Elaina Dodi and her family moved to St Augustine a few years ago. She and her husband of 24 years always planned that Florida would be their ultimate destination. She has three children, John, Jr who has graduated college and currently lives in Tampa, Felicia who is currently finishing her Medical Assisting Program, and Matthew who is in High School. They look forward to getting together and having family time.

Elaina was born and raised in NY where she graduated college with a degree in Office Technologies. While in NY she worked as an Administrative Assistant for 10 years. She had taken time off to raise her family, and during that time, she moved to various states due to her husband’s career. Once her children were grown, she went back to work in a school system as a Teacher’s Assistant to Special Needs children, which she felt was refreshing and rewarding.

Elaina is very excited to start her new path and be one of the faces you see at Back in Motion and is ready to help you get on your path to feeling better.
