With a rich background in the maritime world, Leontiadis brings a unique blend of technical expertise, deep client understanding, and a genuine passion for the sea, further elevating the group’s brokerage services across the Mediterranean.
With a distinguished career in yacht brokerage and a unique background that spans both the maritime and creative sectors, Theo brings over a decade of diverse experience and a deep passion for yachting to his new role. Based between Greece and Switzerland, he embodies the cosmopolitan spirit and excellence that define Sea-Alliance Group’s global presence.
“Theo’s multifaceted experience, industry knowledge, and natural flair for connecting with clients make him a powerful asset to our growing team,” said Roy Klajman, Shareholder & Co-Founder at Sea-Alliance Group. “His addition reinforces our commitment to offering tailored, high-quality service to yacht buyers and sellers worldwide.”
Theo’s journey into yachting began at a young age—introduced to boating by his parents, a formative gift he calls one of the greatest he’s ever received. This early bond with the sea has evolved into a professional career shaped by deep knowledge, global perspective, and a drive to offer his clients not just transactions, but trusted partnerships.
Over the years, Theo has built a reputation as a versatile and accomplished yacht broker with extensive hands-on experience in both sales and charter. He has worked with top-tier brokerage firms such as EKKA Yachts and First Quality Yachts, serving a wide-ranging international clientele. His career also includes time as a professional yacht skipper, giving him first-hand operational insight that few brokers possess—an advantage when advising clients on both the technical and lifestyle aspects of yacht ownership.
In addition to his yachting credentials, Theo has spent over a decade managing high-value guest services as a ski and water-ski instructor in elite destinations such as Gstaad and Mykonos. His ability to connect with clients, understand their needs, and deliver tailored, premium experiences has been a hallmark of his approach across industries.
Theo’s diverse background—encompassing brokerage, marine operations, and even a former career in film production—reflects his adaptability, creativity, and meticulous attention to detail. He is MYBA-certified, fluent in English and Greek, and conversant in French. Based between Athens, Corfu, and Gstaad, he brings a truly international mindset to his role at Sea-Alliance Group, offering a unique bridge between Central Europe and the Eastern Mediterranean.
