Diane Plese: Life, Career, Marriage, Divorce, Net Worth, and Life After Robert Herjavec

Diane Plese is a Canadian optometrist and Robert Herjavec’s former wife.

Many people know her because of her marriage to the famous entrepreneur. However, Diane built her own career long before that relationship.

She studied optometry and worked in eye care for many years. She also played an important role in raising her three children.

Her private life has received less attention than Robert’s television career. As a result, some details about her life remain unclear.

This biography focuses on information that reliable sources support. It also separates confirmed facts from online claims.

Who Is Diane Plese?

Diane Plese is a Canadian optometrist who married Robert Herjavec in 1990.

She was born and raised in Ontario, Canada. Later, she studied optometry at the University of Western Ontario.

After completing her degree, Diane worked at several optometry practices. She later opened her own office.

Her career gave her an identity outside her marriage. Today, most public information about her comes from her career and divorce from Herjavec.

Diane Plese Biography at a Glance

Court records provide many of the most reliable details about Diane’s education, marriage, children, and divorce.

Early Life and Family Background

Diane Plese was born in Ontario in 1959.

She spent her early years in Canada and later pursued a career in healthcare.

Some websites say she was born in Parkdale, Toronto. However, court records only confirm Ontario as her birthplace and childhood home.

Her family background has received little coverage from reliable sources. Therefore, claims about her parents and childhood should be treated with care.

Education and Optometry Career

Diane chose optometry as her professional field.

She attended the University of Western Ontario after finishing secondary school. Her program lasted six years.

After graduation, she worked at different optometry practices. She later opened her own office.

Her education gave her the skills needed to work as an optometrist.

Diane’s career also shows that she had a professional life before her marriage became part of the public conversation.

What Does Diane Plese Do?

Diane Plese is an optometrist.

Optometrists provide eye and vision care. They check eyesight, prescribe glasses, and fit contact lenses.

They can also spot signs of some eye conditions and recommend further care when needed.

Diane trained in this field at the University of Western Ontario. Court records confirm her education and work history.

Reliable sources do not provide enough recent information about her current practice. Therefore, claims about a specific clinic or current patients should not be treated as confirmed.

How Did Diane Plese Meet Robert Herjavec?

Diane met Robert Herjavec through her work.

Robert became Diane’s patient when they were both in their late twenties.

Their professional connection later became a personal relationship. The couple married in June 1990.

At that time, Robert had not yet become the well-known television personality he is today.

His business career grew during their marriage. Diane continued to build her own life while also raising their family.

Diane Plese and Robert Herjavec’s Marriage

Diane and Robert married in June 1990.

Their marriage lasted about 24 years. The couple separated on July 24, 2014.

Together, they had three children: Brendan, Skye, and Caprice.

During their marriage, Robert built several successful businesses. He later became a television personality through shows such as Dragon’s Den and Shark Tank.

Diane remained more private than her husband.

Court records also show that she made important contributions to the family. Her role included caring for their children while Robert focused heavily on his business career.

Diane Plese’s Children

Diane and Robert have three children.

Their names are Brendan, Skye, and Caprice.

The children were young when their parents separated. Court records later described all three as adults.

Diane has generally kept her family life away from the media. Therefore, limited public information exists about her children’s private lives.

Why Did Diane Plese and Robert Herjavec Divorce?

Diane and Robert separated in July 2014.

Diane filed for divorce in March 2015. The divorce became final in 2016.

Court records discuss an affair involving Robert before the separation. The court stated that the affair led to the couple’s breakup.

Diane and Robert later dealt with financial and support issues through the family-law process.

Because the case involved private family matters, online stories often contain details that reliable records do not support.

Diane Plese Divorce Settlement

The financial result of the divorce often causes confusion online.

Some websites claim that Diane received a $25 million cash settlement. Court records show a more complex picture.

In 2018, the Ontario Superior Court ordered Robert to pay Diane an equalization amount of $2,689,558.

The court also ordered $125,000 in monthly spousal support for an indefinite period.

Child support also formed part of the court’s order during the relevant period.

The case involved several assets, properties, and financial interests. Therefore, the overall value cannot simply be described as one cash payment.

Did Diane Plese Receive $25 Million?

The answer needs some context.

Some family-law sources describe about $25 million in total assets and entitlements connected with the case.

However, that does not mean Diane received $25 million in cash.

The formal equalization payment ordered by the court was $2,689,558.

Diane also received monthly spousal support under the court order.

For this reason, the phrase “$25 million divorce settlement” can give readers the wrong impression.

Diane Plese’s Spousal Support

The Ontario Superior Court ordered Robert Herjavec to pay Diane $125,000 each month.

The court set the support for an indefinite period.

Robert appealed the support decision. In 2020, the Ontario Court of Appeal dismissed his appeal.

The appeal decision confirmed the trial court’s approach to Diane’s needs, resources, and contributions to the marriage.

This legal history provides stronger evidence than celebrity websites that simply quote a settlement figure.

Diane Plese Net Worth in 2026

Diane Plese’s exact net worth in 2026 is not publicly confirmed.

Several websites estimate her wealth at around $100 million. However, reliable court records do not support that exact figure.

Her financial position came from several sources.

These included her professional career, family assets, property interests, equalization, and spousal support.

For that reason, it is safer to describe her as financially secure rather than assign an exact $100 million net worth.

What Contributed to Diane Plese’s Wealth?

Diane had a professional career in optometry.

She also shared substantial family assets with Robert during their marriage.

The divorce proceedings later addressed the division of those assets.

Her financial position therefore reflects both her career and the financial arrangements from her marriage.

Life After Divorce

Diane has kept a low public profile since her divorce.

Unlike Robert, she does not regularly appear on television or at major public events.

Reliable sources provide limited information about her current daily life.

She has also avoided sharing many personal details with the public.

This privacy makes it difficult to confirm claims about her current career, relationships, hobbies, or social activities.

Robert Herjavec After the Divorce

Robert Herjavec continued his business and television career after the divorce.

He became widely known through Dragon’s Den and Shark Tank.

Robert later married professional dancer Kym Johnson. The couple met while working together on Dancing with the Stars.

They married in 2016 and later welcomed twins.

Robert’s later success has kept his personal history in the public eye. Diane, in contrast, has chosen a much quieter life.

Diane Plese’s Public Image

Diane Plese has maintained a private public image.

She rarely appears in interviews and has little social-media presence.

This limited visibility has created room for online speculation.

Many biography websites repeat the same details without showing reliable sources.

A more accurate profile should focus on information supported by court records and credible reporting.

Physical Appearance

Several websites publish claims about Diane’s height, weight, hair color, and eye color.

However, reliable sources do not confirm these details.

For that reason, exact measurements should not appear in a fact-based biography.

Her private lifestyle also means that recent photographs and personal style information are limited.

Philanthropy and Community Work

Some websites claim that Diane supports eye-care charities and mentors young professionals.

However, reliable sources do not provide enough evidence to confirm these claims.

It is therefore better not to describe specific charitable activities as established facts.

Her professional background in optometry remains the strongest documented part of her career outside her family life.

Social Media Presence

Diane has maintained a very limited online presence.

There is no widely recognized verified Instagram or other major social-media account associated with her.

However, the absence of a verified account does not prove that she intentionally avoids social media.

Several unofficial accounts may use her name.

Readers should therefore avoid assuming that every Diane Plese profile online belongs to the real person.
