Our Founder 🙂

Kleanthis Patsoumis is the Founder and President of Atlas Consulting. For 50 consecutive years, he has  been active in the profession of Tax Accountant, Economist and Business Consultant. He planted the seed that became the tree called Atlas Consulting.

Our story has its roots back in 1972 – almost 50 years ago – when Mr. Kleanthis started his first business step as a Tax Accountant. He worked hard, constantly upgrading his knowledge, constantly innovating, instilling a love for the subject in his children, who continued his business and transformed that small accounting firm into Atlas Consulting. He retired in 2004 but since then, he contributes consulting to the projects undertaken by the company and of course he is an excellent Mentor for all of us.

Thank you Mr Kleanthis from the bottom of our heart for your offer, your inspiration, your contribution in everything!
