Diane Plese is a figure who draws public curiosity not primarily because of celebrity pursuits, but because her life bridges two worlds: a dedicated healthcare professional and the private partner of one of Canada’s most recognized business personalities. Across media coverage and public records, Diane’s name repeatedly surfaces in connection with her long marriage to Robert Herjavec, her career in optometry, her three children, and her life after divorce. What emerges from the available information is a portrait of a woman who maintained her professional roots, cultivated her family, and navigated intense public interest with discretion.
Early Life and Background
Diane Plese was born in 1959 in Parkdale, a neighborhood in Toronto, Ontario, Canada, to Croatian immigrant parents who moved to the country seeking new opportunities. Growing up in a culturally rich household, she developed values of determination, humility, and a strong work ethic. Her early life, though largely shielded from media attention, laid the foundation for her later pursuits in health care and family life.
From an early age, Plese was academically inclined, a quality that would eventually lead her toward the field of optometry. While specifics about her early schooling are not exhaustively documented, her later professional achievements suggest a focused and sustained dedication to her chosen discipline.
Becoming an Optometrist: Career and Professional Life
Diane Plese established herself professionally as an optometrist — a health care specialist focusing on eye care, visual systems, and the diagnosis and management of eye-related conditions. Optometry requires rigorous training, typically involving an undergraduate degree followed by specialized medical education and clinical experience. What is clear is that Plese pursued this path with seriousness and cultivated a respected career in the profession.
Her optometry practice provided her with financial independence and professional identity long before her name appeared widely in public searches due to her personal life. Even after her marriage drew media focus, Plese continued to uphold her professional commitments, balancing career and family responsibilities.
Marriage to Robert Herjavec: Wedding and Family Life
The story of Robert Herjavec Diane Plese is a defining chapter in both of their lives. Robert Herjavec, a Croatian‑Canadian entrepreneur and renowned investor on television shows like Shark Tank and Dragons’ Den, married Diane in 1990. Their wedding marked the beginning of a partnership that spanned more than two decades — an era during which Herjavec’s business achievements and public profile soared.
Throughout their marriage, Diane was known as a stabilizing presence, a supportive partner who raised their children while Herjavec navigated the demands of entrepreneurship and media exposure. Though the wedding itself was a private and personal event — not widely chronicled in celebrity outlets — the union endured for roughly 24 years before beginning to unravel.
Diane Plese Children: Parenting and Family Dynamics
Diane Plese children with Robert Herjavec include three offspring: Brendan, Skye, and Caprice Herjavec. These children grew up largely out of the media spotlight, in contrast to the intense scrutiny that sometimes surrounded their father’s career and public persona.
- Brendan Herjavec: The eldest, born in the early 1990s, later pursued higher education and professional endeavors in business and marketing.
- Skye Herjavec: Known to have studied business administration and forged her own professional path.
- Caprice Herjavec: A younger daughter who also pursued higher education and a career outside the public realm.
Parenthood was a central priority for Diane, and she is frequently described as having maintained a steady and nurturing role in her children’s lives throughout and after her marriage to Herjavec.
Divorce and Aftermath
After a long marriage, Diane Plese and Robert Herjavec separated in 2014, with their divorce finalized in 2016. The split attracted media attention largely due to Herjavec’s celebrity status, but both parties approached the legal proceedings with a preference for discretion.
The separation marked a profound shift in both their lives. Herjavec himself spoke candidly about the emotional difficulty he faced during this period, including struggles with depression — a topic he later discussed publicly.
In the years following the divorce, Robert Herjavec remarried Australian dancer Kym Johnson and expanded his family further. Diane, by contrast, chose to keep her life private, focusing on her children and professional identity.
Diane Plese Net Worth: Wealth and Financial Summary
Many online sources estimate Diane Plese net worth at figures ranging from around $25 million to as high as $100 million — though these estimates vary considerably across publications. The financial settlement from her divorce certainly contributed significantly to her wealth, with legal rulings requiring Herjavec to provide substantial compensation, estimated to total around $25 million.
It’s important to recognize that net worth estimates in public domains are often approximate and influenced by available data, particularly in cases where the individual maintains a low public profile. Nonetheless, the financial outcome of the divorce, combined with Plese’s own professional earnings, has positioned her with substantial economic independence.
Life Beyond the Public Eye
Unlike many spouses of public figures who pursue visibility through media or social platforms, Diane Plese deliberately chose a life away from the spotlight. She does not maintain active social media profiles and rarely participates in interviews. Her preference for privacy has become a defining aspect of her post‑marriage life, even as public interest in her past and her relationship with Herjavec continues.
Today, Diane is described as an example of quiet resolve: a professional who values her family and career over public perception, and a woman who carved a meaningful path amidst circumstances that could easily have pulled her into constant media scrutiny.
