Amanda Brynn Mickelson is the eldest child of golf champion Phil Mickelson and his wife, Amy. She has never chased fame herself. Still, her name keeps surfacing in golf history, because two of her biggest life moments collided with the U.S. Open. Her birth came one day after a famous 1999 finish at Pinehurst. Her high school graduation led her father to skip the 2017 tournament entirely.
This biography covers what the public record actually shows about Amanda Brynn Mickelson: her family, her education, the notable moments, and where she stands today. Public information about her is limited, and this article sticks to reported facts rather than filling gaps with guesses.
Who Is Amanda Brynn Mickelson?
Amanda Brynn Mickelson is an American private citizen and the first child of Phil and Amy Mickelson. She was born on June 21, 1999. That date matters to golf fans because her father finished runner-up at the 1999 U.S. Open the day before.
She became known publicly in 2017. That year, she served as class president at Pacific Ridge School in Carlsbad, California, and gave the commencement speech. Her father withdrew from the U.S. Open to hear it. She then went on to Brown University, where she studied Egyptology.
Today, Amanda keeps a low profile. The press does not cover any public career for her, and she has not given interviews about her life.
Amanda Brynn Mickelson’s Family Background and Relationships
Parents: Phil and Amy Mickelson
Her father, Phil Mickelson, ranks among the most successful golfers of his era. He is a six-time major champion and a three-time Masters winner. Her mother, Amy (née McBride), met Phil in 1992. At the time, Amy was a junior at Arizona State University and a Phoenix Suns cheerleader. The couple married in 1996.
Siblings: Sophia and Evan Mickelson
Amanda is the oldest of three children. Her sister, Sophia, arrived in 2001. Like Amanda, Sophia earned an Ivy League education, studying architecture at Columbia University. She also appeared in the 2019 film Ruta Madre. Their brother, Evan, was born in 2003. He plays golf casually but has not pursued it professionally.
Grandparents
On her father’s side, Amanda’s grandparents are Phil Mickelson Sr. and Mary Mickelson. Both followed their son’s career closely for decades. Mary, a San Diego native, played basketball in her youth.
Education, Career, and Personal Identity
Amanda attended Pacific Ridge School, a private school in Carlsbad, California. By her senior year, she was class president. In June 2017, she delivered the commencement address at graduation.
That fall, she enrolled at Brown University in Providence, Rhode Island. Multiple outlets reported that she planned to study Egyptology. Her choice drew attention because her family is famous for sports. A 2026 family profile by Us Weekly confirms she attended Brown and studied the subject.
Beyond her studies, there is no verified public record of Amanda Brynn Mickelson’s current job or career. Some websites list a net worth, a height, or a profession for her. None of those figures come from reliable sources, so this article does not repeat them.
Important Public Mentions and Notable Moments
Born the Day After the 1999 U.S. Open
In June 1999, Amy was close to her due date while Phil played the U.S. Open at Pinehurst. He kept a pager in his bag and planned to leave if labor began. Payne Stewart won by a single shot with a par putt on the final hole. Afterward, Stewart held Phil’s face and wished him luck with the baby. Amanda arrived the next day.
That exchange became one of golf’s most retold stories, especially after Stewart died in a plane crash later that year.
The 2013 Eighth-Grade Graduation
Amanda’s school milestones and the U.S. Open overlapped more than once. In 2013, the U.S. Open took place at Merion that week. Phil flew home to California for her eighth-grade graduation. He then returned in time to play, and he finished runner-up again.
Skipping the 2017 U.S. Open
Her high school graduation fell on June 15, 2017, the opening day of the U.S. Open at Erin Hills, Wisconsin. Phil told the USGA ahead of time that he would likely miss the event. He held out hope for a weather delay, but clear skies ended that chance, and he officially withdrew.
The decision stood out because the U.S. Open is the only major missing from his career Grand Slam. According to USA Today, Phil said Amanda understood how much the tournament meant to him. He added that she would have accepted it if he played. He chose to attend anyway, explaining that some life moments are too important to miss.
Phil’s Public Praise
In a 2016 interview cited by Heavy, Phil said he learned from his daughter. He also shared that she traveled to India at 16 to teach children in a remote, high-altitude village.

The Personal Side of the Story
What makes Amanda’s story interesting is not celebrity. It is the way her life repeatedly tested her father’s priorities in public. Phil spent decades chasing a U.S. Open title. Twice, he arranged that chase around his daughter’s school events.
Amanda herself has stayed out of the spotlight. She does not appear to keep a public social media presence tied to her family name. She has also made no public statements about her personal life. Claims online about a boyfriend, husband, or marriage have no reliable sourcing. As far as the public record shows, her relationship status is private.
Recent Public Visibility
Amanda Brynn Mickelson has made very few public appearances in recent years. Her family name returned to headlines in 2026, but not because of her directly. Early that year, Phil missed several LIV Golf events to be with his family during what he called a family health matter. In April 2026, he withdrew from the Masters for the same reason and said he would be away for an extended period.
Phil did not say which family member was involved or share any details. Any article linking that matter to Amanda specifically would be speculation.
