Rob Lowe as Owen Strand

Rob Lowe plays Owen Strand, one of the central characters in 911: Lone Star. Owen is a New York firefighter who relocates to Texas and takes on a leadership role with the Austin 126.

Lowe’s performance gives Owen a combination of authority, confidence and vulnerability. His character is not simply presented as a first responder. The series also explores his relationships, family responsibilities and personal challenges.

Ronen Rubinstein as T.K. Strand

Ronen Rubinstein plays T.K. Strand, Owen’s son. T.K. is closely connected to both the emergency response team and the personal side of Owen’s storyline.

His relationship with Owen is an important part of the series, while his own career and relationships develop throughout the show. Rubinstein appeared as T.K. Strand throughout the series, with IMDb listing him in all 72 episodes.

T.K.’s character also connects several different storylines, making him one of the most recognizable members of the 911 Lone Star cast.

Jim Parrack as Judd Ryder

His character is particularly connected to Grace Ryder and their family storyline. Parrack is listed among the series’ principal stars and appeared in all 72 episodes according to IMDb.

Judd’s personality adds another layer to the firehouse dynamic, balancing professional experience with emotional and family focused storylines.

Gina Torres as Tommy Vega

Gina Torres plays Captain Tommy Vega, a paramedic who becomes a major member of the emergency response team.

Tommy brings leadership and experience to the series. Her character also has storylines outside emergency calls, allowing the show to explore the balance between a demanding career and family life.

IMDb’s episode credits identify Gina Torres as Tommy Vega alongside the main ensemble.

Torres’ presence expanded the show’s central cast and helped establish Tommy as an important figure within the Austin emergency response world.

Natacha Karam as Marjan Marwani

Natacha Karam plays Marjan Marwani, one of the firefighters at the Austin 126.

Marjan is portrayed as a confident and capable first responder who develops strong relationships with her colleagues. Her professional experiences form an important part of the show’s workplace storytelling.

Karam is listed among the principal cast members and is credited in all 72 episodes of the series.

Brian Michael Smith as Paul Strickland

Brian Michael Smith plays Paul Strickland, a firefighter at the 126.

Paul is known for his technical knowledge and calm approach during emergency situations. His character gives the show another perspective on teamwork and the challenges faced by first responders.

Smith is one of the show’s principal cast members and, like several other central performers, is credited across all 72 episodes.

Rafael L. Silva as Carlos Reyes

Rafael L. Silva plays Carlos Reyes, an Austin police officer.

Carlos’ role gives the series an important connection between the fire and police sides of emergency response. His personal storyline also becomes closely connected to T.K. Strand.

IMDb lists Silva as Carlos Reyes and credits him throughout the series.

The relationship between Carlos and T.K. became one of the show’s significant character relationships, helping expand the series beyond emergency calls.

Julian Works as Mateo Chavez

Julian Works plays Mateo Chavez, a firefighter associated with the 126.

Mateo adds a younger perspective to the team and develops professionally as the series progresses. His character is often involved in the group’s workplace relationships and emergency response storylines.

Works is listed among the principal cast and is credited across all 72 episodes.

Sierra McClain as Grace Ryder

Sierra McClain plays Grace Ryder, Judd Ryder’s wife and an important member of the show’s wider emergency response world.

Grace works as a 911 operator, giving viewers a perspective that is different from the firefighters and paramedics responding directly to emergencies.

Her relationship with Judd is another important part of the show’s character driven storytelling. IMDb episode credits identify Sierra McClain as Grace Ryder.

Brianna Baker as Nancy Gillian

Brianna Baker plays Nancy Gillian, a paramedic connected to the 126.

Nancy becomes part of the show’s larger emergency response ensemble and works alongside several of the principal characters.

Her role helps broaden the team beyond the most recognizable leads and gives the series additional opportunities to explore the everyday experiences of emergency workers. IMDb lists Baker as Nancy Gillian in the show’s cast credits.

Other Important Cast Members

The 911 Lone Star cast includes many supporting performers in addition to its main ensemble. The show’s episode credits include actors such as Benito Martinez as Gabriel Reyes and William Allen Young as Benjamin Williams.

The series also featured recurring and guest appearances that expanded the stories of the central characters. Because 911: Lone Star follows several interconnected groups, supporting characters can become important to individual story arcs without being part of every episode.

This large ensemble helped the show maintain multiple storylines at the same time.

What Made the 911 Lone Star Cast Stand Out?

One of the strongest features of the series was the way its ensemble worked together.

Instead of focusing on only one first responder, the show followed firefighters, paramedics, police officers and dispatchers. This allowed different characters to approach the same emergency from different professional perspectives.

The cast also supported the show’s balance between workplace drama and personal storytelling. Emergency calls provided the action, while relationships and family situations gave the characters additional depth.

That combination helped distinguish 911: Lone Star from a straightforward procedural series.

911 Lone Star Cast and Character Connections

The characters are closely connected, which makes the ensemble particularly important.

Owen Strand and T.K. Strand provide the central father and son connection. Judd and Grace Ryder form another major family relationship. T.K. and Carlos Reyes connect the firefighter and police sides of the story.

Meanwhile, characters such as Marjan, Paul, Mateo and Nancy contribute to the professional environment surrounding the 126.

These relationships allow individual storylines to overlap rather than existing separately.

Is 911 Lone Star Based on the Original 911?

911: Lone Star is a spin off of 911. The series moves the primary setting to Austin, Texas, while maintaining the broader focus on first responders and emergency situations.

The show was created by Ryan Murphy, Brad Falchuk and Tim Minear. IMDb identifies those three as the creators of the series.

The connection between the two shows also allowed the Lone Star series to exist within the wider 911 television universe.

How Many Seasons Did 911: Lone Star Have?

911: Lone Star ran from 2020 through 2025. IMDb lists the series as a 2020 to 2025 television series and records 72 episodes.

The show’s five season run gave its main characters considerable time to develop. This is one reason searches for the 911 Lone Star cast often include questions about both the actors and the characters they played.
