Meet Marshall Trenkmann, Karla Souza’s Husband of 12 Years

Marshall Trenkmann is a finance professional best known as the husband of How to Get Away with Murder actress Karla Souza. After meeting in Mexico, the couple became engaged in 2013, married in 2014 and went on to welcome three children: Gianna, Luka and Giulia.

While Souza built a career in front of the camera, her husband followed a very different path through banking and corporate finance. Their worlds may look different professionally, but their more than decade-long marriage, growing family and shared connection to Mexico have become central chapters in their story.

Profile Summary: Marshall Trenkmann

Texas Roots and Early Foundations

Before Mexico became the setting for both a major career chapter and his future romance, Trenkmann’s story began in Texas. Public accounts have long identified the finance professional with the state, though he has shared little publicly about his childhood or upbringing.

That low-key approach would follow him into adulthood. Even after marrying a successful actress, Trenkmann never developed the public-facing profile common among celebrity spouses, leaving his career and family milestones to tell much of his story.

Education and the Academic Path Into Global Finance

Before beginning his international finance career, Trenkmann reportedly studied accounting at Texas A&M University. Published profiles have also connected his college years with studies in Spanish and Latin American culture — interests that fit naturally with the professional path that later took him to Mexico.

Some biographies also credit him with graduate studies at Texas A&M, although detailed information about that degree is less clearly documented. His accounting background, however, became the foundation for a career centered on corporate credit and banking.

A Career in Banking: From Mexico to Los Angeles

Trenkmann’s career took an international turn when he moved to Mexico and worked in corporate credit, including reported work with CIB LATAM involving Mexican companies. The experience gave him a professional connection to Latin America — and ultimately placed him in the country where he would meet Souza.

His career later brought him back to Texas, where published accounts place him in Houston working in oil-and-gas credit. He subsequently moved to Los Angeles, bringing his finance career into the same city where Souza was pursuing an increasingly prominent acting career.

How Marshall Met and Fell for Actress Karla Souza

Mexico became personal as well as professional when Trenkmann met Souza while working there. Their connection grew into a committed relationship, and by late 2013, the couple had taken the next step and become engaged.

Souza later gave fans glimpses into why their relationship worked. Speaking publicly about her husband, the actress has emphasized the values and emotional understanding they shared — qualities that became especially meaningful when the two opened up to each other about difficult experiences within their families.

Marshall Trenkmann and Karla Souza’s 2014 Wedding

Months after their engagement, Trenkmann and Souza made it official in 2014. Reports have placed their wedding celebration in Tequesquitengo, Morelos, giving Mexico another important place in a love story that had already taken shape there.

The marriage arrived during a pivotal period for Souza professionally. That same year, American television audiences were introduced to her as Laurel Castillo on ABC’s How to Get Away with Murder, beginning a new chapter that would bring significantly more attention to the actress and her family.

Becoming Karla Souza’s Steady Partner Behind the Scenes

As Souza’s career grew in the United States, her husband remained a quieter presence beside her. The actress has occasionally opened up about the emotional foundation of their relationship, offering rare insight into a marriage that otherwise unfolds largely outside celebrity coverage.

During a 2020 appearance on Red Table Talk: The Estefans, Souza discussed mental-health struggles within her family and the understanding she found with Trenkmann. She explained that he could relate through experiences in his own family, creating space for conversations she had previously found difficult to have with partners.

Welcoming Three Children: Gianna, Luka and Giulia

Nearly four years after marrying, Souza and Trenkmann became parents with the arrival of their daughter Gianna in April 2018. Souza surprised followers on Instagram with the news after keeping her pregnancy largely out of public view.

Their son, Luka, followed in 2020. Then, in March 2024, the family grew once more when Souza welcomed daughter Giulia after what the actress described on Instagram as a 33-hour labor — a dramatic delivery during which Trenkmann remained by her side.

Navigating Fatherhood and a Private Family Life

With Gianna, Luka and Giulia, the couple’s story has gradually shifted from newlywed life to raising a family of five. Souza occasionally celebrates major family moments publicly, particularly births and meaningful milestones, while keeping much of her children’s everyday lives outside the spotlight.

Trenkmann takes an even quieter approach. Rather than turning fatherhood into a public identity, he appears primarily through the family moments Souza chooses to share, maintaining the understated presence that has characterized him throughout their marriage.

Connecting a Finance Career With Theater and the Arts

Banking may have shaped Trenkmann’s professional life, but his world has also intersected with the performing arts. Published profiles have connected him with Los Angeles’ Center Theatre Group, a nonprofit organization devoted to live theater and arts programming.

The connection creates an interesting meeting point between the couple’s careers. Souza built her name through acting, while her husband has approached the arts from outside the stage and screen — a contrast that reflects the different professional paths they have maintained throughout their marriage.

Staying Grounded Away From the Social Media Spotlight

As Souza connected with audiences through television, film and social media, Trenkmann largely avoided building a comparable public presence. More than a decade into their marriage, he remains considerably less visible online than his famous wife.

That difference has helped keep the spotlight centered on Souza’s work rather than turning their marriage into a celebrity brand. When fans do see Trenkmann, it is generally through moments connected to his wife and family rather than a public platform of his own.

Life Today: Marriage, Parenthood and a Low-Key Public Profile

More than a decade after their 2014 wedding, Souza and Trenkmann have moved through several defining chapters together — from their Mexico romance and her Hollywood breakthrough to becoming parents of three.

Their youngest daughter, Giulia, joined Gianna and Luka in 2024, beginning another chapter for the family of five. Trenkmann’s exact current professional role is less publicly documented than his earlier finance career, but his public story remains closely tied to banking, marriage and fatherhood.

Conclusion

Trenkmann entered the public conversation because of the woman he married, but his story has never followed a typical celebrity-spouse script. His career developed in finance rather than entertainment, while his relationship with Souza grew from their time in Mexico into a marriage now more than a decade strong.

Today, the couple’s three children — Gianna, Luka and Giulia — sit at the heart of that story. From career moves to marriage and parenthood, Trenkmann has remained the quieter half of a partnership built across two very different professional worlds.
