Maritsa Lazari & family

Maritsa Lazari is the widow of late billionaire Christos Lazari, who died in 2015, a few months shy of their 50th wedding anniversary.

The couple, who met in London, married in 1965.

Christos eventually created a successful fashion line called Drendie Girl. The couple used the profits from that business to buy up property.

Lazari Investments owns more than 3 million square feet of commercial real estate in London, mostly office space that it rents out.

Maritsa was a cofounder of the real estate business and serves as a director. Her three children are also involved in the company.
