Assessment of damages


John has over 23 years' business analysis and commercial experience that he relies upon in investigating financial matters and providing reports in relation to commercial and family disputes, business valuations, assessment of damages and professional negligence matters.

John previously held a business analyst role for an international finance company. He has worked in commerce and also operated his own forensic accounting firm before joining Vincents in July 2004.

John's experience has led him to develop an approach to consider the key quantification and investigative issues when analysing situations and preparing reports.

As a mediator, John is often called upon as a neutral party to provide advice in alternative resolution matters. He has also developed an interactive process to deliver his single expert valuation engagements that allows parties to 'buy-in' to the process and result as opposed to encouraging further conflict (CDR).
