Marshall Trenkmann is a name most people first encounter in the credits of a celebrity marriage announcement. He is the husband of Karla Souza, the Mexican actress millions know as Laurel Castillo from the hit series How to Get Away with Murder. But reducing Trenkmann to a spouse does him a disservice: he is a career banker and finance executive who built a serious professional life in two countries before he ever walked a red carpet.
For more than a decade, Trenkmann has been the quiet half of one of Hollywood’s most stable partnerships, raising three children with Souza while keeping his own public profile close to zero. He has no social media, gives no interviews, and appears in public almost exclusively at his wife’s side.
Here is everything that is actually known about Marshall Trenkmann: his Texas upbringing, his education, his banking career from Mexico City to Los Angeles, how he met Karla Souza, and the family life they have built together.

Who Is Marshall Trenkmann?
Marshall Trenkmann is an American banker and finance executive best known publicly as the husband of actress Karla Souza. While his wife’s face is familiar to television audiences around the world, Trenkmann himself is a private professional whose career has unfolded in the corporate world of credit analysis, risk management, and Latin American financial markets.
To be clear about one thing up front: despite occasional confusion online, Marshall Trenkmann has no connection to dancer Karina Smirnoff. He has been married to Karla Souza since May 2014, and the couple’s relationship is one of the entertainment industry’s quieter success stories.
Trenkmann’s biography is a study in contrasts with celebrity culture. Where fame rewards visibility, he has chosen discretion. Where Hollywood runs on self-promotion, he has built his reputation in boardrooms. Understanding him means looking past the red-carpet photos to the career underneath.
Early Life and Education
Marshall Trenkmann was born and raised in Texas. Details about his childhood, parents, and siblings have never been made public, and he has never discussed his family background in interviews. What is known is that he developed an early interest in business and finance, and that his academic path reflected a genuine intellectual curiosity about the wider world.
He attended Texas A&M University, where he earned both a bachelor’s degree and a master’s degree. Biographical sources most consistently report that his studies centered on Spanish and Latin American studies, a focus that would prove remarkably well suited to his later career. Some biographies also mention accounting or finance coursework, which aligns with the banking path he ultimately took.
The Latin American focus was not an accident or a passing interest. It became the foundation of his professional life, taking him to Mexico City for some of the most formative years of his career, and, indirectly, leading him to the woman he would marry.
A Banking Career in Two Countries
After graduating, Trenkmann entered the world of corporate and investment banking, specializing in credit analysis and risk management, the unglamorous but essential work of assessing whether large loans and deals make financial sense.
His first major posting took him to Mexico City, where he joined the CIB LATAM credit team, the Latin American corporate and investment banking division associated with Credit Suisse. He spent about two and a half years there, leading credit work focused on major Mexican corporations. It was demanding, high-stakes work in a foreign market, and it drew directly on the Spanish language skills and Latin American expertise he had built at Texas A&M.
He then returned to Texas, joining the CIB Oil and Gas credit team in Houston, where he worked on energy-sector financing. Later, he relocated to Los Angeles, where biographical sources report he rose to the position of credit risk director at JPMorgan, one of the world’s largest financial institutions. He has also served as a board member of the Center Theatre Group, the Los Angeles nonprofit behind the Ahmanson Theatre, the Mark Taper Forum, and the Kirk Douglas Theatre, a role that connects his financial expertise with the arts world his wife inhabits.
Meeting Karla Souza
The story of how Marshall Trenkmann met Karla Souza begins in Mexico. During his years working in Mexico City, he moved in the city’s professional and social circles, and through mutual connections he met Souza, who was then one of Mexico’s brightest young acting talents, already known for the hit film Nosotros los Nobles (We Are the Nobles).
By several accounts, the connection deepened through something more personal than show-business glamour. Souza has spoken in interviews about how the two bonded over shared family experiences with mental illness, finding in each other an unusual level of honesty and understanding. It was, by her telling, a relationship built on emotional candor rather than celebrity sparkle.
The couple got engaged in December 2013. They married in May 2014 in California, in ceremonies that blended private civil vows with a religious celebration. At the time, Souza’s American television career was about to explode: within months, she would debut as Laurel Castillo on Shonda Rhimes’s How to Get Away with Murder, the role that made her an international star.
Marriage and Family Life
Trenkmann and Souza’s marriage has now lasted more than a decade, a notable achievement in an industry not famous for longevity. Throughout it, they have maintained a deliberate balance: her career keeps her in the public eye, while he has remained firmly in the private world of finance and family.
The couple has three children together. Their daughter Gianna was born in April 2018, arriving just as Souza’s run on How to Get Away with Murder was entering its later seasons. Their son Luka was born on June 12, 2020, during the pandemic, an arrival Souza announced with a reflective message about hope and motherhood. A third child, daughter Giulia, was reported born in March 2024.
Souza occasionally shares glimpses of family life on her social media, where she has millions of followers, but Trenkmann himself stays out of the frame more often than not. When he does appear at premieres or award shows, it is as her plus-one, smiling politely and then stepping back into the background.
A Father of Three
Those who follow the couple’s rare public comments describe Trenkmann as a devoted, hands-on father. Balancing a demanding finance career with three young children and a wife whose acting schedule can take her across the globe is no small feat, but the family has made it work by keeping their home life in Los Angeles as normal and grounded as possible.
Souza has spoken about how parenthood changed them both, and about the conscious effort they make to raise their children with an awareness of the world beyond Hollywood. Trenkmann’s steady, non-industry presence is widely seen as an anchor for the family, the person who keeps everyday life running while his wife navigates the pressures of fame.
Life Away from the Spotlight
Marshall Trenkmann’s commitment to privacy is nearly total. He does not use Instagram, X, or Facebook, and he has never given a press interview about his life or marriage. In an age when even private citizens document their lives online, his absence is conspicuous and clearly deliberate.
This makes him a kindred spirit to other celebrity spouses who have chosen discretion over fame, like Todd Thompson, the ex-husband of Giada De Laurentiis, who likewise built a career outside the entertainment industry. The difference is that Trenkmann and Souza are still going strong, their partnership now well into its second decade.
His net worth is estimated by various celebrity biography sites at between five and seven million dollars, but these are rough guesses based on his banking career, not disclosed figures. Trenkmann has never commented on his finances, and any specific number should be treated with skepticism.
Bottom Line
Marshall Trenkmann’s story is a reminder that not everyone adjacent to fame wants a piece of it. A Texas banker who learned Spanish, built a career across two countries, and married one of television’s most recognizable actresses, he has spent more than a decade proving that the quietest role in a celebrity marriage can also be the most important one. While Karla Souza performs for millions, Marshall Trenkmann does the unglamorous, essential work of being the steady center of a family, and he seems perfectly content to stay out of the spotlight while doing it.
