Mariel Galdiano Bio
Mariel Lancy Galdiano (born June 25, 1998) is an American professional golfer from Honolulu, Hawaii. She first gained national attention as a teenager when, at age 13, she became the youngest golfer to compete in the 2011 U.S. Women’s Open. Galdiano has since developed into one of the most decorated amateur golfers in recent American history, claiming major junior, collegiate, and international titles before turning professional in 2020.
After several seasons sharpening her game on the Epson Tour, Galdiano earned her LPGA Tour card for 2025 by finishing tied for 13th at the LPGA Final Qualifying Tournament in December 2024. Her blend of early prodigy experience, amateur championship pedigree, and patient path to the top flight of women’s golf has shaped her reputation as a focused and steady competitor.
Early Life and Background
Mariel Lancy Galdiano was born on June 25, 1998, in Honolulu, Hawaii, where she grew up surrounded by the island’s strong golf culture. From a young age, she trained in a region with year-round playing weather and a deep pipeline of junior talent. That environment helped her develop a smooth, repeatable swing and an early comfort with competitive tournament golf.
Galdiano attended high school in Hawaii and quickly established herself as one of the top scholastic players in the state. She became a three-time Hawaii High School Athletic Association champion, a feat that underlined her consistency and ability to perform under pressure in a program familiar with producing elite golfers. Her teenage results placed her firmly on the radar of national selectors and college recruiters.
Following her standout high school career, Galdiano continued her development at the University of California, Los Angeles (UCLA), one of the premier college golf programs in the United States. The move paired her with elite coaching, strong practice facilities, and a competitive schedule that bridged the gap between amateur and professional golf.
Path to Professional Golf
Galdiano’s early exposure to elite competition came in 2011, when, at just 13 years old, she became the youngest golfer in the field at the U.S. Women’s Open. The experience of playing a major championship at such a young age provided a valuable baseline for the demands of professional golf. She returned to the same tournament four years later and made the cut at the 2015 U.S. Women’s Open, having won her sectional qualifier to earn entry.
During her amateur years, Galdiano built a résumé that included the 2015 Canadian Women’s Amateur title and a memorable showing at the 2017 Summer Universiade in Taipei. At that event, she won the individual gold medal and helped lead the United States to the team gold medal, one of the strongest international amateur performances by an American collegiate golfer that year. These results reinforced her standing as a future prospect for the LPGA Tour.

Winning her sectional qualifier added another layer to the accomplishment, demonstrating that she could grind through qualifying rounds and then perform once she reached the championship venue.
Her biggest amateur moment arrived at the 2017 Summer Universiade in Taipei, where she won the individual gold medal and helped the United States claim the women’s team gold medal. The double gold confirmed her status as a leading collegiate amateur and positioned her for an eventual transition to the professional ranks.
Epson Tour Years (2020–2024)
