Building a better working world
I serve my clients by developing tax-oriented business solutions. Corporate tax departments are facing increasingly complex issues in recent years, driving the need for a comprehensive approach combined with traditional tax advisories. I see my mission as helping tax departments to progress from a defensive role as the guardians of compliance to a frontline position as professionals making a valuable contribution to corporate growth. I am also supporting the transformation of the wider tax industry by assisting my clients with organizational and business reforms and technology implementation.
