Our team


Grey Advantage differs from traditional business advisory roles in that it does not seek to leverage teams of less experienced or junior consultants to complete project tasks. Our Consultants have operated at a Partner level in a ‘Big 4’ Accounting Firm or Senior Executive Service (SES) Officer level in the public sector. This ensures that work is of the highest professional standard at all times.
