She carries an innate & genuine flame for knowledge!

So much to write about Nina’s wealth. Working with her boils down to be a transformative experience that transcends voice trainings. She can literally change the way you perceive the world around you by invoking the power of words, precision in meanings & expressions.

Nina is a unique coach!

Nina is a unique coach who combines multiple innovative techniques of a wide range from breathing and visualization to arts and inspiring story-telling. Her biggest asset is the unmatched passion she demonstrates in every interaction that inspires and energizes, combined with her ability to tailor her coaching style depending on individual needs and preferences. Even though i work with Nina remotely, not physically, her coaching is equally impactful, as her dedication and energy breaks every barrier. I would strongly recommend Nina as a public speaking and work/life coach.

Her ability to tailor content to the needs of the team and provide practical, immediately applicable advice had a measurable impact on our colleagues’ communication skills.

Είναι εκπληκτική δασκάλα και άνθρωπος

Πάντα είχα τη απορία, γιατί κάποιοι ομιλητές ενώ έλεγαν πολύ ενδιαφέροντα πράγματα το ακροατήριο… αδιαφορούσε, ενώ άλλοι με λιγότερου ενδιαφέροντος θέματα το κοινό ήταν συνεχώς… μαζί τους!!! Την απορία μου έλυσε η γνωριμία μου με τη Νίνα, η οποία με έναν ιδιαίτερο και απλό τρόπο μου δίδαξε την τέχνη και το χάρισμα του λόγου. Η εσωτερική της διαύγεια και φωτεινότητα μεταδίδεται στο… μαθητή μέσω της φωνής και του σωστού λόγου. Είναι εκπληκτική δασκάλα και άνθρωπος. ΛΟΓΟ… τιμής.

One of the most rewarding experiences

Working with Nina was one of the most rewarding experiences I’ve ever had personally and professionally. Not only did she help me to improve my vocal delivery and presence on the stage, but she also taught me how to use my voice and words as a tool for expression. She was patient, understanding and always willing to go the extra mile for me. With her help, I was able to develop a deeper understanding of how my voice works and how it can be used in different contexts. My cooperation with her has been invaluable and I highly recommend her services if you want to take your vocal performance to the next level.

Nina is a unique personality

Nina is a unique personality and a very capable professional. I had the opportunity to realize her major impact in our senior and middle management since the first session on how “the voice impacts the leading presence”. The session on “how words influence our behavior, relations and overall our leadership” has been revealing for our people, who have rated with extraordinary scores. Last but not least, Nina has very strong emotional intelligence/very good intellectual judgement and therefore can be a very good Public Speeches coach.

Ένα ταξίδι στον κόσμο της φωνής και της ομιλίας σε κοινό

Τα μαθήματά μου με τη Νίνα ήταν πραγματικά ένα ταξίδι σε έναν διαφορετικό κόσμο, στον κόσμο της φωνής και της δημόσιας ομιλίας. Κατά τη διάρκεια των μαθημάτων μας, ασχοληθήκαμε με υπέροχα και ενδιαφέροντα θέματα. Συζητώναν ανεπιφύλακτα σε όποιον ενδιαφέρεται, να γνωρίσει από κοντά τη δουλειά της γιατί η Νίνα είναι εξαιρετική δασκάλα που με τις βιωματικές μεθόδους που χρησιμοποίησε μου άνοιξε νέους δρόμους για την προσωπική μου εξέλιξη.

She is a great coach!

I was always asking myself how I can improve my speaking skills, how I can be more impactful when I talk in small or bigger audiences, how I can deliver an impactful message in an era when the time is limited and in many cases we have to deal with virtual teams where the voice is even more important! I found out that there is a seminar about “Voice & Success” delivered by a soprano (Nina), I decided to attend it though it seemed a bit weird. It was a positive surprise! How the control of the voice (tone, depth, rhythm) with the support of the right breathing can change the way you speak and finally you deliver your message! Nina has a great way to navigate you through different paths and show you how to develop speaking skills with simple tips. Same time she teaches you how to control yourself, to be focused and finally to prepare yourself for a pitch, where you can give the best! She is a great coach! Thank you, Nina, for the experience!

New roads of exploration

I met Nina aiming to improve my voice. My lessons with her were not just learning voice techniques. It was a trip of self-awareness and an opportunity for personal growth. With Nina, I did not only improve my voice, but I discovered my “true voice”, the one that expresses emotions and inspires the others. Moreover, Nina opened to me new roads of exploration towards personal growth. I would like to thank Nina for the inspiration and the support in this trip of personal development.
