Stephanie Apostol

COO/Senior Analyst

Wholeheartedly curious and wired for creative and collaborative problem solving, Stephanie Apostol is obsessed with the art and science of market research.  Since 1996, she has guided  local, national and international clients in hundreds of research initiatives. Her favorite aspect of research is bringing peace of mind to her clients by getting them trustworthy data that informs their strategy and answers the questions that keep them up at night.

Ms. Apostol enjoys the challenge of designing innovative yet practical approaches to data collection and reporting. Sometimes this means executing a simple web survey but other times it means implementing a complex multi-mode data collection approach, creating custom project management software, or integrating data from several sources into a dynamic dashboard reporting tool.

Stephanie is thankful to be a part of a company where going the extra mile is business as usual because going above and beyond is in her DNA.

Ms. Apostol, a principal owner of WestGroup, also serves as COO and President of its Board of Directors.  She is a RIVA trained moderator and a past president of the Arizona Chapter of the American Marketing Association.  Stephanie, a proud graduate of Penn State University,  holds a Bachelors of Science in Psychology and a Masters in Business Administration. She currently serves as Vice President of Philanthropy for the National Charity League – San Tan Chapter, where she and her daughter are members.
