Meet our Board
of Directors
Dave Graff
Founder & Board Chairman
Dave retired in 2022 as President of Graff Group Market Intelligence based in Minneapolis, Minnesota. Dave currently heads up 333Pathways, a boutique book publisher who recently published his wife’s memoir, 6 Kids And A Ping Pong Table.
Dave attributes his inspiration to create Playtime Tech to his awesome granddaughter who was 18 months old and became the first user of a Toddler Playboard. She served as Chief Kid Officer of Playtime Tech in its early stages and Dave was on a mission to make a significant difference in the lives of toddlers. Playtime Tech became a Minnesota nonprofit organization in 2018 for the primary purpose of bringing hope, joy and learning to kiddos dealing with significant health issues.
To sum it up, Dave’s all about Playboards, Publishing and Pickleball. He became a USA Pickleball Ambassador and Certified Pickleball Coach in 2023 and takes great pleasure in teaching friends, family and beyond to enjoy pickleball.
