- Founder, Core Concepts Design
Dinos Chamalis
Dinos brings a rare combination to brand and digital transformation work: nearly a decade inside Accenture Technology Consulting, followed by 14 years building and running his own consultancy.
Greek-Peruvian by background and raised in Greece, Dinos earned his MSc in Distributed Systems and Networks from the University of Kent before spending almost ten years at Accenture, delivering technology and transformation projects for organizations including Philip Morris, HSBC, Barclays, SAP, Santander, Lloyds Banking Group, BT, and CLP Power Hong Kong — work that took him from Hong Kong and Switzerland to Milan and Munich, and taught him how large, complex organizations actually make decisions.
That enterprise consulting foundation is what sets Core Concepts Design apart. In 2012, Dinos left Accenture to found Core Concepts Design, first in London and later expanding into the US market from Chicago and Miami. What began as a digital marketing venture — backed by an early round of Angel investment from a London-based media venture — has grown into a boutique consultancy trusted with more than 3,000 projects across 14 years, earning 850+ client reviews along the way. The portfolio spans high-visibility work like the Chicago Thanksgiving Parade, the Chicago Bulls’ team physician, and multiple TEDx events, alongside recognition from major design awards.
Today, with studios in Grand Rapids, Michigan and Thessaloniki, Greece, Dinos leads Core Concepts Design’s mission: applying the rigor and strategic discipline of enterprise consulting to help ambitious brands transform — not just their websites, but how they show up, compete, and grow.
