His father played college basketball at Purdue University and Auburn University before establishing a long coaching career, while his mother played college softball at Auburn.
The couple raised two sons, Braxton and Brooks, who both pursued basketball at the collegiate level.
According to their official Northwestern University and Rollins College athletic biographies, both brothers were coached by their father during their high school basketball careers.
The Barnhizer family’s sporting background has been an important factor in Brooks’ development from a young basketball player in Indiana to an NBA professional.
Brooks Barnhizer’s Father: Mark Barnhizer
Mark Barnhizer is Brooks Barnhizer’s father, a former college basketball player and highly experienced American high school basketball coach.
Originally from Lapel, Indiana, Mark developed an interest in basketball during his youth and became a standout player in high school.
He briefly attended Purdue University before transferring to Auburn University, where he played college basketball during the late 1970s.
His collegiate experience helped him develop an understanding of basketball fundamentals, competitive preparation, and team leadership.
Following his playing career, Mark entered coaching and spent more than four decades working with high school basketball programs.
His coaching career included positions at Eastern Greene High School, Elkhart Memorial, Hammond Gavit, Alma Bryant High School, and Lafayette Jefferson High School.
According to a March 2023 report published by the Lafayette Journal & Courier, Mark had recorded more than 530 victories during approximately 40 years as a high school basketball head coach.
His success established him as a respected figure in Indiana high school basketball.
How Mark Barnhizer Introduced Brooks to Basketball
Mark Barnhizer played a central role in introducing Brooks to basketball and developing his skills.
From an early age, Brooks and his older brother, Braxton, spent considerable time at basketball gyms while their father worked as a coach.
Rather than learning basketball exclusively through organized youth teams, the brothers grew up surrounded by competitive training environments.
Mark encouraged his sons to develop basketball fundamentals, including shooting, passing, defending, and understanding different situations on the court.
One of the family’s most memorable traditions involved early morning workouts.
According to a March 2024 feature published by FAU Owls Nest, Mark regularly took Brooks and Braxton to the gym for shooting sessions beginning around 6 a.m.
Brooks explained that the routine began when he was approximately in third grade.
Although waking up so early initially required adjustment, the sessions eventually became an important part of his daily life.
He credited the early morning practices with helping him develop a lasting passion for basketball.
The experience also contributed to his understanding of the discipline necessary to compete at a high level.
Mark Barnhizer’s Coaching Career at Lafayette Jefferson High School
Mark Barnhizer became head basketball coach at Lafayette Jefferson High School in Indiana in 2018.
The family had previously lived in Alabama, where Mark coached at Alma Bryant High School.
When Mark accepted the position at Lafayette Jefferson, the family relocated to Indiana.
Both of his sons subsequently played for the school’s basketball program.
Brooks attended Lafayette Jefferson during the final three years of his high school career, while Braxton also played for the Bronchos.
Under Mark’s guidance, the program enjoyed considerable success.
During the 2020–21 season, Lafayette Jefferson won its first sectional championship in 11 years.
Brooks became the team’s leading scorer and one of the highest-rated high school basketball players in Indiana.
His father emphasized defensive responsibility, consistency, and the importance of making contributions beyond scoring.
Those principles later became defining characteristics of Brooks’ playing style at Northwestern University and in the NBA.
In a February 2026 interview published by the Lafayette Journal & Courier, Mark expressed pride in his son’s professional development.
He highlighted Brooks’ ability to contribute to winning teams and his willingness to perform difficult tasks on the basketball court.
Mark Barnhizer’s Connection to Dusty May
One of the most interesting connections within the Barnhizer family’s basketball history involves college basketball coach Dusty May.
May, who later became head coach at Florida Atlantic University and the University of Michigan, played high school basketball for Mark Barnhizer at Eastern Greene High School in Indiana.
During the early 1990s, Mark developed a close relationship with May, encouraging him to work hard and develop his leadership abilities.
According to a 2024 interview published by Northwestern University Athletics, Mark regularly collected May from his home early in the morning so they could practice basketball before school.
Their relationship continued after May graduated and pursued his own coaching career.
When Brooks was growing up, the family remained in contact with May.
Brooks has described the former Eastern Greene player as someone who was almost like an older son to his father because of their longstanding relationship.
However, Dusty May is not Brooks Barnhizer’s biological brother or a member of his immediate family.
Their connection developed through Mark’s coaching career and the close relationship maintained between coach and former player.
In March 2024, Brooks discussed the family connection ahead of Northwestern’s NCAA Tournament game against May’s Florida Atlantic team.
He explained that the matchup was meaningful because it brought together two generations connected through his father’s coaching career.
Brooks Barnhizer’s Mother: Heidi Barnhizer
Heidi Barnhizer is Brooks Barnhizer’s mother and a former collegiate softball player at Auburn University.
Like her husband, Heidi has an athletic background that contributed to the family’s strong interest in competitive sports.
She attended Auburn University, where she participated in the softball program before raising her family.
Her sporting background is documented in the official athletic biographies of both Brooks at Northwestern University and Braxton at Rollins College.
Although Heidi did not pursue a professional basketball career, her experience as a college athlete gave her an understanding of the challenges associated with organized competition.
She supported both of her sons as they participated in basketball during childhood and high school.
The family moved several times because of Mark’s coaching career, including relocating from Indiana to Alabama and eventually returning to Indiana.
These changes required Brooks and Braxton to adjust to different schools, communities, and basketball programs.
Heidi remained involved in supporting the family throughout those transitions.
How Heidi Barnhizer Supported Brooks’ Basketball Career
Heidi Barnhizer has remained an important source of encouragement throughout Brooks’ basketball journey.
Her support became particularly visible in February 2026, when Brooks returned to Lafayette Jefferson High School during his first NBA All-Star break.
Rather than spending the break away from basketball, he chose to visit the school where he had developed into a prominent college prospect.
During the visit, Brooks attended a high school basketball game and spent time with former coaches, friends, and family members.
According to a February 19, 2026, report published by the Lafayette Journal & Courier, Heidi spoke positively about her son’s humility and continued connection to the community.
She explained that returning to Lafayette was especially meaningful because both Brooks and Braxton considered the city an important part of their lives.
Although the family had lived in several different locations, Lafayette had become a place they strongly identified with.
Heidi expressed pride in the way Brooks continued remembering the people and experiences that helped him reach the NBA.
Her comments demonstrated that the family valued his character and connection to his hometown alongside his professional achievements.

Braxton Barnhizer’s College Basketball Career

He began his collegiate basketball career with the Trolls during the 2020–21 season.

He also recorded a season-high 10 assists against Lynn University in February 2024.
What Does Braxton Barnhizer Do Now?
After his college basketball career, Braxton Barnhizer returned to Lafayette Jefferson High School and became involved in coaching.
His appointment as an assistant basketball coach was documented in the Lafayette School Corporation’s February 9, 2026, school board agenda.
That appointment reunited him with his father, Mark Barnhizer, who continued working with the school’s basketball program.
In February 2026, Brooks returned to Lafayette Jefferson during the NBA All-Star break and watched a game in which his father and brother were members of the coaching staff.
The occasion represented a continuation of the family’s basketball tradition.
Mark had previously coached both sons as high school players, while Braxton was now helping develop another generation of athletes.
Brooks’ presence at the game demonstrated his continuing connection to his family and the school where he developed into a college basketball prospect.
How Braxton Barnhizer Influenced Brooks’ Basketball Career
Braxton played an important role in Brooks’ early basketball development.
Because Braxton was older, he frequently provided a competitive challenge during their childhood.
The brothers regularly attended early morning basketball practices organized by their father.
Those sessions gave both players opportunities to improve their shooting, ball-handling, and decision-making.
Brooks also benefited from watching Braxton compete at the high school level.
When the family moved to Lafayette in 2018, both brothers became important members of the Lafayette Jefferson basketball program.
Their shared experiences strengthened the family’s connection to the school.
Although the brothers eventually attended different colleges, both pursued basketball seriously and remained connected through their shared sporting background.
Braxton’s decision to enter coaching in 2026 continued the family tradition established by their father.

His family’s commitment to basketball meant that he was accustomed to demanding training sessions and competitive environments.
