Sadie Sink Parents: Inside the Stranger Things Star’s Close-Knit Texas Family

Sadie Sink’s parents are Lori Sink and Casey Sink, two educators who helped their daughter pursue acting long before she became internationally recognised for playing Max Mayfield in Netflix’s Stranger Things. Her mother worked as a mathematics teacher, while her father built a career in teaching and football coaching. Although neither parent came from the entertainment industry, they recognised Sadie’s interest in performing and made important family decisions that helped turn her childhood passion into a professional career.

Born on April 16, 2002, in Brenham, Texas, Sadie grew up in a household where sports, education and family activities were part of everyday life. She was one of five children, and her early interest in musical theatre developed alongside her brother Mitchell. Her parents eventually relocated the family closer to New York so their children could pursue acting opportunities. That decision became an important turning point in Sadie’s journey from community theatre to Broadway and Hollywood.

Who Are Sadie Sink’s Parents?

Sadie Sink’s mother is Lori Sink, formerly Lori Baughman, and her father is Casey Sink. Both worked in education and raised their five children in Brenham, a small Texas city located between Houston and Austin.

The Sink household was originally more connected to sports than entertainment. Casey worked as a football coach, and the children grew up around school activities and athletic competitions. However, Sadie and her brother Mitchell developed a strong interest in singing, acting and musical theatre.

Their parents encouraged them to explore those interests rather than insisting they follow a sporting path. What began with performances at home eventually developed into acting classes and community theatre productions.

Lori and Casey’s support became especially important when Sadie started receiving opportunities outside Texas. The family eventually moved to the New York area, allowing her to participate in professional theatre while continuing her education.

Their willingness to adjust family life around their children’s interests helped establish the foundation for Sadie’s career.

Sadie Sink’s Mother Lori Sink

Lori Sink is Sadie’s mother and one of the earliest people to recognise her interest in acting. Before her daughter became famous, Lori worked as a mathematics teacher.

Her background was far removed from Hollywood, but she noticed that Sadie and Mitchell enjoyed performing from a young age. The siblings frequently recreated scenes from High School Musical and watched recordings of Broadway performances.

Instead of treating their enthusiasm as a passing childhood interest, Lori encouraged them to take it seriously. When Sadie was around seven years old, she enrolled her in acting classes in Houston.

The decision introduced Sadie to structured theatre training and gave her opportunities to perform outside the family home. She subsequently participated in local productions, developing confidence and experience in front of audiences.

Lori remained closely involved as Sadie’s acting opportunities increased. She also helped manage the practical challenges of combining professional performances with childhood education.

Her encouragement played an important role in helping Sadie discover that acting could become more than a hobby.

Sadie Sink’s Father Casey Sink

Casey Sink is Sadie’s father and a longtime educator with a background in football coaching. He previously worked in Texas before continuing his teaching and coaching career in New Jersey.

Casey has taught mathematics, including subjects such as algebra and geometry. He has also coached high school football, making sports an important part of the family’s early environment.

Despite his athletic background, Casey supported Sadie’s interest in performing arts. His daughter preferred acting and musical theatre to the sporting activities that were familiar within the household.

His support became particularly significant when Sadie started securing professional opportunities. Moving away from Texas required changes to employment, schooling and everyday family arrangements.

Casey eventually joined the family in the New York area after Sadie’s Broadway career began developing.

His experience as a teacher also helped the family maintain an emphasis on education while Sadie worked professionally.

Unlike his daughter, Casey has generally maintained a private public profile and is primarily known through his teaching career and family connections.

Sadie Sink’s Childhood in Brenham, Texas

Sadie Elizabeth Sink grew up in Brenham, Texas, where she spent her early childhood surrounded by her parents and four siblings.

Her family enjoyed sports, but Sadie developed a particular fascination with musical theatre. She and Mitchell would perform scenes from their favourite productions and imagine themselves appearing on stage.

Their enthusiasm eventually encouraged Lori to arrange acting lessons. Sadie began participating in community theatre at approximately seven years old.

One of her early productions was The Best Christmas Pageant Ever. She later appeared in a local production of The Secret Garden, gaining valuable experience with rehearsals and memorising dialogue.

These performances helped her understand the commitment required for acting.

Her childhood was not spent growing up within a famous Hollywood family. Instead, she developed her abilities through local opportunities and support from parents who were willing to encourage an unfamiliar career path.

That background remains an important part of her personal story.

Why Did Sadie Sink’s Parents Move to New Jersey?

One of the biggest decisions Lori and Casey made involved relocating their family to support Sadie’s developing theatre career.

In 2012, Sadie became involved in the Broadway production of Annie. The opportunity required her to spend considerable time near New York City.

Travelling regularly from Texas was not practical for a young performer with professional rehearsal and performance commitments.

The family therefore moved closer to the theatre industry, eventually settling in Summit, New Jersey.

The relocation affected more than Sadie. Her parents had to manage employment changes, and her siblings also experienced a different living environment.

Casey continued working in education and coaching, while Lori helped support the children’s schooling and acting schedules.

Sadie was homeschooled for part of her early career, allowing her to balance academic responsibilities with professional performances.

The family’s decision demonstrated how seriously her parents took her ambitions, even though they had no established connections within the entertainment industry.

How Many Siblings Does Sadie Sink Have?

Sadie Sink has four siblings, including three older brothers and one younger sister.

Her brothers are Spencer, Caleb and Mitchell Sink, while her younger sister is Jacey Sink.

Mitchell shares Sadie’s interest in acting and musical theatre. The two were particularly close during childhood and frequently performed together at home.

Their shared enthusiasm helped introduce Sadie to Broadway productions and the wider performing arts.

Mitchell later pursued acting professionally and appeared in television and film projects.

Her other brothers, Caleb and Spencer, have followed different professional interests. Caleb has worked in sports-related roles, while Spencer pursued a legal career.

Jacey, the youngest member of the family, has also appeared on screen. She portrayed younger versions of Sadie’s characters in Stranger Things and The Whale.

Despite their different career paths, the siblings have maintained close family connections.

Sadie has spoken warmly about Mitchell, describing their relationship as particularly important in her life.

How Sadie Sink’s Parents Helped Shape Her Acting Career

Sadie Sink’s acting career began with community theatre, but her parents’ support helped her reach much larger audiences.

After gaining experience in local productions, she joined the Broadway revival of Annie. The opportunity introduced her to professional theatre while she was still a child.

She later appeared in The Audience, portraying a young Queen Elizabeth II alongside Helen Mirren.

Her transition into television included appearances in American Odyssey before she joined Stranger Things as Max Mayfield during its second season.

The role transformed her career. Max became one of the series’ most recognisable characters, particularly through the emotional storyline featured in the fourth season.

Sadie subsequently expanded her film work with projects including The Whale and Taylor Swift’s All Too Well: The Short Film.

Her performance in the Broadway play John Proctor Is the Villain earned her a Tony Award nomination in 2025, marking another important achievement in her stage career.

She has also continued exploring major film opportunities, including a role in the Marvel film Spider-Man: Brand New Day.

Throughout these developments, Sadie has remained relatively private about her personal life.

Her close relationship with her family has helped her maintain a connection to the upbringing she experienced before becoming famous.

How Lori and Casey Sink Kept Their Daughter Grounded

Growing up in the entertainment industry can create unusual pressures, particularly for actors who become famous as children.

Sadie’s parents approached her career while continuing to emphasise education and family relationships.

Neither Lori nor Casey was a professional actor, which meant Sadie’s childhood was not originally built around Hollywood expectations.

Their support focused on giving her opportunities to develop her abilities while maintaining a connection to ordinary family life.

Sadie has spoken about the importance of her siblings and the trust she shares with them.

Her relationship with Mitchell has been especially meaningful because they discovered their interest in performing together.

Even after achieving international recognition, she has continued to value privacy and time away from public attention.

Her parents’ decision to support her career without making fame the centre of family life helped create a relatively stable environment.
