Assessor. Consultant. Practice Leader. Paralegal.



For over 20 years, I have been working in the property assessment and taxation field. During that time I have been responsible for preparing, reviewing and appealing a diverse range of property types.

My career began with the Ministry of Finance, and later with the Municipal Property Assessment Corporation ("MPAC"), working as an assessor on a wide array of property types.  For much of my time as an assessor I was responsible for the assessments on many of the largest and most complex industrial properties in Ontario.

In 2010 I left the public sector for consulting.  In my time as a property tax consultant I have reviewed and successfully appealed properties of nearly all types and sizes, including factories large and small, warehouses, apartment buildings, retirement homes, retail properties and aircraft hangers. Through either my direct or supervisory efforts I have achieved tax savings for clients in excess of $20,000,000*.

In time I realized that the corporate consulting model was not for me.  I prefer to provide services directly, not through staff of varying experience levels.  If I am going to be accountable to my clients, I want them to really be MY clients! Every client of Hintikka Consulting is my personal client, and will be treated as such.
