about the practice

Twenty years of customer experience, written down slowly.

Silvia Montero Collado is an executive advisor on customer experience and service operations. She has led CX programmes at retail banks, B2B software companies, and consumer-services groups across the Americas, Europe, and Asia, and now writes about the work for the executives who come after her.

The library is free. The advisory practice is not. It runs by referral, two engagements at a time. A small number of new conversations open each quarter.
