WHY: Runs real estate empire built by her father Igor Olenicoff. Newport Beach-based Olen Properties Corp. is one of OC’s largest privately held real estate firms, with a portfolio that now spans 8M square feet of office and flex space and 17K-plus residential units across California and seven other U.S. states, serving more than 20K tenants.
