What Our Clients Say

Testimonials

In our clients’ words

Olga is one of the most professional, efficient, and personable attorneys I have ever met. She was indispensable during my Greek citizenship application and guided me through the daunting process every step of the way, from New York to Athens and back again. Quite frankly, I could never have done it without her. Aside from being a wonderful and kind person, she is incredibly skilled and knowledgeable. Her attention to detail is impeccable. I am always amazed that her quick response time (especially since I am in New York and she is 7 hours ahead of me in Athens). Olga is simply the best; there’s no one else in Greece I’d turn to for expertise in legal matters of all kind.

Tina Andreadis Tina Andreadis Senior Vice President of HarperCollins Publishers

I will always be indebted to Olga for sorting out a number of quite awkward legal issues to do with my Mother’s Greek estate. Somehow she was able to successfully navigate her way around the Greek system and resolve all the issues; some of them cross-border, some property related and some finance related. She is a most resourceful individual, this together with her intellectual ability and broad life experience enabled her to cut through the layers of bureaucracy that were experienced along the way. She works mainly on her own and that does give me as a client a full sense of commitment to my cause. I live in the UK and her drive to succeed as my legal agent in Greece was always re-assuring even when the going was quite tough. Even now a few years after her work was completed, I think I was very fortunate to find her to help me…….. thank you again, Olga.

Ann S.

I have been a client of Olga Kallergi’s office over the past couple of years, and she has helped me navigate the complexities of the Greek system for applying for citizenship and also purchasing property in Greece. She is knowledgeable, responsive, and has made the process much less difficult, providing good advice and clear explanations about different options. There is absolutely no way I could have ever done it without her assistance. I am very happy to recommend Kyria Kallergi for any of your legal needs in Greece!

Jeff Klapes Jeff Klapes Boston, USA

I am a continuing client of Ms. Kallergi and I am very satisfied with all the work she has done for me in what, admittedly, was a case that many other lawyers refused to take due its extreme complexity. Olga has gone above and beyond the strict interpretation of her job and helped me in myriad ways to resolve my case. I’m pleased to recommend her and do so without hesitation.

N.S.

The exemplary legal services of Olga Kallergi have helped me and my family many times over the years. Olga is an outstanding attorney with extensive experience in legal matters in Greece. She not only does her job well, but she truly cares about her clients and takes the time to answer questions. I highly recommend her.
