Marshall Trenkmann is a banking professional best known publicly as the husband of actress Karla Souza. His background includes work at J.P. Morgan in Houston, Mexico City, and Los Angeles. He also earned undergraduate and master’s degrees from Texas A&M University and became involved in theatre through a board appointment at Center Theatre Group.
His wife is widely recognized for playing Laurel Castillo in How to Get Away with Murder. They married in May 2014 and have three children: Gianna, Luka, and Giulia.
Much of the public interest in Marshall comes from his marriage, but his professional history provides another part of his story. The clearest information about him concerns his education, banking experience, theatre involvement, and the family milestones Karla has shared publicly.
Who Is Marshall Trenkmann?
Marshall Trenkmann has a professional background in banking, particularly credit risk. A biography published when Center Theatre Group announced his board appointment in 2016 described his experience working with corporate clients at J.P. Morgan.
His career included positions in the United States and Mexico. The documented timeline begins in Houston, continues in Mexico City, and later places him in Los Angeles. These positions show the areas in which he worked without establishing his present employment.
Outside finance, his appointment to a theatre organization’s board gave him a connection to the arts. That involvement is separate from his wife’s acting work, although both appear in accounts of their public lives.
Marshall Trenkmann’s Education
Marshall Trenkmann earned undergraduate and master’s degrees from Texas A&M University. Both qualifications appear in his published professional biography, making his university education one of the better documented parts of his background.
Some online biographies say his undergraduate degree was in accounting. However, the stronger professional source does not name the subjects of either degree. His education can be described accurately without assigning him a particular field of study.
The same biography mentions an interest in Spanish and Latin American studies. This is relevant background given his later work in Mexico, but it does not establish a separate qualification or prove a particular level of language fluency.
Marshall Trenkmann’s Banking Career
Marshall Trenkmann joined J.P. Morgan in 2004. He spent the first eight years of his career with its oil and gas credit team in Houston. This places his early banking work within a specific industry rather than general personal financial advice.
He later spent approximately two and a half years leading the bank’s Latin American credit team in Mexico City. His professional biography says that role focused on Mexican corporations.
By December 2016, he was described as a credit risk director based in Los Angeles, managing the CCB West Diversified Portfolio. The biography also noted that he had been with J.P. Morgan for more than 12 years at that point.
This timeline corrects a confusing detail in some shorter profiles. The oil and gas credit team and the Latin American credit team were parts of his banking career at J.P. Morgan, rather than separate companies he joined before working there. These are historical positions and should not automatically be treated as his current role.
What His Banking Work Involved
Credit risk concerns the possibility that a borrower will not repay money as agreed. In corporate banking, the work generally involves considering a company’s financial position, its ability to meet payments, and the risks attached to lending.
Marshall’s documented positions involved corporate credit. His Houston role focused on the oil and gas sector, while his Mexico City position involved Mexican companies. Those descriptions identify the kinds of businesses connected to his work.
The Los Angeles biography placed him in a role managing a portfolio, meaning a collection of credit relationships or exposures. It did not name individual clients or describe specific lending decisions. His career can therefore be explained without suggesting access to confidential deals or claiming achievements that have not been documented.
Marshall Trenkmann’s Connection to Theatre
Center Theatre Group announced Marshall’s appointment to its board of directors in 2016. He was one of 11 new board members named that year, with the group drawing members from several professional backgrounds.
The organization is a nonprofit theatre company in Los Angeles. At the time of the announcement, its work included productions at the Ahmanson Theatre, Mark Taper Forum, and Kirk Douglas Theatre, alongside education and community programs.
A board position is different from an acting, directing, or producing credit. His appointment establishes an involvement with the organization’s leadership, but it does not prove that he made films or performed onstage. It also should not be described as a current appointment without newer confirmation.
Who Is Karla Souza?
Karla Souza is a Mexican actress whose work in television and film brought wider public attention to Marshall. For many English speaking viewers, she is best known as Laurel Castillo in the ABC drama How to Get Away with Murder.
Laurel is a law student in the series, which stars Viola Davis. Some online biographies mistakenly call Souza’s character Lauren Castillo. Laurel is the correct name and an important detail when explaining why the actress is famous.
Souza also appeared in the television comedy Home Economics. Her acting career is separate from Marshall’s banking background, even though public coverage often brings their professional and family lives together.
Her interviews and family announcements provide much of the direct information available about their relationship. When she describes his gestures or support, those accounts should be understood as her own statements about their life together.
Marshall Trenkmann’s Marriage

Marshall Trenkmann and Karla married in May 2014. Reports agree on the month and year, although descriptions of the wedding location differ. Their marriage can be covered clearly without choosing an uncertain venue or adding details about guests and celebrations.
In a 2015 interview, Karla spoke about small gestures that made her feel appreciated. She described Marshall Trenkmann sharing articles connected to their conversations, including discussions about Latino culture. She also said he would leave affectionate notes in her bag.
These examples provide a more specific account than simply calling their marriage perfect or claiming to know how they manage every difficulty. They show what Karla chose to say about him at that time.
She thanked him again when announcing their third child in March 2024. In that announcement, she described his support during a long labor. Her comments offer a dated example of his involvement in an important family event without revealing every part of their private relationship.
Their Three Children
Marshall Trenkmann and Karla have two daughters and one son. Older biographies list only two children because they were published before the arrival of their youngest daughter. The family information needs to include all three: Gianna, Luka, and Giulia.
Their eldest daughter, Gianna, was born in April 2018. Karla announced her arrival after keeping the pregnancy out of the public eye. Different websites give different exact birthdays, so the supported month and year provide a clearer account.
Their son, Luka, was born in June 2020. His arrival made them parents of two, which explains the family descriptions in articles published in 2021 and 2022. Those articles were not necessarily wrong about the number of children at the time, but they are now incomplete.
Their younger daughter, Giulia, arrived in March 2024. Karla announced the birth on March 15 and shared photographs from the hospital. The announcement date should not automatically be used as Giulia’s exact birthday.
His Life Outside Work
Marshall’s public profile is smaller than his wife’s. Most widely available coverage focuses on his professional biography, their marriage, and family events that Karla has discussed or shared.
One personal interest mentioned in his 2016 biography was fishing while traveling. This is a documented detail, but it does not establish where he travels today or how he spends his regular free time.
Questions about his age, net worth, and social media accounts often appear in online profiles. The research used here does not firmly establish his exact birthday or finances. An older claim that he has no social media accounts also should not be treated as proof that no accounts exist.
Final Thoughts
Marshall Trenkmann’s documented background includes university study at Texas A&M, corporate credit work at J.P. Morgan, and a board appointment at Center Theatre Group. His career history connects him with finance and the arts.
His marriage to Karla Souza explains much of the public interest in him. Together, they have three children, and the family milestones she has shared provide a limited but useful account of their life beyond work.
