Mina Margraf was born on May 18, 2003 in Portland, OR to Scott and Michiyo Margraf. She has an older sister, Aya, a younger sister, Maika and two dogs named Tama and Mame. Currently, Mina is an honor student at Laurel Springs School and she will graduate in 2021.
When Mina's family was stationed in Sasebo, Japan due to her father’s military duty, her parents signed up Mina and her sister in a small gymnastics club when she was two years old. Since both of the girls had so much energy, Mina's parents thought it was a great idea for them to release extra energy at gym. Mina's parents had been declining a team participation offer due to military relocations until they moved to California. Mina started competing level 4 in 2012 at American Gymnastics Academy of Long Beach. She placed first in the all-around with a 38.100 and first on vault with a 9.700 at the SoCal State Championships. Mina then moved to Hawaiian Island Twisters where she trained until 2016.
Mina moved up to level 8 for the 2015 season, finishing first in the all-around with a 37.725 and first on all events at the State Championships. She qualified to the Region 2 Championships where she placed second in the all-around with a 37.700 and first on uneven bars and floor exercise. In 2016 as a level 9 gymnast, Mina placed first in the all-around, first on vault and floor exercise, second on balance beam and third on uneven bars at the State Championships. Mina did well at the Region 2 Championships, finishing second in the all-around with a 37.100, first on floor exercise and second on balance beam. She qualified to the Level 9 Western Nationals where she placed 12th overall and second on floor exercise.
Following Mina's 2016 season, her family relocated to Texas, so she started training at World Champions Centre in Spring, TX. She started competing level 10 for the 2018 season. At the State Championships, she placed third on balance beam with a 9.500. She had a great meet at the Region 3 Championships, finishing second in the all-around with a 37.400, second on vault and sixth on balance beam and floor exercise. She qualified to the Junior Olympic Nationals in Cincinnati, OH where she placed 13th overall with a 37.700 and fourth on vault. In 2019, Mina placed fifth in the all-around and second on balance beam at the State Championships. She qualified to the Junior Olympic Nationals after finishing second in the all-around with a 38.025 and first on balance beam and floor exercise at the Region 3 Championships.
Mina trains 29-34 hours per week at World Champions Centre in Spring, TX under coaches Laurent Landi and Cecile Canqueteau-Landi. She is working hard to qualify to the Junior Olympic Nationals again. Her long-term goal is to compete for a college gymnastics team.
