Dee Riggins

Office Manager

Dee Riggins comes to New Leaf Center after a 30-plus year career in client service, customer service and retail sales auditing.

Dee started her career as a client service representative with Sentinel Direct, the direct marketing division of The Orlando Sentinel, a Tribune Media product. Dee earned several Presidents Awards for outstanding client service as a member of several teams during her tenure at the Sentinel.

A part-time, seasonal job while working there led to a career change and an opportunity to be part of the team that opened the first Kohl’s department store in Central Florida. Dee served as an Ad Set Associate and subsequently was promoted to Ad Set Team Leader, spearheading the store’s employees who were responsible for posting and ensuring the accuracy of the store’s merchandise signage. In March 2011, Dee’s store was the first to receive a perfect score on its signage that year from Kohl’s national auditing team during one of its surprise audits.

Dee spent the last nine years working for California-based Advantage Sales and Marketing (ASM). As a Retail Sales Representative for this national company, she served on a team whose primary responsibility was to ensure national products – such as Smuckers, Ferrero Rocher and Marzetti – received proper store placement to meet their sales goals. In addition, Dee conducted monthly audits on a national retail drug chain to ensure its stores were compliant with all HIPPA, ADA and FDA regulations. None of Dee’s stores flunked their federal audits during her time working with both the pharmacy and store managers.

Dee is a 1986 graduate of Old Dominion University in Norfolk, Va., and a native of that city. She is an avid fan of women’s collegiate basketball and the WNBA.
