I originally hail from the Lone Star State, having been born and raised in Austin. Spending time on the numerous rivers and lakes in Central Texas, I 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 my chiropractic practice, as I encourage patients to seek better health through conscious choices in diet and activity that will enhance the body’s performance and longevity.

Graduating from Davidson College in 1999 with High Honors degrees in Spanish and Pre-Medical Studies, I moved to Jackson Hole, Wyoming, to seek outdoor adventures on a grand scale. Between hiking, snowboarding, kayaking, and fly fishing, I divided my professional time between my business as an on-call medical translator for Hispanic patients in the valley, and my volunteering with the Teton County EMS team as a medic.

In 2002, I decided to further my career in healthcare by attending Western States Chiropractic College in Portland, Oregon. Having been successfully treated by a chiropractic physician after a severe wakeboarding injury while in college, I had been spared surgical and narcotic treatments in favor of natural, conservative healing methods. This experience was a turning point for me, as I realized that my goal in life was to one day be able to provide the same life-altering, life-saving treatments for my patients. For me, 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.

I 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. I have performed internships in Portland, Oregon; Beverly Hills, California; Austin, Texas; and Jackson Hole, Wyoming. Preferring the relaxed and natural setting of Portland, I returned to the Rose City in 2007 to establish my private practice at Sylvan Chiropractic Clinic and Wellness Center.

Tracy Siegel, MPH, NTP

I have always been passionate about health, wellness and especially nutrition. That’s why I got into health care in the first place. Even though the business side of healthcare wasn’t a source of joy for me, it offered a breadth of experience and a tremendous platform for my next adventure. After the birth of my son in 2011, I decided to take some time off to be a mom, but also to reignite my passion and figure out what was next for me. During that time, our family experienced significant health events. While everyone is doing great today, it was a pretty scary time for all of us. As a result of the emotional stress, I experienced some health issues myself.  I saw my practitioner who told me ‘I don’t know how to help you.’ That was my call to action. I decided in that very moment to take charge of my own health. To be my own advocate. Shortly after, I went back to school and I became my own first client. Now I live to inspire people like you to transform your life like I did, with food, exercise and stress reduction.

I’ll teach you how to eat really amazing healthy food – that is also incredibly yummy and satiating! And it’s all based on your bio-individual composition. For example, you might be doing things that are leading to inflammation. And, an inflamed body cannot lose weight, at least not easily or sustainably. Or, perhaps, your constant exposure to emotional stress is causing damage to your adrenal health. We’ll also have discussions on your bloodwork or other test results that you’ve had that can give us clues to what you need. Addressing your individual situation will allow me to make nutritional recommendations based on your specific needs.

So, if you’re not feeling your best, there’s no better time to schedule a free consultation with me! I’m confident I can help you with the same compassion and care that I give my own family and friends. We can meet in person in my office, or virtually if that’s better for you. You can contact me directly at (503) 810-1791 or learn more at my website, Pure Nutrition!
