The Wealth of Diane Plese?

How rich is Diane Plese? As of late-2018, sources estimate a net worth that is over $100 million, earned through their divorce settlement which left her with half of her ex-husband’s wealth – prior to their divorce proceedings, Robert had a net worth valued at over $200 million. As she continues her endeavors, it is expected that her wealth will also continue to increase.

Early Life and Relationship

Diane grew up in Parkdale and is the daughter of Croatian immigrants who moved to Canada just before her birth,  but being born in the country, she became a Canadian citizen. Very little information is known about her childhood and education as she was not followed by the media until her marriage to Herjavec. It is known that after matriculating from high school, she pursued a pre-medical bachelor’s degree before going to medical school. After completing her medical education, she then focused on an optometric specialization. Optometry is the study on the eyes and visual systems, often looking for ways to cure defects or abnormalities. They specialize in treating various eye related disease and they are mainly consulted for correcting loss of eye focus through spectacles. The study has eventually evolved over time with optometrists now needing to have intensive medical training in the diagnosis and management of ocular diseases. Her profession allowed her to earn a significant amount of money, as most doctors do. However, her fame never really grew until her marriage.

Husband – Robert Herjavec

Robert grew up on a farm, living and working there with his family. At a young age he aspired to make films, and pursued such a career after graduating from the University of Toronto. His projects during the mid-1980s were such as “The Return of Billy Jack”, however, he later transitioned to sales and business after discovering his potential in the field, joining Logiquest and selling IBM mainframe emulation boards. His success in the field led him to become a general manager in the company, but he soon left to form his own company.

His first company was BRAK Systems, which focused on internet security software, which he subsequently sold for $30.2 million after rapid success. He had an eye for discovering businesses with the potential to earn huge amounts of money, and became an investor. Eventually his fame grew, as he was featured in investing reality shows such as “Dragons’ Den” and ABC’s “Shark Tank”. He gives investment advice, and invests in start-up companies usually leading to a profit. He has also written books on how to succeed in business including “The Will to Win: Leading, Competing, Succeeding”. He often appears on television, with fellow investors such as Mark Cuban, Lori Greiner, and Kevin O’Leary.

Marriage, Family, and Divorce

There is no information as to how Plese and Herjavec met, but it is known that they started their relationship in the 1980s, leading them to marry in 1990. They stayed together for 24 years and had three children together. According to reports, they separated in 2014, and completed their divorce two years later.

She received a substantial amount of money from the divorce, and then moved with her kids back to Canada. Many rumors started floating around that the reason for their divorce was due to Robert participating in the reality television competition “Dancing with the Stars”, in which he was partnered with professional dancer Kym Johnson, and he two started an extramarital affair, which lead to the breakdown of his marriage. This however, has never been confirmed.


Months after the completion of Robert and Diane’s divorce, he confirmed that he was in a relationship with Kym Johnson, aiding the rumors that she was the reason for his divorce. The two became engaged the following year and were married in Los Angeles, California, and the two now have twin children. In mid-2017, it was reported that Robert sued an ex-girlfriend for extortion and was counter sued for sexual assault. No additional details have been revealed about the suit but both cases were dismissed in 2018 and the case was withdrawn without any financial settlement. The case did not seem to be related to Diane in any way. He continues to live in the home he used to share with his ex-wife, a mansion in the Toronto area.

Diane on the other hand has faded away from the spotlight with her life in Canada being relatively quiet. It is not known if she is in a new relationship or remarried. There are also no details about her current endeavors. She has managed to keep her life and those of her children private – her eldest children are now in their late-teen years.
