She has developed and molded her role as an external coach in order to encourage the anchoring of known and emerging resources that
teams and individuals alike withhold so they may progress, take initiative and adapt accordingly in the future. - As her professional identity grew and changed, she developed her supervisor side through working with coaches, executives and their teams. She combines benevolence and confrontation to allow for another perspective on the self, on situations, on challenges and on human interaction.

His identity as a support person finds its roots in one strong conviction: corporate roles undergo metamorphosis; each role entailing responsibility must develop its coaching stance.
