Soozy Martin
(Pickleball Professional)
Soozy is a marathon runner who has most recently completed
144 half marathons in 131 months. Prior to that, she played
tennis until her doctor told her running would be better for her
knees than tennis. Competition has always been part of her
game and once she stumbled onto Pickleball she was hooked.
Soozy plays 5 days a week and sometimes multiple times a day.
If you take a lesson from her, no doubt you’ll learn something
new every time. She’s fascinated by the rules and recently
completed referee training so keep an eye on those feet near
the kitchen.
