From Our Founder & CEO
My professional odyssey began unexpectedly, stepping in as a Credit Controller. That moment ignited my passion for a career that spans over four decades in the ever-evolving landscape of Credit / O2C and across various work environments like Centralized, Decentralized and Global Business Services.
Callisto Grand, the name inspired by my grandfather’s houseboat, is more than an organization; it’s a celebration of the enduring enchantment found in the world of Credit. Few roles offer the unique ability to impact every stakeholder in a business positively. We believe work should transcend the confines of a 9 to 5 process or routine. Callisto Grand is committed to sharing the magic that makes each day more than just a process.
The greatest reward for my team and me is connecting with those who ‘get it’—individuals who share our passion.
We’re excited to meet you at our roundtables, conferences and training programmes sharing how you too can experience the same sense of fulfilment.
Looking forward to connecting,
Mark Harrison
Founder and CEO, Callisto Grand
