Jack Iscaro Bio
Jack Iscaro is an American rugby union player who represents the United States men’s national team, known as the USA Eagles, and plays his club rugby for Top 14 side Stade Français in France. A loosehead prop by trade, he has built a reputation as a dependable scrummager and a regular starter at the highest levels of the sport. Born in Germany and raised in the United States, Iscaro combines an American upbringing with a transatlantic professional career that now takes him into one of Europe’s most demanding leagues.
Early Life and Background
Jack Iscaro was born on 4 August 1997 in Germany before his family relocated to the United States. He grew up in Olney, Maryland, a community in the Washington, D.C. metro area, where he spent the majority of his childhood and adolescent years. This blend of European birthplace and American upbringing helped shape his identity as a player who would later pursue opportunities on both sides of the Atlantic.
Iscaro attended Gonzaga College High School in Washington, D.C., where he began developing the physical profile and rugby skills that would later define his career. Standing 185 cm tall and competing at around 123 kg, his size made him a natural fit for the demands of the front row, the traditional home of the largest and strongest players on a rugby pitch. After completing his secondary education, he continued his academic and athletic career at the University of California, Berkeley, one of the most storied rugby programs in American collegiate sport.
Path to Rugby
At the University of California, Berkeley, Iscaro became part of a proud rugby tradition that has produced numerous international players. He won two Collegiate Championships with the program in 2018 and 2019, contributing as a forward during one of the most successful stretches in Cal rugby’s modern history. These titles marked his first major team accomplishments and confirmed his readiness for senior-level rugby.
Following his collegiate success, Iscaro took a step toward professional rugby by signing a training contract with Glasgow Warriors of the United Rugby Championship in Scotland. Although his time with the Scottish club was brief, it exposed him to a full-time professional environment and gave him a taste of European rugby. He then turned his attention back to the United States, where a new domestic league was reshaping the professional pathway for American players.
Jack Iscaro Career
Early Career (2021–2022)
Iscaro signed for Old Glory DC ahead of the 2020 Major League Rugby season, but a delay caused by injury kept him off the pitch until the 2021 season, when he finally made his MLR debut. The Washington, D.C.-based franchise provided an ideal environment for the young prop to adjust to the pace and physicality of professional rugby in North America. Within a short period, he established himself as a regular in the front row.
During his first two seasons with Old Glory DC, Iscaro developed into a reliable starter and earned recognition as one of the league’s top props. His scrummaging strength and work rate around the field made him a central figure in the team’s forward pack. By the end of 2022, he had also broken into the United States national team setup, completing his transition from promising prospect to established professional.
Major League Rugby Breakthrough (2022–2025)
From 2022 to 2025, Iscaro served as a stalwart for Old Glory DC, starting 56 of his 76 appearances across his Major League Rugby career. He became a regular first-choice loosehead prop for the franchise, anchoring the scrum and providing a steady platform for the team’s attacking play. His consistency and durability helped him stand out as one of the most reliable forwards in the league.
Iscaro’s performances at club level were matched by his growing reputation on the national stage. He was a four-time All-MLR selection, a recognition that underscored his sustained excellence in the competition, and was named in the All-MLR First XV twice, in 2023 and 2025. These honors confirmed his status among the premier props in North American rugby and contributed to his continued selection for the USA Eagles.
Stade Français Era (2025–Present)
In October 2025, Iscaro signed a short-term contract with French Top 14 club Stade Français as a medical joker, joining the Paris-based side to provide cover in the front row. The opportunity allowed him to test himself in one of the most competitive domestic leagues in world rugby, where he quickly impressed coaches and teammates. His scrummaging pedigree translated effectively to the demands of the French game.
Following his initial months with the club during the 2025–2026 campaign, Stade Français re-signed Iscaro in December 2025 to a deal that runs through June 2027. The three-year agreement marked a significant transition in his professional career, moving him from Major League Rugby into the European top flight on a long-term basis. The extension solidified his position as a primary representative of United States rugby in one of the sport’s most demanding leagues.
Driving Style and Strengths
Iscaro is recognized for his scrummaging power, an essential trait for any loosehead prop, and for his consistency in the set piece. His size and technique make him a strong contributor in tight exchanges, while his endurance allows him to remain effective across the full eighty minutes.

Notable Events and Milestones
Among Iscaro’s signature achievements are his two Collegiate Championships with the University of California, Berkeley in 2018 and 2019, his MLR debut with Old Glory DC in 2021, and his All-MLR First XV selections in 2023 and 2025.
