In this article, we will look at Diane Plese’s age, early life, family roots, career, marriage, children, divorce, net worth, and life today. Everything is explained in a simple and clear way, so readers can understand her full story without confusion.

Diane Plese Profile Summary

Who Is Diane Plese?

Diane Plese is a Canadian optometrist. An optometrist is an eye doctor who checks people’s eyes and helps with vision problems. Before the world knew her as Robert Herjavec’s ex-wife, Diane had a real career in the medical field.

She became widely known because of her long marriage to Robert Herjavec. Robert is a Croatian-Canadian businessman, investor, and TV personality. Many people know him from Shark Tank and Dragon’s Den, where he listens to business ideas and invests money.

But Diane Plese was not just a celebrity wife. She was with Robert before his huge success. She saw the early days, the hard work, and the slow rise before he became a famous face on TV. That makes her story more important.

Diane has always kept a low profile. She does not share much about her private life. She is not active on big social media platforms, and she does not often appear in public. This quiet life makes many readers even more curious about her.

Diane Plese Early Life

Diane Plese was born in 1959 in Parkdale, Toronto, Canada. As of 2026, she is around 67 years old. Her exact birthday and birth month are not publicly known, so most sources only mention her birth year.

She grew up in Canada, but her family story connects to Croatia. Her parents were Croatian immigrants who moved to Canada before she was born. This means Diane was raised in Canada, but her family roots came from Croatian culture.

There is not much public information about her childhood. Details about her siblings, early school life, and family home are private. This is not surprising, because Diane Plese has always stayed away from too much public attention.

Still, we can understand one thing clearly. Diane came from a family that likely valued hard work, family, and stability. Later in life, these values seemed to show in her career, marriage, and role as a mother.

Diane Plese’s Nationality and Family Roots

Diane Plese is Canadian by nationality. She was born and raised in Toronto, so Canada is her home country. She has spent most of her life there, and reports say she still lives in Toronto today.

Her ethnic background is often described as white, and her family roots are Croatian. This matters because Robert Herjavec also has Croatian roots. Their shared background may have helped them feel connected when they first began dating.

Robert was born in what is now Croatia before his family moved to Canada. Diane was born in Canada to Croatian immigrant parents. So, even though they had different childhood stories, they shared a strong link through culture and family history.

Their wedding also showed this connection. Diane Plese and Robert Herjavec married in a Croatian church in Ontario. That detail gives readers a small look into how important their roots may have been in their early life together.

Diane Plese Education and Career

Diane Plese studied in college in the late 1970s. After that, she followed a path in optometry. She completed her eye care training in the early 1980s and became an eye doctor.

Her work as an optometrist was important. She helped people with eye checks, vision care, and related needs. It was a respected job and showed that Diane had her own skills before she became linked to a famous businessman.

She worked in an eye clinic for several years. In fact, this job became a big part of her life story because it was where she first met Robert Herjavec. A normal eye appointment later turned into a long marriage.

Some reports say Diane later gave up or stepped away from her optometry work to focus on her children and family life. This shows that her life changed a lot after marriage, especially as Robert’s business world became bigger and busier.

How Diane Plese Met Robert Herjavec

Diane Plese met Robert Herjavec in 1988. At that time, she was working as an optometrist. Robert visited the eye clinic where she worked for a regular eye appointment.

It sounds like a simple meeting, right? A patient walks into a clinic, meets an eye doctor, and leaves. But for Diane and Robert, that small moment became the start of a long love story.

Reports say Diane was drawn to Robert’s outgoing nature. He was not yet the very famous Shark Tank star people know today. He was still building his path and trying to grow in business.

After meeting at the clinic, Diane and Robert started dating. They dated for about two years before getting married. Their early relationship was built before big TV fame, huge money, and the public attention that came later.

Diane Plese and Robert Herjavec’s Marriage

Diane Plese and Robert Herjavec got married in 1990. Their wedding took place in a Croatian church in Ontario, Canada. This choice reflected their shared Croatian background and family values.

At the time, Robert was not yet a global TV star. He was a young man with big dreams and strong business goals. Diane was by his side during a time when his future success was still being built.

Their marriage lasted for more than two decades. Most reports say they were married for 24 years before separating in 2014. Some sources describe the marriage as 25 years because the divorce was completed later.

During their marriage, Diane and Robert built a family and raised three children together. They also moved from a more private life into a much more public one as Robert became richer and more famous.

Life Before Robert Herjavec Became Famous

Before Shark Tank, red carpets, and public fame, Robert Herjavec was building his business life step by step. Diane Plese was with him during those early years, when success was not yet certain.

Robert started BRAK Systems, a Canadian internet security software company, in the basement of their home. This detail is important because it shows how close Diane was to the beginning of his business journey.

Starting a company from a basement is not easy. It takes time, stress, and strong support at home. Diane was part of that life before the big money arrived. She saw the hard work behind the success.

In 2000, Robert sold BRAK Systems to AT&T Canada, now known as Allstream, for about $30.2 million. This sale changed the family’s life in a major way and helped Robert become a very wealthy businessman.

Robert Herjavec’s Rise and Diane’s Role

After the sale of BRAK Systems, Robert Herjavec became more known in the business world. Later, he appeared on Dragon’s Den in Canada and Shark Tank in the United States. These shows made him a familiar face to millions of viewers.

He also founded The Herjavec Group in 2003. The company became one of Canada’s major cybersecurity firms. Robert’s work in tech and security helped him build a much larger fortune over time.

Diane Plese was not the public face of these companies. She did not sit on TV beside him as an investor. But she was part of his home life during the years when his name, money, and business power grew.

This is why many readers want to know more about Diane. She was not just someone who appeared after success. She was there during the early climb, when Robert was still turning his ideas into real business wins.

Diane Plese Children

Diane Plese and Robert Herjavec have three children together. Their names are Brendan, Skye, and Caprice Herjavec. Their children became an important part of Diane’s life, especially after she stepped away from public attention.

Brendan Herjavec is their eldest child. He was born in 1993. He studied business and later worked in strategy and business growth. He has also been linked to business talks and a podcast where he speaks with people who build companies.

Skye Herjavec was born in 1996. She studied business administration and management at the University of Southern California. She also worked in the business and finance world. Like her parents, she has shown interest in serious work and growth.

Caprice Herjavec was born in 1998. She was active in sports during school and college. She joined rowing at Barnard College of Columbia University. Later, she worked as a consultant in New York City.

Diane Plese Divorce From Robert Herjavec

Diane Plese and Robert Herjavec separated in July 2014. Their divorce was announced in March 2015. After many years of marriage, their split became public and got a lot of attention because Robert was already famous.

Their divorce was completed in 2016. Reports say their marriage ended after about 24 years. Some sources say 25 years because the legal process finished later. Either way, they spent a very long part of their lives together.

The reason for the split was not fully shared by Diane and Robert. However, reports linked Robert to actress Danielle Vasinova in 2014. Because of this, many people believed the marriage ended after trust problems.

Robert later spoke about how hard the split was for him. He said it was a very painful time, mainly because his children stopped speaking to him for a while. This shows that the divorce did not only affect the couple. It affected the whole family.

Diane Plese’s Net Worth

Diane Plese net worth is often reported to be around $100 million. This number is only an estimate. Her money is believed to come from her career, divorce settlement, and property matters after her marriage ended.

Reports say Diane received around $25 million from Robert Herjavec’s wealth. She was also linked to a $2.5 million equalization payment. At one point, Robert was ordered to pay monthly support, but reports say this later changed in court.

Diane also received property as part of the divorce story. Reports mention the family’s Caledon ski chalet and a Florida property. These details made the divorce one of the most talked-about splits linked to Shark Tank.

It is important to say that Diane did not receive half of Robert’s full wealth. Some assets were handled under Canadian law. This is why her final settlement was large, but not equal to half of everything Robert owned.

Where Is Diane Plese Today?

As of 2026, Diane Plese lives a very private life. Most reports say she is in Toronto, Canada. She does not appear often in the media and does not share much about her daily life.

There are no strong public reports that Diane has married again. Her relationship status is not clearly known. Because she likes privacy, it is better not to guess about her personal life.

Diane is also not active on major social media platforms. Some reports say an account with her name exists on X, but it has not been active for many years. This fits her quiet way of living.

Today, many people still search for Diane Plese because of her past with Robert Herjavec. But her life now seems peaceful and private. She appears to have chosen a calm life away from cameras.

The End of the Story

Diane Plese is often introduced as Robert Herjavec’s ex-wife, but her story has more depth. She was an eye doctor, a wife, a mother, and someone who stood beside Robert before his huge success.

Her life changed when Robert became rich and famous. Their marriage brought family, wealth, public attention, and later a difficult divorce. Still, Diane handled her life with privacy and quiet strength.

In 2026, Diane Plese remains a private person. She does not chase fame, interviews, or attention. That makes her story different from many people linked to famous names.

In the end, Diane Plese’s story is about more than divorce money or a famous ex-husband. It is about a woman who built her own career, raised a family, lived through public change, and then chose peace away from the spotlight.
