Dr. Ryan Nienaber, D.C., B.S.

 Boones Ferry Chiropractic and Massage


Dr. Ryan Nienaber was born in Victoria BC, Canada where he grew up and attended school. During elementary school, he competed in multiple track and field events with long distance running being his forte. Over the next couple of years he played rugby, which was the precursor to his first chiropractic experience.

Dr. Ryan continued seeing a chiropractor over the years for various ailments, as he stayed extremely active in sports and weight trained on a daily basis. It wasn't until he was hit in a head on collision while riding a motorcycle that he truly experienced the power of chiropractic. He had been under the care of multiple specialists in the medical field for many months without any signs of relief. It was during this time that he became frustrated with traditional medicine (taking pain killers and muscle relaxers) and decided that he needed to pursue something else. Dr. Ryan began seeing his chiropractor and immediately saw results. The daily headaches were eliminated, the "fogginess" in his thought process was lifted, and he was able to return to his previous level of physical fitness. For Dr. Ryan, it was a life-changing event that made him excited to pursue chiropractic as a potential profession. It made so much more sense than merely masking a symptom, and he wanted to help people the way his chiropractor helped him.

In 1998, Dr. Ryan moved to Portland, Oregon to attend the four-year program at University of Western States. He played an active role in campus life as an elected officer of the student body. He was able to continue to weight train and kickbox during his time at school, and then started to pursue his passion of training in Muay Thai with Brazilian Jui Jitsu. This sports background has really solidified his understanding of sports related injuries and given him a valuable edge in treating such injuries in his practice today.

Outside of work and sports, Dr. Ryan enjoys spending time with his wife, Jennifer, two young boys, Noah and Paxton, and two Boxers, Nalla and Bauer.

Dr. Dan Burnett, D.C., B.S.

Dr. Dan Burnett has lived in Oregon his whole life, attending Tigard High School where he played football and baseball during his teenage years.  His first chiropractic experience was when he was 16. He had been involved in a serious automobile accident leaving him with injuries to his neck and back.  This accident ended up being a blessing in disguise as it was the precursor to his introduction to the diverse and effective field of chiropractic. He was so impressed with the treatments that he wanted to be able to do the same for other people.

After high school, Dan attended Oregon State University (OSU) and graduated with Bachelors of Science, majoring in exercise and sports science, with a minor in chemistry.  This degree really peaked his interest in sports conditioning where he could apply it to baseball, weight training, and jui jitsu.

With his continued participation in sports, Dr. Dan has been exposed to a variety of injuries, and he has always been able to be treated with chiropractic care with amazing success and no long-term impairment. 

In 2009 Dr. Dan graduated from Western States Chiropractic College (WSCC) with a Doctorate in Chiropractic.  At WSCC, he tutored neuromuscular diagnosis and biomechanics, which was a valuable experience for him as it solidified Dr. Dan’s understanding on these topics.  During his schooling he completed the applied kinesiology curriculum, studying over 100 hours of the specialized muscle technique system. 

Dr. Dan likes to spend his free time in the gym lifting weights, or participating in martial arts.  In the spring and summer months he enjoys hiking, golfing, and white water rafting.


Dr. Sun Yun, Pharm.D., M.Ac.O.M., Dipl. O.M., L.Ac

Dr. Sun Yun, Pharm.D., M.Ac.O.M., Dipl. O.M., L.Ac., is a graduate and current teaching assistant at the Oregon College of Oriental Medicine (OCOM).  Immediately post-graduation, Sun spent two months in Nepal with the Acupuncture Relief Project, providing free primary care and medical support to those with limited access to immediate and reliable healthcare.  He has now joined our team of passionate and dedicated natural healers to address a wide array of musculoskeletal ailments and conditions.  

Sun began his journey into the medical field by obtaining his doctorate in pharmacy.  He practiced for 10 years as a pharmacist before shifting gears to pursue traditional Chinese medicine (TCM).  Dealing with multiple surgeries for sports-related injuries himself, Sun set out to explore less invasive options to the western medical paradigm of pharmaceutical and surgical interventions for pain relief and recovery.  With TCM, he discovered a path leading to a more natural, holistic, and balanced state of well-being and healing.  Combining both his western and eastern medical knowledge, Sun incorporates the “best of both worlds” in his approach to healing and recovery.  He utilizes acupuncture, herbal medicine, biomedical physical and orthopedic assessments, and a wide array of auxiliary healing modalities, including cupping, gua sha, moxibustion, electro-stimulation, Tuina massage therapy to effectively address the root cause of the condition.  

In his free time, Sun enjoys sports, exercise, martial arts, reading, and traveling.
