Chelsea G Foster

Chelsea Foster is a graphic designer and brand consultant based out of The Grotto Community Center in York, PA.

Tetra’s primary work comes in the form of graphic and web design. Chelsea’s specialty is in branding and marketing development and her work can be seen in children’s workbooks, posters, mailers, postcards, textbooks, social media, digital platforms and beyond.

When not at the studio Chelsea enjoys spending time with her family, riding her motorcycle, traveling, baking and reading books.

Tiffani J Spangler

Tiffani Spangler is data lover, relationship builder, book nerd and usually thinking about her next motorcycle ride.

In her mind she never felt confined to one business field; she loved them all. She enjoyed her CPG days of sifting through consumer and macro-economic data trends which provided insights into consumer purchasing behaviors. This role then led to national demand planning for over 2,000 SKUs and eventually back to sales where she distributed multi-million-dollar brands to grocery stores all over the U.S.

Life granted her permission to partner with Chelsea full time as the demand for Tetra’s services grew. Tiffani leads Tetra’s business strategy, development and project management efforts.
