Kristine Betancourt - Assistant office manager

Chiropractic St Augustine FL Kristine Betancourt

Kristine Betancourt and her family recently moved to St. Augustine, FL from Jacksonville, NC, where her husband, Raul, served in the United States Marine Corp for over 20 years of faithful service. She has three children Darian (23) currently serving in the Air Force, Liliana (18) a recent high school graduate, and Raul (16) a junior in high school. In the family's spare time, they love to explore new places.

Kristine was born and raised in NY where she focused on a career in advertising as a traffic coordinator.

Prior to moving to St. Augustine, Kristine worked the last 11 years as an administrative assistant in a private preschool coordinating staff and students daily activities. When she wasn't at school, overseeing children or building new relationships with families, you'd find her at the real estate office assisting families with house hunting and relocating to the area.

Embarking now on a new journey, Kristine is excited to be the face you'll see as a patient of Back in Motion.

Elaina Dodi - Chiropractic Assistant

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.
