"Joining ATG was an easy decision. Quote to Cash is dynamic and a high-growth domain which offers endless opportunities to build lasting change partnerships in B2C, B2B and B2B2C in many sectors and geographies.

The Change Management lens in Quote to Cash is fascinating due to the wide definition of stakeholder or end-user; not only with cohorts in multiple divisions in our client businesses, but also their customers and resellers too – truly making no two working days the same.

I’m particularly excited to be in ATG where the domain expertise and spirit, shared across the 400+ ATG community, unites us in our passion to partner with our clients as they transform their people, processes and technology."
