For 5 decades Mr. Kleanthis Patsoumis he has been active in the profession of Tax Accountant, Economist and Business Consultant. He planted the seed that became the tree called A.TL.AS Consulting.
Our story has its roots back in 1972 – 5 decades 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 A.TL.AS 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.
