Leadership Team

The people behind the partnerships. Decades of maritime experience, guided by a single principle: our clients come first.

Dimitrios Koukas, Chief Executive Officer

Dimitrios Koukas

Chief Executive Officer

With over four decades in the maritime industry, Dimitrios Koukas founded Optima Shipping Services in 1981 with a singular vision: to provide genuinely independent shipbroking advice, free from the conflicts of interest that defined the era's large brokerage houses.

Under his leadership, Optima has grown from a single desk in Athens to a global operation spanning five offices across three continents. The firm's expansion into ten integrated service lines, from Sale & Purchase and Newbuildings to ESG advisory and cybersecurity, reflects his belief that the modern shipowner deserves a partner, not just a broker.

Recognized by Lloyd's List among the Top 10 Shipbrokers globally, Dimitrios remains actively involved in the industry through BIMCO, the Hellenic Shipbrokers Association, and maritime education initiatives across Greece.

"In forty-three years, the market has taught us one thing: the shipowners who succeed are those who choose partners, not brokers."

The Optima Way

We hire specialists, not generalists. Every desk at Optima is led by someone who has spent a career mastering their discipline. But what connects our people across five offices and ten service lines is a shared belief: the best deals happen when trust comes before transaction.
