«I believe that every leader needs to constantly discover new ways, to invent new meanings and to accept new realities. I strongly believe that every leader desperately needs to do this in order to defy past success so that to move forward, to make new things happen and to keep magic going! But there comes a time when in order to do that he or she needs to fully reinvent his or herself. This is however easier said than done, for only a few enlightened ones can possibly undertake such a task alone effectively. Most of us need a good mirror. Most of us need somebody to help us shed light to dark places and to see ourselves and others from a different angle.

My mirror was Yiannis Koutsoumaris.

Yiannis has always been instrumental in the development of my career during a good number of years. His coaching has been lying in the center of my transformation to becoming a mature and senior leader. And as I am now accelerating on my way towards the most productive, I think, phase of my career, it is quite assuring to know that Yiannis is going to be there in order to offer me new options as I am navigating truly uncharted waters.»

«When going to a C-Level coach one never knows what to expect. Feeling sure about oneself and wondering about the result is the general state of mind.
Nonetheless, Yiannis was able to understand what I was telling him and most important he was able to read between the lines. He was able to build trust and entwine in a business as well as in a more personal level. He identified the key actors and was always able to see all sides of the story and suggest the best course of action that will not hinder my personal well being and on the same time being beneficial for the company.

He knew when I was ready for the change and when he should come out strong or just keep quite in order for me to find the way. Besides using textbook and custom made techniques he was able to identify avenues for potential growth and effective alternatives in dealing with situations that were alien to what I was accustomed.

I admire his way of becoming very involved with people and the way he spends an enormous amount of time to prepare for the session in order to be as close to the situation as possible, never loosing attention and always keeping focused. He is naturally posiitve, highly energetic and engaging. I was particularly impressed with his pursuit of excellence. The experience has altered my approach to business and life in general and I would wholeheartedly recommend Yiannis to anyone heaving business and / or personal issues.»
