Dr. Aixa Santos

Originally from Vega Baja, Puerto Rico, Dr. Aixa Santos graduated from the University of Puerto Rico in 2015, having earned the degree of a Bachelor of Science in Biology. She then furthered her education by earning her Doctor of Chiropractic Degree from Sherman College of Chiropractic, in Spartanburg, SC. During that time, Dr. Santos participated in Blair Chiropractic Technique seminars and conferences. After graduation, she decided to move to Seattle to work with Dr. Michael Lenarz as an associate doctor.

Dr. Santos came to Health First to make a difference in the world by changing people’s lives and restoring and maintaining optimal health. She embraces the understanding that by removing misalignments to the spine, we remove obstacles to healing and allow the body to heal itself.

Dr. Santos practices at our Seattle location, and occasionally we are lucky enough to have her at the Sedro-Woolley location.

She completed a four-month program in dynamic myofascial techniques with an instructor named Dawn Schmidt, LMT.
