Meet Thrive Commercial Property Consultants


Hi, my name is Kathleen Kielenstyn. I decided to establish Thrive Commercial because I identified a lack of commercial lease support for small to medium businesses.  
With more than 15 years working in corporate real estate and managing property on behalf of ASX top 20 clients, I have worked for organisations such as Cushman & Wakefield, JLL and UGL, in senior lease management and negotiation positions covering Australia and New Zealand.  
Now I want to share my knowledge of the property lifecycle and negotiation skills to support emerging and  growing businesses, to take to their next level.

Hi, my name is Fiona Napier.
My extensive commercial real estate experience spans more than 25 years, having represented both owners and occupiers through the challenges of commercial and retail property leasing and management.
My past work includes leasing, centre management and asset management roles with Colliers, JLL, Cushman & Wakefield, Dexus and The Gandel Group. 
My passion is ensuring SME businesses have a voice while supporting them with their property needs, including landlord disputes, lease negotiations and lease exit strategies. I look forward to becoming a key member of your outsourced team.
