Professional Summary

I have worked as a leasing operative in the  Melbourne CBD for the past eight (8) years and hold a position as a Director in the market leading Colliers International Melbourne leasing team.

During this time I have proven to be one of Melbourne's most active agents in the industry, concluding over 600 leasing transactions on behalf of my clients across new development and existing buildings in the Melbourne CBD, Docklands and Southbank precinct's to well known and reputable tenants.

I am an extremely motivated and highly strategic operative that understands the leasing process and tenant’s relocation drivers.

In 2019, I concluded a total of 79 leasing transactions in the Melbourne CBD and Docklands, of which 84% of these were unrepresented tenants ranging from 8,595sqm to 45sqm in size.

I pride myself on my organisational and communication skills, which have enabled me to develop a dedicated focus that ensures my clients and tenants receive an unparalleled service.

Please feel freel to contact me to discuss your property objectives.
