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.

Joanna loves the outdoors here in East Tennessee, doing anything from hiking, tennis or enjoying the farmers markets with her dog Margaret. On rainy days, she enjoys almost any craft, including sewing, woodworking, jewelry making, beer and cider brewing, napping and learning new things.
