Meet the Doctor

  • Dr.
    David Corll

    Dr. David Corll graduated from Western States Chiropractic College in 2000 with a Bachelor's degree in Human Biology and a Doctorate in Chiropractic.  Dr. Corll opened a private practice at the public clinic at the college and worked with the research department for a study funded by the National Institute of Health. 

    In 2004 Dr. Corll opened Compete Care Chiropractic in Wilsonville.  His care includes manual adjustments, instrument adjustments, range of motion exercises, electrical stimulation, mechanical traction and laser treatment.  In 2016, Dr. Corll purchased a K-laser for the treatment of pain and range of motion restrictions.  Patients are able to see a significant increase in their healing and a decrease in pain when their treatment includes the K-laser.  This technology, in combination with the team of massage therapists, has been found to be very helpful in the quick resolution of patient's symptoms. 

    Dr. Corll served on the Oregon Board of Chiropractic Examiners Peer Review Committee for almost five years, most of that time holding the position of committee chair.  He is a member of the American Chiropractic Association and was an Adjunct Instructor For the University of Western States.

  • Dr
    Sarah Colby

    Sarah Colby, Chiropractic Physician, has been practicing since 1991. She graduated from Palmer College of Chiropractic-West in San Jose and had a clinic in San Francisco for many years. She has been practicing in Wilsonville, Oregon for the last 18 years. 

    Her clinics were inside of Pilates studios and health clubs for many years and she has had extensive training in sports injuries and exercise rehabilitation. Patients frequently say she is an excellent listener when hearing about their conditions. She evaluates the cause of pain and injury by looking at joints, alignment, muscles, nerves, posture, activities, and ergonomics. Her comprehensive approach to treatment might include regular and non-force adjusting, muscles work, and exercise rehabilitation.

    When she is not helping patients feel better she tromps around Oregon hunting truffles with her dogs and promoting healthy forests.
