Joanna Hillier, Certified Medical Assistant


Florida native. Certified medical assistant through the AAMA since 2010 with strong history in individualized care. Worked in family practice for 5 years and orthopaedics/traumatology for 2. Firm believer in the treatment approach here at Optimyze that focuses on the combination of our clients individual concerns and thorough medical history and diagnostic testing. Looking at things most physicians don’t and providing care that seeks to fix the problem instead of masking the symptoms.
