While Mark and his brother Ian are the entrepreneurial spirit behind Fifteen Group which they founded in 1992, Mark’s primary role is evaluating potential new opportunities and overseeing the transaction side of the business.

Fifteen Group’s transactions range from simple property acquisitions to acquisitions of distressed debt, complex land entitlements, land development and vertical development.
