Gavin Pearson is head of the UK disputes, investigations and valuations team at Quantuma. He is experienced as a forensic accountant and expert witness, having acted as expert accountant in many civil, family, and criminal matters in the UK and overseas.

Gavin Pearson is great on his feet and commercial. His evidence is very compelling because it's accessible. He is able to explain in basic terms how valuation works.

Gavin is excellent. He has good judgement and is very commercially astute. I recommend him highly.
