Seth Alley, DC, CCSP, CKTP
Recognized Among Portland Monthly’s 2020, 2019, 2018, 2016, 2015 and 2014 Top Doctors
Originally hailing from the Lone Star State, Dr. Alley was born and raised in Austin. Spending time on the numerous rivers and lakes in Central Texas, he formed a strong appreciation for nature and the connection between a healthy, sporting lifestyle and improved function of the body. This connection plays a pivotal role in his chiropractic practice, as he encourages patients to seek better health through conscious choices in diet and activity that will enhance the body’s performance and longevity.
Dr. Alley graduated from Davidson College in 1999 with High Honors degrees in Spanish and Pre-Medical Studies and moved to Jackson Hole, Wyoming, to seek outdoor adventures on a grand scale. Between hiking, snowboarding, kayaking, and fly fishing, he worked as an on-call medical translator for Hispanic patients in the valley and volunteered with the Teton County EMS team as a medic.
In 2002, Dr. Alley enrolled at Western States Chiropractic College in Portland. Having been successfully treated by a chiropractic physician after a severe wake-boarding injury while in college, he had been spared surgical and narcotic treatments in favor of natural, conservative healing methods–an experience that drove him towards a goal of one day being able to provide the same life-altering, life-saving treatments for his patients. For Dr. Alley, there is no higher calling than to allow a patient the opportunity to regain his or her mobility and return to the activities of a healthy lifestyle, pain-free and trained to prevent similar injuries in the future.
Dr. Alley graduated Magna Cum Laude and Valedictorian from Western States in 2006, receiving the prestigious Clinical Excellence Award for outstanding patient care in the school’s clinic setting. He has performed internships in Portland, Oregon; Beverly Hills, California; Austin, Texas; and Jackson Hole, Wyoming. Preferring the relaxed and natural setting of Portland, he returned to the Rose City in 2007 to establish his private practice at Sylvan Chiropractic Clinic and Wellness Center.
Starting in 2013, Dr. Alley served six years as a member of the the investigative branch of the Oregon Board of Chiropractic, the Peer Review Committee. In 2019, he was appointed by Governor Kate Brown to an active position on the Oregon Board of Chiropractic and currently serves as the Board’s Secretary.

Aja Ngo, LAc
My father was a significant influence in my life, introducing me to acupuncture at the age of thirteen. My journey started through training in both Swedish and Sports massage at the Pittsburgh School of Massage Therapy. In 1997 I was invited to study the Chinese massage style called Tuina at The Academy of Chinese Medicine in Beijing, later mastering Shiatsu massage. I have been teaching and practicing both for over 20 years. I graduated from Tai Sophia Institute in Maryland—one of the oldest accredited acupuncture schools in the country—with a specialization in Five Element Acupuncture in 2001. After graduating, I traveled to Asia to acquire a more complete experience of acupuncture which led to the origin of my practice. I studied electrical acupuncture in Vietnam in a Catholic monastery in Bien Hoa. The concept of treating paralysis through acupuncture emerged in my clinical practice after witnessing patients treated during my time at the monastery. In 2007, my husband and our two sons moved to the Portland where I continued to expand my scope of work by adding Japanese needling techniques and moxibustion to my practice. Since graduating from the Tai Sophia Institute, I have practiced in three different states and have taught both shiatsu and acupuncture in the U.S. and the Czech Republic, conducting classes focused on medical acupuncture for licensed physicians. I am incredibly grateful for these experiences, as they have given me a solid foundation from which to draw. They have enabled me to be able to view client’s symptoms through many different lenses and subsequently offer the best possible treatment plan. When I am not helping patients, I enjoy spending at the Hoyt Arboretum, biking, reading, paddle boarding, creating glass mosaics and tango dancing.
