Dr. Langdon ultimately chose Palmer College because of the opportunity to participate in its Research Honors Program, where she was able to cultivate her interest in chiropractic research. Mentorship, which is the cornerstone of the Research Honors Program, was very impactful for Langdon, who said that learning from Dr. Stephen Onifer, Ph.D. was “monumentally impactful” on her learning.

Shanna Buller-Sáenz, D.C., (West, ’20) credits her desire to become a chiropractor because of the example her father and brother set.
“I became a chiropractor because my father and brother are both chiropractors. Growing up, I spent a lot of time in my father’s office. I got to see the benefits of chiropractic and how it truly changed people's lives.”
