Erika Johanson, Service Coordinator-Boca Ranton

Erika was born and raised in Duluth, MN.  In 1999 she relocated to Las Vegas, NV to evade the harsh MN winters.  Shortly after moving to Las Vegas she was hired by Cenegenics and had the pleasure of working with its founder Dr. Alan Mintz and many of the original team members.  She served in many varied capacities during her time in Las Vegas including Physician Affiliate Services Coordinator and Media coordinator.

In 2008 she transferred to the Boca Raton center to be closer to family in Florida.  After a brief sabbatical she rejoined the Boca team in 2014 and is focused on patient retention and error reduction.  She is currently pursuing a bachelor’s degree in Health Management.
