Sam Hauser Bio
Samuel David Hauser is an American professional basketball player for the Boston Celtics of the National Basketball Association (NBA). Standing 6 ft 7 in (2.01 m) and listed at 217 lb (98 kg), he plays the small forward position and is recognized for his elite perimeter shooting. He helped the Boston Celtics win the 2024 NBA Finals and remains a key rotation piece for the franchise. His professional career began in 2021 after going undrafted, and he has since developed into one of the league’s most reliable three-point specialists.
Early Life and Background
Samuel David Hauser was born on December 8, 1997, in Green Bay, Wisconsin, USA. He grew up in a deeply sports-oriented family and attended Stevens Point Area Senior High School (SPASH) in Stevens Point, Wisconsin, where he lettered in basketball, golf, and football. His father, Dave, served as an assistant basketball coach, giving Sam an early education in the fundamentals of the game. His younger brother, Joey, was one of his teammates for his final two prep seasons, while his sister, Nicole Hauser, went on to play volleyball at Southern Connecticut.
As a junior at SPASH, Hauser averaged 18 points, 7.5 rebounds, and 3.3 assists per game, leading the state with a 50.6 percent three-point shooting mark. He guided his team to a 27–1 record and the Wisconsin Interscholastic Athletic Association Division 1 state championship, scoring 25 points in the title game against Germantown. In his senior year, he helped SPASH complete an undefeated season and capture a second straight Division 1 crown, posting 18.2 points, 6.7 rebounds, four assists, and 3.1 blocks per game.
His senior performance earned him the Wisconsin Gatorade Player of the Year award and a share of the Wisconsin Mr. Basketball honor alongside teammate Trevor Anderson. On May 17, 2015, Hauser committed to playing college basketball for Marquette, choosing the Golden Eagles over Virginia, Iowa State, and Creighton.
Path to Basketball
Hauser made his Marquette debut on November 11, 2016, scoring 14 points in 19 minutes off the bench in a 95–71 win over Vanderbilt, and was named Big East Conference Freshman of the Week. He recorded 19 points in a victory over Georgia on December 4, 2016, and matched that mark twice more by mid-February, helping Marquette set a program record for three-pointers in a single season. As a freshman, he averaged 8.8 points, five rebounds, and 1.3 assists per game, shooting 45.3 percent from beyond the arc.
His sophomore year featured a 30-point, nine-rebound, four-assist effort in an overtime win over Eastern Illinois on November 27, 2017, and a career-high seven three-pointers against American on December 21. He matched his 30-point high in a loss to Butler on January 12, 2018, and finished the year averaging 14.1 points, 5.7 rebounds, and 2.9 assists. In his junior season, he was joined at Marquette by his brother, Joey, scored a career-high 31 points against Georgetown on January 15, 2019, and was named to the All-Big East second team after averaging 14.9 points, 7.2 rebounds, and 2.4 assists.
Following that junior campaign, Hauser announced his decision to transfer in search of a better fit. On May 28, 2019, he committed to the Virginia Cavaliers, and after sitting out a year under NCAA transfer rules, he debuted on November 25, 2020, with 19 points in a win over Towson. As a senior he averaged 16 points, 6.8 rebounds, and 1.8 assists, shooting 50 percent from the field, 42 percent from three, and 90 percent from the free throw line. He fell just .004 short in free throw percentage from officially qualifying for the 50–40–90 club. On March 25, 2021, he declared for the 2021 NBA draft.
Sam Hauser Career
Early Career (2021–2022)
After going undrafted in the 2021 NBA draft, Hauser signed a two-way contract with the Boston Celtics on August 13, 2021, splitting his time between Boston and their G League affiliate, the Maine Celtics. He made his NBA debut on November 20, 2021, in a 111–105 victory over the Oklahoma City Thunder. On February 11, 2022, his two-way deal was converted into a standard NBA contract, signaling the franchise’s growing confidence in his shooting touch.
The Celtics reached the 2022 NBA Finals that season but lost to the Golden State Warriors in six games despite holding a 2–1 lead. Although Hauser was a developmental piece in that playoff run, the experience laid the groundwork for a larger role going forward.
Boston Celtics Breakthrough (2022–2024)
On July 3, 2022, Hauser re-signed with the Celtics on a three-year, $6 million contract. He delivered several clutch performances, including a game-tying three-pointer with three seconds left against the Milwaukee Bucks on February 14, 2023, and a then career-high 26 points in a 121–102 victory over the Toronto Raptors on April 7, 2023. During the 2023–24 regular season he contributed five dunks in eighteen games, earning him the popular nickname “Slam Hauser” after a 126–97 win over the Utah Jazz on January 5, 2024.
On March 17, 2024, Hauser erupted for a then career-high 30 points on a career-high 10 three-pointers in a 130–104 win over the Washington Wizards. He then helped the Celtics win the 2024 NBA Finals, draining 11 three-pointers across the series as Boston defeated the Dallas Mavericks in five games. The championship run cemented his reputation as a marksman who could thrive on the league’s biggest stage.
Boston Celtics Era (2024–Present)
On July 21, 2024, the Celtics rewarded Hauser with a four-year, $45 million contract extension that runs through the 2027–28 season. He continued to expand his offensive game, scoring a career-high 33 points, including nine three-pointers, in a 114–108 victory over the Utah Jazz on March 10, 2025. In that same game, he made seven three-pointers in the third quarter, setting a Celtics franchise record for most threes in a single quarter and becoming only the eighteenth player in NBA history to hit seven or more threes in one period.
He has remained a rotation regular in Boston’s three-point-heavy offense, providing spacing alongside stars like Jayson Tatum and Jaylen Brown. His blend of efficiency, movement shooting, and size has made him a favorite of head coach Joe Mazzulla.
Driving Style and Strengths
Hauser’s game is built around his perimeter shooting. He excels as a catch-and-shoot threat, runs crisp off-ball screens, and stretches defenses with his 6 ft 7 in frame. While he is not a primary creator, his rebounding, smart cuts, and surprising finishing at the rim have made him a well-rounded complementary piece. His rapid development in transition three-point shooting and ability to knock down contested looks have turned him into one of Boston’s most reliable bench weapons.
Notable Events and Milestones
Among his signature achievements are the 2024 NBA championship, the franchise-record seven three-pointers in a single quarter, and his career-high 33-point performance against the Jazz. He also earned the “Slam Hauser” moniker for his unexpected athleticism, a 26-point outing versus the Raptors, and a game-tying triple against the Bucks. He joins an elite group as the eighteenth player in NBA history to sink seven or more three-pointers in one quarter.
Sam Hauser Career Wins
Sam Hauser has built his reputation primarily on shooting consistency and postseason success rather than volume scoring, and his most celebrated victory is the 2024 NBA Championship with the Boston Celtics.
Boston Celtics Highlights
Hauser’s Boston tenure has produced a championship ring, a contract extension, and multiple career-best scoring nights. His first major milestone as a Celtic came with the two-way contract conversion in February 2022, followed by appearances in the 2022 NBA Finals. His most recent standout moment was the 33-point, nine-three performance against the Utah Jazz in March 2025, a game that set a franchise record and underscored his growing offensive confidence. The 2024 title remains the defining achievement of his professional career to date.
Other Wins & Performances
Before turning pro, Hauser captured two Wisconsin Division 1 state championships at SPASH and earned Wisconsin Gatorade Player of the Year honors. In college, he was named to the All-Big East second team in 2019 and was a First-team All-ACC selection in 2021. He very nearly joined the 50–40–90 club at Virginia, a remarkable feat in itself given the narrow margin.
Sam Hauser Family
Family Background and Racing Lineage
Basketball runs deep in the Hauser family. His father, Dave, was an assistant basketball coach, and his younger brother, Joey, played alongside him at SPASH and at Marquette. His sister, Nicole Hauser, competed collegiately as a volleyball player at Southern Connecticut. The close-knit support system helped shape Sam’s competitive drive and fundamentally sound approach to the game.
Personal Life
Hauser maintains a relatively private personal life away from basketball. He is active on social media and is known for his calm, team-first demeanor in the Celtics locker room. His brother Joey’s career has remained a frequent topic of conversation among fans who follow the family’s basketball journey.
2025 Season Performance
The 2025 calendar year has been a breakout stretch for Hauser. His career-high 33-point, nine-three-point performance against the Utah Jazz on March 10, 2025, set a Celtics franchise record for most three-pointers in a quarter. The outburst also placed him among an elite list of NBA players to hit seven or more threes in a single period. The strong play has reinforced his standing as a key rotation piece in Boston’s championship defense.
Coming off the 2024 title, Hauser’s role in 2025 has remained consistent: provide spacing, knock down threes, and support stars Jayson Tatum and Jaylen Brown. His efficiency numbers have remained a strength, and his growing comfort attacking closeouts has added a new wrinkle to his offensive profile. Coach Joe Mazzulla has continued to rely on him in pivotal late-game situations, including the clutch triple against Milwaukee in 2023 that signaled his emergence as a closer.
With a four-year, $45 million extension secured, Hauser enters the heart of the 2025 season firmly entrenched in Boston’s plans. The Celtics remain championship contenders, and his ability to stretch defenses will be central to any deep playoff run. As the year progresses, his continued development as a shooter and secondary playmaker will be a critical storyline for the franchise.
