Diane Plese is best known as the first wife of Robert Herjavec. Robert later became famous as a businessman and a star on Shark Tank. But Diane had her own life and career long before people knew her name.
She worked as an optometrist and built a quiet life in Canada. She also became the mother of three children. For many years, she stayed beside Robert while he worked on his business and slowly became very successful.
So, who is Diane Plese beyond being Robert Herjavec’s first wife? In this article, we will look at her early life, career, marriage, family, role in Robert’s success, divorce, money, and life today in 2026.
Who Is Diane Plese?
Diane Plese is a Canadian optometrist. She became widely known because of her long marriage to Robert Herjavec. Robert is a businessman, investor, and TV star who became famous through shows like Dragon’s Den and Shark Tank.
Even though Robert became very famous, Diane Plese never seemed interested in living a public life. She did not try to become a TV star. She also stayed away from social media and gave very few interviews.
That is one reason people remain curious about her. Diane was part of Robert’s life before the money, TV shows, and fame. She saw the early years when his future was still uncertain.
Diane Plese’s Early Life
Several online reports say Diane Plese was born in 1959. If that year is correct, she would be about 67 years old in 2026. However, her exact birthday has not been clearly confirmed by a strong public source.
Diane grew up in Canada. Some reports say she was raised in the Toronto area and came from a family with Croatian roots. Her parents are often described as Croatian immigrants who made a new life in Canada.
Very little is known about her childhood. Diane has always kept her family story private. There are no many public details about her parents, brothers, sisters, or school years. This makes her different from many people connected to famous TV stars.

Diane Plese’s Career as an Optometrist
Before Diane Plese became known as Robert Herjavec’s wife, she had her own career. She trained as an optometrist and worked in eye care. An optometrist helps people with eye health, vision tests, and glasses.
Reports say Diane started working in the field during the 1980s. Court records from later years also show that she worked full-time as an optometrist during the early part of her marriage.
She even ran her own office. This is an important part of Diane Plese’s story. She was not simply living in the shadow of a successful husband. She had her own work, income, and professional life before Robert became rich and famous.
How Diane Plese Met Robert Herjavec
The story of how Diane Plese met Robert Herjavec is one of the most interesting parts of their relationship. Reports say they first met in 1988 when Robert went to her clinic for an eye checkup.
At that time, Robert was not yet the TV star people know today. He was still trying to build a future in business. Diane later reportedly said she liked his energy and excitement about life.
Think about how simple that first meeting was. One person went for an eye appointment, and that meeting later turned into a marriage that lasted more than two decades. They began dating and slowly built a strong bond.
Diane Plese and Robert Herjavec’s Wedding
After dating for around two years, Diane Plese and Robert Herjavec married in 1990. Reports say the wedding took place at a Croatian church in Ontario, with some sources naming Mississauga.
Their wedding happened long before Robert became a major TV name. At that point, the couple was still building their life together. They were not yet living the rich lifestyle that came years later.
Diane and Robert shared family roots linked to Croatia. Their wedding at a Croatian church also showed the importance of family and culture in their lives at the time.
Diane Plese’s Role in Robert’s Success
Robert Herjavec worked very hard during the early years of the marriage. He later built BRAK Systems, a company linked to internet security. Reports say the company began from the family home before it grew into a major business.
Diane Plese was there during those early years. She had her own career while Robert was trying to grow his company. Later court records showed that Diane reduced her work after the couple started having children.
BRAK Systems became a big success. In 2000, Robert sold the company for about $30.2 million. That sale changed the family’s financial life in a major way and helped Robert move into a much bigger business world.
As Robert spent more time on his work, Diane slowly took on more responsibility at home. She later left full-time work and focused more on the family. This helped Robert give more time and energy to his growing business career.
Diane Plese and Robert’s Three Children
Diane Plese and Robert Herjavec had three children together. Their son Brendan was born in 1993. Their daughter Skye was born in 1996, and their youngest daughter Caprice was born in 1998.
Diane’s role as a mother became a major part of her life. After the children were born, she worked fewer hours. Later, she stopped working outside the home and spent more time raising the children and managing family life.
The children mostly grew up away from heavy public attention. Diane seemed to prefer that. While Robert was becoming more famous, she kept the family side of their life much quieter.
Brendan later moved into business work. Skye also studied business and worked in finance. Caprice became active in sports during her school years and later moved into consulting work.
The family looked successful from the outside. Robert’s career was growing, the children were getting older, and the family had built a very comfortable life. But behind the scenes, the marriage was slowly moving toward a difficult change.
Why Did Diane Plese and Robert Separate?
Diane Plese and Robert Herjavec spent many years together. They built a family, raised three children, and watched Robert’s business life grow. But after more than two decades, their marriage started to change.
The couple separated in July 2014. By that time, they had been married for about 24 years. The news surprised many people because they had been together for such a long time.
Robert later said the year had been very hard for him and his family. He also said he wanted love and peace for everyone as they moved forward. Diane shared very little in public and stayed mostly quiet during the split.
There were also reports about another woman and possible relationship problems. But these claims should be treated with care. The safest fact is that Diane Plese and Robert’s marriage had broken down and they decided to go separate ways.
Diane Plese and Robert Herjavec’s Divorce
Diane Plese filed for divorce in March 2015 after the couple had already separated. Their divorce later became a major topic because Robert was very rich and famous by that time.
The case was not only about ending the marriage. It also included money, property, and long-term support. Diane had spent many years helping with the home and children while Robert focused more on business.
Their divorce was completed in 2016. But some money issues continued in court after that. This made the case even more public.
The long marriage also mattered in the final result. Diane had stepped away from her career for the family. That became an important part of the court’s view when it looked at support and money.
Diane Plese’s Life After Divorce
After the divorce, Diane Plese did not try to become more famous. She did not join reality TV or use her story to build a public image.
Instead, she returned to the quiet life she had always preferred. She stayed away from interviews and did not appear often at public events.
She also does not seem to have a major verified social media account. That is why there are not many fresh photos or daily updates about her life.
There is also no strong public proof that Diane has remarried. Her private life after Robert has stayed mostly unknown. She seems to value peace, family, and privacy more than public attention.
Where Is Diane Plese Today in 2026?
As of 2026, Diane Plese is believed to still have strong ties to Canada. Some reports place her in the Toronto area, but her exact home is not clearly confirmed by a strong recent source.
This is an important point because many websites give exact details without proof. Diane has kept her life private, so it is better not to guess where she lives today.
She is now known as a mother of three grown children. Brendan, Skye, and Caprice have all moved into their own adult lives and careers.
Diane Plese may no longer appear often in public, but people still search for her because of her long history with Robert Herjavec. Her story is also interesting because she had her own career and helped build a family long before Robert became a TV star.
