An accomplished entrepreneur, Martha’s passion for helping people stay healthy led her to found both Fizika Group and now, b_Fizika, LLC, a Pennsylvania Benefit Company whose mission is to help advance brain health across a lifespan.

In January 2018, Martha was selected to work with Catamaran, LLC, a tech accelerator based in Harrisburg.  Together they are creating a beta version of Fizikaflex, a digital platform designed to help seniors stay healthy to reduce their risk of cognitive decline.  She appreciates the opportunity to work with a dedicated team of software engineers and designers who have helped form her vision for a tool that will help seniors at risk of dementia to continue to live independently and with dignity.
