About Dr. Seth Alley
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. 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. He is a Certified Chiropractic Sports Physician (CCSP) and has extensive training in the treatment of dance-related injuries from the Harkness Center in New York City. He has been a treating physician for Oregon Ballet Theater since 2010. Dr. Alley has been recognized among Portland Monthly’s 2022, 2021, 2020, 2019, 2018, 2016, 2015 and 2014 Top Doctors and Complementary Providers.

There's a reason why Sylvan Chiropractic is consistently named by readers/patients as one of Portland's top chiropractic practices..
February 18, 2025Mark P.Verified patient
Dr Seth is a great person and Dr. I highly suggest that you see him.
He asks clear questions about what type of adjustments I’m comfortable with and what makes me uncomfortable.
Let’s face it, we have phobias that contribute to often not getting the body care we need.

Great experience with Dr Seth and Gretchen. Dr Seth took the time to read my chart, ask questions and listened to my concerns. He suggested an alternative approach since I am uncomfortable with neck adjustments, it was really cool. I left feeling cared for and out of pain for the first time in months. Highly recommend seeing Dr. Seth!!

Dr. Alley is a knowledgeable, informative, effective and fun Chiropractic doctor to go to. He's been my & my son's chiropractor for about a year, and he does an excellent job of keeping us tuned up, and the annoying little aches and pains away, so the bigger pains comes don't come back.

This was not the first time I have seen Dr. Alley. Each time he was able to diagnose and treat my problem. Everyone at this clinic is really friendly. It was easy to get an appointment online when I was at Disneyland and hurt my back. I am very satisfied with the care I received.
