Richard Pappas started his real estate career aged 20 with Perth-based boutique agency City-Life Residential.
Two years later he co-founded specialist mortgage broking firm Focused Finance, and in 2004 purchased City-Life Residential.
Mr Pappas has since turned it into a major multi-disciplinary property group.
The companies have been consolidated under the Celsius Property Group brand, growing a pipeline of 160 managed properties to 1,150 over the past 10 years and delivering 250 development projects to date.
Despite the property downturn, Celsius has delivered a 918 per cent increase in revenue from 2015 to 2017.
Outside his business interests, Mr Pappas has entered the Comrades 89-kilometre marathon in South Africa, his homeland, to raise funds for the St Vincent De Paul Society.
