Dr. Willard comes from a business background but discovered chiropractic after a significant injury. He recognized that in many instances, with chiropractic care, surgery could be avoided. He decided to retire from corporate and return to school. Dr. Willard graduated cum laude from Palmer College in 2015. Shortly after graduation, he became board certified in atlas orthogonal, and upper cervical specialty. Dr. Willard's mission is to help people heal and return to a normal life, just as he has been helped through chiropractic care.

Referral information is supplied solely by chiropractic providers themselves and is not checked or warranted by the Oregon Chiropractic Association (OCA). Chiropractic providers who register as an Oregon Chiropractic Association Member pay specified annual membership dues. They are put on the Chiropractic Referral List as part of their membership benefits. Any and all chiropractic members who request to be listed on the Referral List are listed and, as a general rule, no one is excluded.

THE OCA DOES NOT RECOMMEND OR ENDORSE ANY OF THE LISTED CHIROPRACTIC SERVICE PROVIDERS. The OCA is not a health care provider, and does not give medical advice or treatment. The OCA offers the Referral List as a resource for patients looking for a chiropractic provider. However, the OCA does not pre-screen or pre-evaluate the facilities or providers in any way before they are put on the list. Nor does the OCA pre-screen, pre-evaluate, or consider the Medicare/Medicaid status of these providers. You are responsible for interviewing and selecting a suitable provider. Therefore, you should contact providers directly for relevant information, such as information on insurance coverage or specific techniques and services.

The OCA does not verify the credentials or licensing of any of the chiropractors before they are listed. If you wish to obtain a provider license status, please go to the Oregon Board of Chiropractic Examiners website.
