to a sport as soon as possible. He believes that active care and proper education are crucial in the process of recovery and strives to empower patients with tools to help themselves.


In addition to his MDT training, Dr. Duncan is also proficient in Pain Science, Dynamic Neuromuscular Stabilization, RockTape, Neurodynamics, and Functional Rehabilitation, which allow him to provide a comprehensive treatment for patients in all phases of care.

When not in the clinic, Dr. Duncan can be found attending  numerous seminars and soaking up new information. He is an avid runner and has competed in several full marathons and half marathons, as well as numerous shorter distance races. He also volunteers with Special Olympics and was a member of the Washington unified softball team that competed in the national games in Seattle in 2018. 


What To Expect

Plan on arriving to the clinic 15 minutes prior to your first scheduled appointment.  There will be a few forms to fill out, some of which will provide us valuable information regarding your care in which to guide progress.


Please dress in clothes that will allow you to be able to move around in, since you will likely be moving around during your examination.


Your entire first appointment will last about an hour, and will include history taking, the physical examination, clinical decision making, and treatment if warranted.  


Our goal is pain investigation, and during this mission our goal is to become like a detective where the pain is the victim and we are looking for the culprit.  


In order to gain more information, you will likely be asked to continue the assessment process at home to gain more data and report back want happened. This will enable us to diagnose and classify you better which will lead to the best possible treatment.


If we don’t think we can help you, we will refer you to the practitioner who we think can.


Subsequent visits won’t last as long as the initial one, but will build on the previous visits and should help us either confirm or refute the initial hypothesis, with the goal of accurate classification and better treatment. 


The focus will be on active care, education, and patient empowerment.

About The McKenzie Method

The McKenzie Method, also known as Mechanical Diagnosis and Therapy (MDT), is a method of self-care and prevention that involves active patient involvement and education for back, neck and extremity problems. It was initially developed by Robin McKenzie in New Zeeland in the middle of the 20th century, and now has a large and quickly growing base of research support.


The McKenzie Method is an assessment method and treatment approach for all musculoskeletal conditions. As a system of classification based on the symptomatic and mechanical presentation to movements and postures, it guides clinical decision making and treatment during the duration of care as well as prevention of future episodes.


There are several myths that surround the McKenzie Method, for example that it is a series of “McKenzie Exercises”, that it is only for back or neck pain, or that it is a tool in your toolbox to go to if another tool doesn’t work.


The MDT system more than just a treatment technique. Instead, it is a way of thinking guided by a thorough assessment process. The assessment is the key, which leads to accurate diagnosis, which determines the treatment, which ultimately should yield a favorable outcome.


The McKenzie Method is also very effective for extremity conditions as well as spinal problems, and is a very reliable system in pinpointing where the problem is coming from.


Another beauty of the McKenzie Method is that it can spot early on in the process who should respond and who won’t. If the patient needs a different form of care, the system will let the patient and clinician know earlier than later.
