Diane Plese is a Canadian optometrist who became widely known through her marriage to businessman and television personality Robert Herjavec. Although her former husband has built a public career through entrepreneurship, technology, and television, Diane Plese has maintained a much quieter presence. Her professional background, family life, and connection to one of Canada’s best-known business figures have made her a subject of interest among people looking for information about her life.
Unlike Robert Herjavec, Diane Plese has generally stayed away from interviews, entertainment appearances, and regular media attention. As a result, several details about her personal life remain limited or are reported differently across online sources. Her exact date of birth, educational history, current residence, and personal financial position have not been reliably established through authoritative public records.
Who Is Diane Plese?
Diane Plese is a Canadian optometrist best known as the former wife of Robert Herjavec. She was born in 1959 in Parkdale, Toronto, Ontario, Canada, according to widely circulated biographical information. Her professional career is associated with optometry, a healthcare field focused on vision, eye health, and related services.
Her name became more recognizable after her relationship with Robert Herjavec, who gained prominence as a technology entrepreneur and television investor. Their marriage lasted approximately 24 years and resulted in three children.
Diane Plese has kept much of her life private. While her former husband has appeared in business programs and public events, she has not maintained the same level of media exposure. This difference has contributed to public curiosity about her career, family, and activities after the marriage ended.
There is limited independently verified information about Diane Plese’s life outside her professional background and relationship with Robert Herjavec. Therefore, some frequently repeated details about her should be treated as estimates rather than established facts.
Diane Plese Biography at a Glance
Diane Plese was born in 1959 in Parkdale, Toronto, Ontario, Canada. She is Canadian and is commonly described as having Croatian heritage. Reports state that her parents were Croatian immigrants, although detailed information about her family background has not been widely documented.
Her profession is optometry, and she is primarily known publicly because of her former marriage to Robert Herjavec. The couple married around 1990 and were together for approximately 24 years before their divorce.
Diane Plese is reported to have three children named Brendan, Skye, and Caprice. Her marital status is divorced. Reports frequently place her current residence in Toronto, Canada, but this has not been officially confirmed.
Her exact birth date is not publicly known. Based on her reported birth year of 1959, Diane Plese would be approximately 66 or 67 years old in 2026, depending on when her birthday falls.
Diane Plese Age and Date of Birth
Diane Plese was reportedly born in 1959. Her exact date of birth has not been publicly established through a reliable source. Because of this, it is not possible to give a precise age for her on any specific day.
In 2026, someone born in 1959 would generally be 66 or 67 years old. Diane Plese’s age depends on whether her birthday has already occurred during the year.
Many online biographies repeat a specific age without providing a verifiable birth date. Such claims should be approached carefully. A reported birth year can offer a reasonable age estimate, but it does not confirm an exact birthday.
Diane Plese’s limited public presence may explain why her birth date has not received the same level of documentation as that of her former husband. Robert Herjavec’s business career and television appearances have generated extensive media coverage, while Diane has largely remained outside that environment.
For readers interested in Diane Plese’s age, the most responsible summary is that she was born in 1959 and is approximately 66–67 years old in 2026.
Birthplace and Canadian Background
Diane Plese was reportedly born in Parkdale, Toronto, Ontario, Canada. Parkdale is a well-known Toronto neighbourhood with a long history of cultural diversity and changing residential communities.
Her reported birthplace connects her to Toronto, a major Canadian city that has played an important role in her personal and family history. Toronto is also closely associated with Robert Herjavec’s early life and business career.
Diane Plese is Canadian by nationality. Her background is also commonly described as Croatian, with reports suggesting that her parents were Croatian immigrants.
Croatian heritage is an important part of the biographical information often associated with Diane Plese. However, detailed accounts of her parents, family history, and upbringing are not widely available. There is insufficient publicly verified information to describe her family’s immigration history in detail or to make specific claims about her childhood.
Her Canadian nationality and reported Croatian roots provide some background to her identity, but much of her early life remains private.
Diane Plese’s Croatian Heritage
Diane Plese is frequently described as having Croatian heritage. Reports commonly state that her parents were Croatian immigrants who settled in Canada.
Croatian communities have a longstanding presence in Canada, including in Ontario. Families with Croatian roots have contributed to Canadian business, healthcare, cultural life, and other professional fields. Diane Plese’s reported heritage places her within that broader Canadian multicultural background.
Still, it is important to distinguish between a widely repeated biographical detail and information supported by detailed records. Public sources do not provide a complete account of Diane Plese’s parents, their names, their arrival in Canada, or the specific region of Croatia from which they came.
Her Croatian heritage is therefore best described as reported family background rather than a fully documented family history.
Diane Plese’s Education
Diane Plese is known professionally as an optometrist. However, specific details about her education have not been reliably published in widely available biographical information.
Optometry is a specialized healthcare profession that generally requires professional education and training in vision care. Optometrists examine eyes, assess vision, identify certain eye conditions, and provide services related to visual health.
Diane’s reported profession indicates that she pursued a specialized career, but the name of the institution she attended, her graduation year, and her professional qualifications have not been clearly established in authoritative public sources.
Some online biographies may provide educational details, but repeated information is not automatically proof of accuracy. Without reliable confirmation, it would be inappropriate to assign a specific university, degree, or training history to Diane Plese.
Her career as an optometrist remains one of the clearest publicly associated details about her professional life.
Diane Plese Career as an Optometrist
Diane Plese’s profession is optometry. This career is significant because it represents a professional identity separate from her marriage to Robert Herjavec.
Optometrists work in the field of eye care. Their responsibilities can include conducting eye examinations, assessing visual performance, identifying certain eye health concerns, and helping patients manage vision-related needs. Depending on their qualifications and location, optometrists may also provide additional clinical services.
Diane Plese’s work in optometry suggests that she established a career in healthcare before or during her years of public association with Robert Herjavec. However, detailed information about her professional practice, workplace, career milestones, and current employment is not widely available.
It is also unclear whether she continues to practice optometry in 2026. There is no sufficiently verified public information confirming her present professional activities.
The limited coverage of Diane’s career reflects her overall preference for privacy. While Robert Herjavec’s professional achievements have been documented extensively through business news and television, Diane’s work has received comparatively little media attention.
Her professional background nevertheless remains an important part of understanding who she is beyond her former marriage.
Diane Plese and Robert Herjavec
Diane Plese became publicly known largely through her marriage to Robert Herjavec, a Canadian entrepreneur and television personality.
Robert Herjavec was born in Croatia and moved to Canada with his family when he was young. He later built a career in technology and business, eventually becoming associated with television programs focused on entrepreneurship and investment.
Diane and Robert reportedly married around 1990. Their relationship lasted approximately 24 years, making it a significant part of both their personal histories.
During their marriage, Robert’s professional career developed substantially. He became known for his work in technology and business and later gained international recognition through television appearances. Diane, meanwhile, remained much less visible in the media.
Their relationship attracted attention because of Robert’s growing public profile. However, Diane did not appear to pursue the same public career or media presence.
Information about their early relationship, including how they met and the circumstances of their courtship, is not extensively documented through reliable public sources. Claims about those details should therefore be treated cautiously.
Marriage Length and Family Life
Diane Plese and Robert Herjavec were reportedly married around 1990. Their marriage lasted approximately 24 years.
A marriage of that length represents a substantial period of shared family life. During those years, the couple raised three children while Robert developed his business career.
Diane’s role in the family has been discussed primarily in connection with her former marriage and their children. However, detailed information about their private household, daily life, and parenting arrangements has not been widely reported.
Because Diane has maintained a low public profile, there is limited information about her personal experiences during the marriage. Publicly available accounts tend to focus on Robert’s business achievements and the couple’s later separation rather than on Diane’s individual perspective.
Their marriage remains an important part of Diane Plese’s biography, but it should not define her entire identity. Her work as an optometrist and her role as a mother are also relevant to understanding her life.
Diane Plese Children
Diane Plese and Robert Herjavec have three children. Their reported names are Brendan, Skye, and Caprice.
The children are an important part of the couple’s family history. However, detailed information about their ages, careers, education, and current personal lives is limited in widely available public biographies.
Diane has generally maintained privacy around her family. As a result, it is difficult to establish a complete public timeline of her children’s upbringing or their relationship with both parents.
Robert Herjavec’s public career has generated interest in his family, but that does not mean every detail about his children is publicly confirmed. Information repeated across entertainment and celebrity websites may vary.
The reported names of Diane Plese’s children are commonly associated with her biography, but readers should avoid treating every online detail about them as verified.
Her role as a mother is one of the more important personal aspects of her life, even though she has not frequently discussed it publicly.
Diane Plese Divorce
Diane Plese and Robert Herjavec divorced after approximately 24 years of marriage. Reports commonly place the separation and divorce period between 2014 and 2016, although the exact timeline varies across sources.
The end of their marriage attracted public attention because Robert Herjavec was already a recognizable business personality. However, Diane’s own perspective on the divorce has not been extensively documented in authoritative public reporting.
It is important to avoid presenting unverified claims about the reasons for their separation or the private circumstances surrounding it. Public interest in a celebrity’s personal life can lead to speculation, but speculation should not be treated as fact.
The divorce marked a major change in Diane’s relationship with Robert Herjavec. It also became a significant event in the public narrative surrounding her.
After the marriage ended, Diane continued to maintain a relatively private life. Her limited public presence makes it difficult to provide a complete account of her activities during the years following the divorce.
Diane Plese Current Residence
Diane Plese is frequently reported to live in Toronto, Canada. However, her current residence has not been officially confirmed through reliable public information.
Toronto has a strong connection to her biography because it is her reported birthplace and the city associated with her Canadian background.
It would be inaccurate to state a specific neighbourhood, street, or residential address without authoritative confirmation. Diane’s private life deserves a clear distinction between publicly reported information and personal details that have not been verified.
Her reported connection to Toronto is therefore best presented as an unconfirmed residence detail rather than a definite statement about where she currently lives.
Diane Plese Net Worth
Diane Plese’s net worth is frequently estimated online at approximately $100 million. However, there is no authoritative public figure confirming that amount.
Net worth estimates for people who maintain private lives are often difficult to verify. Online articles may combine assumptions about family wealth, property, business interests, divorce settlements, and other financial matters without providing reliable documentation.
Diane’s reported association with Robert Herjavec has contributed to speculation about her financial position. Nevertheless, a former spouse’s wealth should not automatically be attributed to her, and the terms of any private financial arrangements should not be assumed.
Robert Herjavec has built a substantial business career, but his financial success does not establish Diane Plese’s personal net worth.
The reported $100 million figure should therefore be treated as an unverified online estimate, not a confirmed financial fact.
There is limited reliable information about Diane’s personal assets, investments, property ownership, business interests, or income. Without documented financial records or a credible statement from Diane herself, her actual net worth remains unknown.
Diane Plese Height and Physical Appearance
Some websites report Diane Plese’s height as approximately 5 feet 6 inches to 5 feet 7 inches. However, this information has not been reliably verified.
Celebrity biography websites frequently publish physical details without identifying their sources. Height estimates can therefore vary from one page to another.
Diane Plese’s physical appearance has not been a major focus of her public identity. Unlike television personalities who regularly appear in front of cameras, she has maintained a much lower level of public visibility.
The most accurate way to describe her height is to state that some online sources report an approximate range, while no authoritative measurement is publicly established.
Why Diane Plese Maintains a Low Public Profile
Diane Plese is known for staying away from media attention. Her former husband’s career has involved business television, public appearances, and media interviews, but Diane has generally chosen a different path.
There is nothing unusual about a person connected to a public figure preferring privacy. Not everyone associated with a celebrity wants to build a public identity or share personal information online.
Diane’s low public profile means that information about her life is often limited to basic biographical details, her career, her marriage, and her family.
This lack of public information also creates a challenge for anyone researching her biography. Online sources may repeat the same details without providing new evidence. Some claims may be accurate, while others may be based on assumptions or outdated information.
A responsible biography should acknowledge those limits rather than present uncertain details as facts.
Diane Plese: Life Beyond Robert Herjavec
Diane Plese is often introduced as Robert Herjavec’s former wife, but that description does not capture her entire background.
She is also known as a Canadian optometrist, a mother of three, and a person with reported Croatian family heritage. Her professional career represents an important part of her identity.
The public knows considerably more about Robert Herjavec’s business career than Diane’s personal achievements. That imbalance is largely due to their different levels of public exposure.
Diane has not built a highly visible media career, and she has not regularly shared details about her private life. As a result, her biography contains fewer documented milestones than those of her former husband.
Her story is a reminder that public recognition through a relationship does not necessarily reflect a person’s complete life. Diane’s career and family background deserve consideration independently of her connection to Robert.
Conclusion
Diane Plese is a Canadian optometrist whose public identity is closely associated with her former marriage to Robert Herjavec. Born in 1959 in Parkdale, Toronto, she is reported to have Croatian heritage and has built a life that has largely remained outside media attention.
Her marriage to Robert Herjavec lasted approximately 24 years and resulted in three children: Brendan, Skye, and Caprice. Although the divorce attracted public interest, Diane has continued to maintain a low profile.
Information about her exact birth date, education, current residence, height, and net worth remains limited or unconfirmed. The frequently reported net worth estimate of $100 million should not be treated as a fact.
Diane Plese’s story is not only about her connection to a successful entrepreneur. It also includes her professional identity as an optometrist, her Canadian background, her family life, and her privacy preference. Those details provide a more balanced picture of a woman who has remained largely away from the spotlight.
