Who Is Haley Alonso?
Haley Alonso, born Haley Walsh, was born on September 9, 1994, and grew up in the Boston area of Massachusetts. She holds American nationality and comes from a close-knit family that supported her academic and personal pursuits from an early age.
Haley pursued higher education at Michigan State University, where she studied journalism and political science before graduating in 2016. Her college years overlapped with the early stages of her relationship with Pete Alonso, since the couple had already started dating a year before she began her studies in East Lansing.
Long before she became a recognizable name in MLB circles, Haley built a foundation for herself through her education and early career interests. Friends and family describe her as grounded and private, someone who has managed to stay out of the spotlight even as her husband’s career grew into one of the most talked-about stories in baseball. Today, she is best known as Pete Alonso’s wife, though her own work with the Alonso Foundation gives her an identity well beyond that title.
Haley Alonso’s Career & Professional Life
Professionally, Haley Alonso is the co-owner and co-founder of the Alonso Foundation, a charitable organization she runs alongside her husband. The foundation focuses on causes including hurricane relief, support for veterans, and youth programs, organizing community events such as youth baseball clinics and comedy nights to raise funds.
Her journalism and political science background from Michigan State gave her a strong communication foundation, which she has used to help manage the foundation’s public outreach and community partnerships. Haley is also known as an animal lover; she and Pete treat their dog, Brody, as part of the family, and they have supported animal rescue causes together.
Haley Alonso’s net worth is not publicly disclosed, as she has kept her personal finances private, separate from her husband’s well-documented baseball earnings. What is clear is that her role running the Alonso Foundation, combined with her steady presence supporting Pete throughout his MLB career, has made her an influential figure within the baseball community, even without seeking the spotlight herself.
How Did Pete Alonso and Haley Meet?
Pete Alonso and Haley met in the summer of 2015, when Pete was playing in the Cape Cod Baseball League, a well-known summer league for top college players. At the time, Pete was on his way to becoming a standout at the University of Florida, while Haley was preparing to start her studies at Michigan State University.
Because the two attended colleges in different states, they spent much of their early relationship long-distance. Rather than pulling them apart, the distance seemed to strengthen their bond, and the couple made a consistent effort to stay connected through Pete’s college baseball seasons and Haley’s university years.
Their relationship continued to grow steadily even as Pete’s baseball career took off after the New York Mets drafted him in 2016. In November 2018, Pete proposed, and the couple got engaged. By that point, they had already been together for more than three years, having built their relationship on a foundation of patience and long-distance commitment during their college days. The engagement marked the start of a new chapter that would eventually lead them to the altar three years later.
Marriage & Wedding Details
Pete Alonso and Haley Alonso got married on November 12, 2021, at Sacred Heart Catholic Church in Tampa, Florida. The wedding came almost exactly three years after their 2018 engagement and roughly six years after they first met on Cape Cod.
Pete has publicly called their wedding day one of the best days of his life, sharing throwback photos and heartfelt messages on their anniversaries. Haley has done the same, posting collages from the ceremony each November to mark the occasion. The couple has celebrated multiple wedding anniversaries together since 2021, often sharing glimpses of the day on social media, including sweet captions thanking each other for their years together.

Following Teddy’s birth, Haley shared an emotional post with a photo of their newborn overlooking the Manhattan skyline, writing about the night they welcomed their son into the world. Pete later explained that he chose jersey number 25 with the Baltimore Orioles specifically to honor his son’s 2025 birth year, calling it a special way to mark fatherhood.
