I am a bit of a Jack of all trades. Aanalyst (happy to analyse financial markets and management styles), down to earth & roll up my sleeves type of guy (us Americans, aren’t we all?), a trifle eccentric (for some of us Brits a badge of pride), a yacht captain (us Greeks, we learn to swim before we walk), an olive grove farmer

My own businesses from 2009 until 2019

In 2018 and 2019 I converted most of my residential properties in Greece to tourist accommodations, available through booking platforms, such as and

From 2009 to 2017, I was involved with the setup and operation of a Family Office, managing my financial investments as well as my real estate investments in Greece.

I have extensive hands-on experience & detailed knowledge of yacht management. This includes the planning & execution of a long passage in 2009 as well as related improvement projects and ongoing maintenance of my steel motorsailer.

My careers in finance and IT/maritime sector until 2008

In 2008, I completed a 20-year long career in the analysis of securitisations/structured finance investments and, initially, in banking. Successively based out of New York, Tokyo and London, I hired, trained and managed financial analysts and analysed transactions around the world. I published, or edited, countless reports and press releases. I became well-versed in legal documents & opinions, especially for trusts and Special Purpose Vehicles. In Japan, became skilled in commercial real estate valuation. 

Additional work experience in information systems gained from 1984 to 1989 in the maritime industry in New York

I am the co-organiser of the "Vienna Book Group" at InterNations Vienna. Members of Internations are meeting on a monthly basis to discuss in English a book that we have preselected. It is so gratifying to view our complex world not only from an author’s point of view, but also from that of fellow book club readers!  

Xenia, Myriam, Eva & Rena were four powerful women which played an important role in my life as my mentors. In addition, they are worth mentioning as role models because they offered a lot with their ethos, hard work and dedication to society. Therefore I named after them my apartments in Athens. Their story is told and done justice.

My sea voyage from London to Lixouri

In 2009, I sailed my yacht "Mondo Cosseri" from Burnham-On-Crouch on the East coast of England to Lixouri in Kefalonia (4,000 kilometres over water).
