Inspiring the extraordinary

Our Story

Our Story begins in 2002, when our founder and namesake, Kyriacos “Theo” Theodosiou, formed THEO Executive Group to reveal the extraordinary in people and organizations. For much of the last 20 years, our emphasis has been on elevating the impact of healthcare and adjacent industries.

As we look to the future, theo Transformation Advisory endeavors to make a broader impact on the world. With trust and partnership embedded, our focus expands to other industries and markets that play a critical role in the wellbeing of people, organizations, and communities. Through our unique, human-centered approach we partner with our clients to transform Talent, harness the power of Culture as a strategic advantage, and deliver organizations transformed.
