Diane Plese is Canadian and has Croatian family roots. She was born in Toronto, Canada, and grew up in a family whose parents had immigrated from Croatia. Her connection to American television comes through her former husband, Robert Herjavec, rather than a documented American birthplace or upbringing.
Plese is widely known as Herjavec’s former wife, but she also had her own professional career in optometry. Her story includes work, marriage, and raising three children, with much of that life unfolding away from the television spotlight.

Diane Plese’s Toronto Background
Toronto is central to Plese’s early life. Reporting identifies Parkdale as the neighborhood where she grew up, while accounts of her family describe her parents as Croatian immigrants.
This background helps explain the different descriptions readers may encounter. Calling her Canadian refers to her national background. Describing her as having Croatian roots refers to her family’s ancestry.
Those details belong together. Plese’s parents came from Croatia, while she was born and raised in Canada. Her family’s country of origin should therefore remain separate from her own birthplace.
Her childhood also provides a clearer starting point than the celebrity coverage through which many people discover her name. Before the television appearances and public interest surrounding her marriage, her story was already rooted in Toronto.
A Professional Career Before the Headlines
Plese worked as an optometrist and operated her own office during the early years of her marriage. Her professional background forms an important part of her biography, even though entertainment coverage often focuses on her former husband.
Ontario court records describe how her working life changed as their family grew. Following the birth of their first child in 1993, she began working part-time. She continued working reduced hours between subsequent maternity leaves.
Around 2003, she left the workforce to concentrate on managing the household and caring for the children. The court’s account describes this as an arrangement that allowed Herjavec to devote more attention to his businesses.
These details show that Plese contributed through both paid work and family responsibilities. They also explain why describing her solely through her former marriage leaves out a substantial part of her life.
Her historical career is documented. However, reliable public information does not establish whether she currently runs an optometry practice or continues seeing patients.
Her Marriage to Robert Herjavec
Plese married Robert Herjavec in 1990. They had three children together: Caprice, Skye, and Brendan.
Their marriage lasted until their separation in July 2014, followed by divorce in 2016. By then, Herjavec had become familiar to television audiences through business programs in Canada and the United States.
That public profile brought attention to the family. Readers who knew him through Shark Tank also began searching for information about his marriage, children, and former wife.
However, their biographies should remain distinct. Herjavec’s business activities and television appearances do not determine Plese’s nationality, professional status, or personal choices.
Why Readers May Assume She Is American
The confusion is understandable when someone first encounters Plese through American entertainment coverage. Shark Tank reaches a large U.S. audience, and articles about its investors often discuss their families alongside their television careers.
That association may explain why readers ask whether Plese is American. It does not provide evidence that she holds American citizenship.
A television connection, a family relationship, and citizenship are separate matters. The clearest information about Plese’s background remains her Toronto birthplace, Canadian upbringing, and Croatian ancestry.
The same care applies to descriptions such as “Canadian-American.” Without reliable confirmation of dual citizenship, that label goes further than the available evidence supports.
What Is Known About Her Citizenship?
American citizenship is not publicly verified for Diane Plese. Reliable accounts establish her Canadian background, but they do not confirm that she later became a U.S. citizen.
This leaves a straightforward answer to the main question: Diane Plese is Canadian, with Croatian family roots. Her former husband’s American television career helps explain the interest in her nationality, while her own background points back to Toronto.
