Mandy Sumner

World Champion Freediver / PADI Freediver Instructor Trainer


Growing up a water baby on the coast of southern Maine, Mandy Sumner learned to swim before she could even walk. “I think my love for the water was engrained in me before I was even born,” she says. She started competing on the swim team at the age of five and continued throughout grade school, high school and beyond.

Sumner began freediving in March 2014 in Hawaii and fell in love with the sport immediately. She began taking courses to learn as much as she could. A competitor by nature, she entered her first international competition within two months of her first freedive.

Over the past two years, Sumner has traveled the world to compete. In 2015, she became the first world champion and gold medal winner, man or woman, in United States history. “It’s been an incredible journey learning new things every day, meeting amazing people all over the world and promoting safe and happy freediving to freedivers young and old, beginners to elite,” she says.

With a Bachelor’s degree in geology and Master’s degree in geographic information systems, Sumner was a geologist/GIS analyst for 15 years until she set her career aside for her passion of freediving. Now a PADI Freediver Instructor Trainer, she is excited to work with PADI teaching freediving all over the world.

Her mission: to share her passion for the beauty, love, safety and respect of freediving and our oceans.
