Being a leading EPC Contactor for over six decades, Archirodon has entered its seventh decade with the same energy and enthusiasm its two visionary Greek engineers and founders had, when they formed a joint entity to internationally expand their companies’ local Greek activities in 1959.
Without question, it takes a lot of hard work, talented individuals, elaborate planning, and determination to stay at the forefront of your industry for so long – and Archirodon, having been through thick and thin, has done exactly this, successfully and consistently, chasing challenges and turning obstacles into opportunities for growth. It is, however, our inherent ability to evolve as an organization that makes me proud to be at the wheel of this Company.
Listening to our Clients’ needs, following the market trends, avoiding shortcuts and compromises; all this has allowed us to find innovative solutions, become pioneers in changing the industry’s conventional approach and eventually transform from a construction company to a major EPC contractor, focused on adding value to our Clients’ business through our unique work. We have accomplished a distinguished record of performance in hundreds of large-scale projects, increasing tenfold the company's size and expanding its operations to more than 30 countries worldwide. Our response to the changing markets enabled a remarkable evolution and it is no understatement that these challenges are our drivers for shaping an even more robust and agile organization.
We are driven by the needs of the world, and we are committed to helping economies grow, improving infrastructure’s resiliency, and increasing access to renewable energy and resources while contributing to a safer, cleaner and more sustainable habitat for future generations.
Leading such an organization has been nothing short of rewarding and fulfilling. The teams I have been honored to work and grow with and the communities we serve, give an immense purpose to our joint efforts, instill daily new lessons and make me eager for what lies ahead.
Every day is a new opportunity to go one step further, give back to our world and achieve something greater with kindness and care.
