Stephanie Stohrer

Executive Assistant

Stephanie received her Bachelor of Science degree in Marketing from Rowan University. Upon graduation, she began her career as a Market Research Analyst with Information Resources, Inc., working with investment banking clients, before taking on Ferrero USA as her primary client. After some time with IRI, Stephanie accepted a position as a Grocery and Trade Marketing analyst with Ferrero USA, supporting the sales and trade marketing teams. As much as she loved her analyst role, once she started a family with her husband, she took a step back from the corporate world to focus on her two children.

During this time, she maintained “one foot in the door” by substituting in local schools and accepting positions where she could work from home doing administrative work, payroll services, and online marketing. She has also had several volunteering positions, such as Breastfeeding Counselor with Breastfeeding USA, Committee Member/Emcee for town-wide talent show, Girl Scout Troop Leader, and various other positions within her children’s lives. As an avid reader and writer, she is also currently doing behind-the-scenes work for a well-known history podcast.

Nutrition Link Services was a perfect fit for not only her skill set, but also her passion for promoting health and wellness. Stephanie found that Nutrition Link Services was exactly the kind of company at which she wanted to be employed, and she is proud to be back doing such meaningful work in an incredibly important field.
