Our Educational Team

Ken Gracey

CEO and brother of founder Chip Gracey, Ken has put Parallax education at the forefront of his priorities.  Ken’s vision and direction has lead Parallax to become the dedicated educational institution it is today.  He started with the Stamps in Class series, putting Boe-Bot Robots in the hands of teachers all across the Unites States. Today, you will still find him working tirelessly with educators to ensure that they are set up for success with top-of-the-line hardware and thoughtfully-written tutorials for the classroom.

Stephanie Lindsay

Stephanie is the editor and author of many of the tutorials and texts we’re proud to offer online for students, teachers, and self-learners everywhere.  She is a guiding hand to the entire department, and instrumental in helping Parallax achieve its educational goals.  She lends her skills towards pushing Parallax forward by overseeing product development, asking the tough questions, and keeping our focus on the intended destination.  Stephanie is also a great point of contact for new and returning educators, as her knowledge of our history and products is beneficial when answering questions or helping educators fulfill their classroom goals.

Andy Lindsay

Engineer and author of many of the educational textbooks students have learned from over the years, Andy played the pivotal role in bringing our educational vision to life. Nearly all of what you read on our Learn website or in our educational textbooks comes directly from, or is inspired by Andy’s work.  As anyone who has ever read his books will attest, Andy’s writing is diligent and multi-faceted; he will always endeavor to provide simple functionality and thoughtful-design in his code and in his lessons.  The success we and our teachers enjoy in educator’s courses is due in large part to Andy’s influence and design, and he is a very valued member of our team.

Jeff Martin

As a college student Jeff learned and mastered the BASIC Stamp 1 and soon after took a job supporting it and other products here at Parallax. He's worked in tech support, IT, management, and now in our R & D department as Senior Software Engineer. If you're enjoying programming with BlocklyProp, Jeff is one of the people you can thank! Jeff is kind and considerate person. His patience level for answering questions and providing design assistance is extraordinary by most measures. Jeff's personal hobbies include cycling, camping, kayaking and enjoying time spent with family.
