Matt Iseman has spent years cheering on competitors as the host of American Ninja Warrior, but his own life has had a pretty special love story happening away from the obstacle course.
The television host is married to Britton All, a criminal defense attorney who also has a creative side as a stand-up comedian. The couple’s relationship became public in 2022, they got engaged in January 2024 and married later that year in Denver, Colorado.
Their relationship has since entered another exciting chapter. Iseman and All welcomed their first child together, a son named James McIntosh Iseman, in December 2025. The couple affectionately calls him “Big Mac.”
For Iseman, the relationship represents a major personal milestone. He has openly spoken about how lucky he feels to have found All, and his social media posts about her have often mixed genuine affection with his trademark humor.
From a memorable proposal in Austria to a wedding filled with dancing and a new baby at home, here is everything to know about Matt Iseman’s wife, Britton All.
Who Is Matt Iseman’s Wife?
Matt Iseman is married to Britton All, a criminal defense attorney based in Los Angeles.
All has built her own professional career outside of Iseman’s television work. She works in criminal defense and has also pursued stand-up comedy, giving her and her husband another creative interest to share.
Iseman has described his wife as having a big personality, and he has joked about the fact that both of them essentially make a living by talking.
That makes their relationship an interesting combination. Iseman is a television host and comedian, while All spends her professional days working in law and has also stepped onto a comedy stage.
Her age has not been publicly established in the information provided.
All is also active on social media, where she has shared photographs from trips, outings and special moments with Iseman.
When Did Matt Iseman and Britton All Start Dating?
The exact beginning of their relationship has not been publicly confirmed.
However, All shared her first known Instagram photograph with Iseman in September 2022, when the pair appeared together at the Daytime Beauty Awards.
That gives a public starting point for their relationship, even though they may have known each other before that.
The couple also attended a charity event in October 2022, where Iseman was honored with the Mary Brown Stephenson Award from Gateway for Cancer Research.
All celebrated her partner’s achievement and described herself as proud of him.
Their relationship continued to appear in social media posts over the next year.
They were photographed together at a football game at SoFi Stadium, attended holiday gatherings and appeared at other events as a couple.
By the end of 2023, they had clearly become a regular part of each other’s lives.
Matt Iseman Proposed in Austria
Iseman proposed to All in January 2024 during a trip to Austria.
The proposal took place at a pre-party connected to the Hahnenkamm Races, a major skiing event in the Kitzbühel area.
It was not a quiet proposal in a private room.
Instead, Iseman made the moment a memorable public celebration, with Arnold Schwarzenegger playing a role in the occasion.
Schwarzenegger and Iseman have a professional connection dating back to Iseman’s appearance on The New Celebrity Apprentice, which Schwarzenegger hosted.
During the event, Schwarzenegger was involved with a musical performance. Iseman brought All onstage and asked her to marry him.
She said yes.
The moment was met with cheers from the people around them.
Iseman later shared the engagement news on social media, joking that he had received an “awesome gift” from All with a little help from Schwarzenegger.
All also celebrated the proposal online, writing that Iseman had done it “BIG.”
It was certainly an engagement story that fit the personality of a television host who spends much of his career around big moments.
Their Wedding Took Place in Denver
The couple got married on September 1, 2024, in Denver, Colorado.
Iseman shared photographs from the wedding and told his followers that he and All spent their first day as newlyweds watching American Ninja Warrior together.
That small detail says quite a bit about their relationship. Even after the wedding celebrations were over, the show that has played such a major role in Iseman’s career was still part of their first day as husband and wife.
The wedding also marked the beginning of another chapter for the couple.
By that point, Iseman had already spoken warmly about All and how excited he was about their future together.
Matt Iseman Says He Feels Lucky to Have Found Her
Before the wedding, Iseman spoke about his relationship with All and made it clear that both of them felt fortunate to have found each other.
During an interview in June 2024, he described All as a criminal defense attorney with a big personality.
He also joked about their dancing skills and said he would happily share videos from their wedding so people could see their “Ninja” athleticism.
The humor continued when he joked about the possibility of having “Ninja babies.”
But beneath the jokes was a more serious message.
Iseman said that he and All both felt lucky to have found each other and were excited about spending the rest of their lives together.
That became a reality just a few months later when they married.
Britton All Is a Criminal Defense Attorney
All’s main professional career is in criminal defense.
While Iseman’s work is highly public, her legal career has a different rhythm. She works in the courtroom and deals with legal cases rather than television audiences.
Still, Iseman has pointed out the similarities between their personalities.
Both are comfortable speaking their minds, and both have careers that require strong communication skills.
Iseman has jokingly described the two of them as people who “run our mouths for a living.”
For a criminal defense attorney, being able to speak clearly and confidently is an important part of the profession. For Iseman, communication has been central to his work as a comedian and television host.
Their different careers therefore have an unexpected point of connection.
Britton All Is Also a Stand-Up Comedian
Law is not All’s only professional interest.
She has also performed stand-up comedy.
In early 2024, before her wedding to Iseman, All announced comedy performances in Hollywood and shared a clip from one of her sets.
Her move into comedy is particularly interesting because her husband has spent years working as a comedian himself.
Iseman has said that All is very funny and has even joked that she may be funnier than him.
In one of his posts about their growing family, he referred to her as “admittedly much funnier than I am,” while adding that his friends regularly remind him that the comparison may not be difficult.
The joke is very much in line with the playful way he talks about their relationship.
Rather than seeing comedy as something that belongs only to him, Iseman has encouraged All to explore her own voice on stage.
The Couple Welcomed a Son
The biggest change in their relationship came in December 2025, when Iseman and All welcomed their first child together.
Their son is named James McIntosh Iseman.
The couple affectionately calls him “Big Mac.”
The news was later shared publicly in February 2026, when Iseman introduced his son to his followers.
The arrival of their baby came after Iseman had already celebrated his first wedding anniversary with All and publicly shared his excitement about becoming a father.
In a heartfelt message to his wife, Iseman looked back on their relationship and celebrated the future they were about to begin as parents.
He wrote that one of the things he loved about All was the kind of mother he believed she would become.
He also joked that life with her would never be boring.
That comment seems fitting for a couple whose relationship has already included a public proposal, comedy performances, a television career and plenty of playful moments.
Iseman Shared the Baby News With a Sweet Message
When Iseman announced that they were expecting a baby boy, he focused heavily on his relationship with All.
He told her that she made life better and said he loved her for being beautiful and smart, but also for being funnier than him.
Most importantly, he said he loved the kind of mother he believed she would be to their son.
The message offered a glimpse of how excited he was about starting a family with All.
It also showed how the couple’s relationship had developed.
They went from appearing together publicly in 2022 to an engagement in early 2024, a wedding later that year and parenthood in 2025.
That is a lot of change in just a few years.
Who Is Their Son “Big Mac”?
The couple’s son is James McIntosh Iseman, and they have given him the affectionate nickname “Big Mac.”
The nickname has a playful connection to his name and fits Iseman’s sense of humor.
The couple announced his arrival publicly in 2026, sharing photographs and introducing him as a new part of their family.
His birth also added another personal milestone to a period that has been professionally busy for Iseman.
Around the time he introduced his son publicly, Iseman was also preparing for his work connected with the 2026 Winter Olympics.
So his life was moving quickly on both the family and professional fronts.
Britton All and Matt Iseman’s Family Life
The couple is based in Los Angeles and has shared selected parts of their life together online.
All has posted photographs from trips and outings with Iseman, while he has also used social media to celebrate important moments in their relationship.
They do not appear to share every detail of their private life, but some major milestones have been public.
Those include their engagement, wedding, pregnancy announcement and the birth of their son.
For fans of American Ninja Warrior, these updates offer a different look at Iseman outside his familiar television role.
On the show, he is usually the energetic host cheering competitors through difficult obstacles.
At home, he is now a husband and father, with a young son who has quickly become an important part of his life.
Matt Iseman’s Career and Family Have Grown Together
Iseman’s relationship with All has developed alongside a major period in his professional career.
He remains closely associated with American Ninja Warrior, where his enthusiasm and commentary have made him a familiar part of the franchise.
He has also taken part in other television and entertainment projects.
In 2026, his professional schedule included work connected to NBC’s coverage of the Winter Olympics, adding another major broadcasting opportunity to his career.
At the same time, his personal life has changed considerably.
He went from being a longtime television host and comedian to becoming a husband and then a father.
All has been alongside him throughout that transition.
Her own career has continued as well, giving the couple a relationship in which both people have professional lives of their own.
Their Love Story Has a Playful Side
One of the most noticeable things about Iseman and All’s relationship is the amount of humor involved.
Their engagement was a theatrical moment in Austria.
Their wedding followed in Denver.
All has performed stand-up comedy, and Iseman has encouraged her to continue exploring that side of herself.
Even their conversations about parenthood have included jokes.
But behind all the humor, Iseman’s public comments have consistently emphasized affection and appreciation for his wife.
He has described feeling lucky to have found her and has spoken about being excited to spend his life with her.
Now they are doing exactly that while raising their son.
