Diane Plese: Biography, Career and Family

Introduction
Diane Plese is a Canadian optometrist who became widely known because she was married for more than two decades to Robert Herjavec, the Canadian businessman and television investor known from Shark Tank and Dragons’ Den. Most people search for her name because of that marriage, yet the more pages they open, the less certain the picture becomes. One page gives one net worth, another gives a figure four times larger.
This article solves that problem instead of adding to it. It explains who she is, what she did before she was famous by association, how her marriage and family life unfolded in public reporting, and what happened after the divorce. It also states plainly which claims are widely reported, which claims conflict, and which claims should be left out because they cannot be verified.

Who Is Diane Plese
Diane is a Canadian optometrist, best known publicly as the former wife of Robert Herjavec. That two-part description matters. The first part is her own profession, earned through years of study and practice in eye care.
Her public identity sits in an unusual place. Dozens of biography pages exist about her, but few rest on direct interviews or official records. Most repeat each other, sometimes adding a detail with each repetition, until a guess looks like a fact.
Early Life and Croatian Heritage
Diane was born in 1959 in Parkdale, a neighbourhood in Toronto, Canada, to parents who had immigrated from Croatia. That detail appears again and again across biography pages, and it fits the broader story of her family: a household shaped by immigration, hard work, and close family ties.
Her Croatian heritage is also part of how she and Herjavec connected, because he too came from a Croatian background.
Education and Career as an Optometrist
Diane trained as an optometrist, the healthcare professional who examines eyes, tests vision, prescribes glasses and contact lenses, and identifies eye conditions that need treatment or referral. It is demanding work that combines science, careful measurement, and direct contact with patients, many of whom are anxious about their sight.
The broad timeline of her training is widely reported, though the fine details are not. Reports say she studied in the late 1970s, qualified by the early 1980s, and was practising by the mid-1980s, which fits a birth year of 1959 and a clinic meeting in 1988.
How Diane Met Robert Herjavec
The story of how Diane met Robert Herjavec is one of the most repeated parts of her biography, and unusually, it is also one of the best supported. Widely reported accounts, including a mainstream report of a 2010 National Post interview, say Herjavec came to her Toronto eye clinic for a routine appointment in 1988. He was then a young man in his mid-twenties, working his way into business, and not yet famous.
The timing matters. They married in 1990, about two years after that first meeting, so their relationship formed before Herjavec’s major business success.
Marriage and Family Life
Diane married Robert Herjavec in 1990, and their marriage lasted for more than two decades, a length that stands out among high-profile couples.
As Herjavec’s career advanced, the family’s public profile advanced with it, through Dragons’ Den in Canada and then Shark Tank internationally.
Raising Three Children
Diane and Herjavec had three children together: Brendan, Skye, and Caprice. Their names are widely public, and they are now adults pursuing their own lives. That is as far as this article goes into their private details, deliberately.
One point of confusion deserves a direct warning. Different pages give different birth years for the children and sometimes list them in different orders.
Robert Herjavec’s Rise and BRAK Systems
To understand Diane’s married life, it helps to understand what her husband was building while she was building a family. Herjavec founded BRAK Systems, a Canadian internet security company, and grew it from a small operation into a business significant enough to attract a major buyer. Reports consistently say the company was sold to AT&T Canada in 2000 for a reported 30.2 million dollars.
Diane’s part in that tale, as reported, was supportive rather than operational. She was not a co-founder of BRAK, and this article does not claim otherwise.
Separation and Divorce Timeline
Diane Plese and Robert Herjavec separated in July 2014, after more than two decades of marriage.
The reasons for the divorce were never fully explained in a joint public statement, and this article does not pretend otherwise. Herjavec’s statement at the time was restrained, wishing his family love and peace.
| Date | Step in the process | What it means |
|---|---|---|
| 1990 | Marriage | Diane and Herjavec marry, about two years after meeting at her clinic. |
| July 2014 | Separation | The couple separate after more than two decades together. |
| March 2015 | Divorce announced and filed | The divorce becomes public; this is the year some pages call the divorce year. |
| June 2016 | Divorce finalised | The legal divorce is completed; Herjavec remarries about a month later. |
| 2019 | Settlement reporting | Later court reporting publicises the reported settlement terms below. |
Divorce Settlement and Net Worth
The financial side of the divorce is where reporting about Diane becomes most confusing. According to later court reporting, including reporting attributed to the Toronto Sun, Herjavec was ordered to pay Diane about 25 million dollars in assets, plus 125,000 dollars per month in support.
Ontario family law helps explain why the settlement was large.
Here is where the net worth confusion begins. Some pages take the reported 25 million dollar settlement and present it as Diane’s net worth, which is a reasonable starting point but still an estimate, because a settlement is only one part of total wealth.
Separate these four figures:
- Settlement: a divorce transfer.
- Monthly support: a recurring payment.
- Income: earnings over a period.
- Net worth: total assets minus debts.
| Claim | Status | Why |
|---|---|---|
| Settlement of about 25 million dollars plus monthly support | Widely reported | Appears consistently in later court reporting and multiple biography pages. |
| Monthly support of 125,000 dollars | Widely reported | Reported alongside the settlement figure in the same court coverage. |
| Total net worth of about 100 million dollars | Unconfirmed and conflicting | No official disclosure or audited source; other pages give far lower figures. |
| Total net worth of 20 to 25 million dollars | Estimate only | Essentially restates the settlement figure; not a verified total net worth. |
| Exact current wealth or property list | Not publicly confirmed | No reliable public record; detailed lists are guessing. |
None of this minimises Diane’s financial security after the divorce.
Life After Divorce and Privacy
Diane Plese has lived a private life since her divorce, and that privacy has been consistent enough to be treated as a deliberate choice.
That choice deserves respect. Diane was an optometrist before she was a celebrity spouse, and a mother throughout. After the divorce, she could return to being defined by those roles rather than by headlines.
Why Biography Pages About Diane Plese Disagree
Diane is a useful case study in why biography pages disagree, because the reasons are visible once you look for them. The first reason is copying. Many biography websites do not do original research.
The second reason is the incentive to be complete. A page that admits it does not know a person’s school or current home looks thinner than a page that supplies both, even if the supplied details are invented. Search results reward longer pages, so low-quality sites fill every template field, including fields for which no public information exists.
How to Read a Celebrity Biography Critically
Reading a biography critically requires a short set of habits, applied consistently, that separate pages doing real work from pages copying and embellishing.
- Check the core facts first. Confirm the profession, marriage dates, and children across several independent pages before trusting any single page.
- Look for qualifiers. Trust pages that say reported or estimated more than pages that state every figure as absolute fact.
- Separate settlement from net worth. Ask whether a wealth figure is a divorce transfer, monthly support, income, or a total net worth.
- Check the timeline. Distinguish separation, filing, announcement, and finalisation, because pages often use different steps as the divorce date.
- Ask where a detail came from. If a page gives a school name or measurement without a source, treat it as unverified.
- Prefer restraint over drama. A page that admits what it does not know is usually more reliable than a page that knows everything about a private life.
Use this checklist before sharing or repeating a claim from any biography page:
- Does the claim appear in more than one independent source, or only in pages that copy each other?
- Does the page label the claim as reported, estimated, or unconfirmed where appropriate?
- Does the page give a date, a named interview, or a court report for the claim?
- Does the claim confuse settlement, support, income, and net worth?
- Does the claim include private details, such as an address, that should not be public?
- Does the page admit at least one gap in its knowledge, as an honest profile should?
Applying these steps to Diane’s story gives a clear result. The core biography — Canadian optometrist, married 1990, three children, separated 2014, divorced 2016 — passes every test, because it appears across many pages and in mainstream reporting.
