Daniel Greiner

As a Principal at HAGER Executive Consulting, I lead our global Oil & Gas Practice and am further building our Travel & Aviation Practice at Hager Executive Consulting, partnering with energy, industrial, and aviation companies to secure top-tier executive and leadership talent for critical, value-driving roles.

Having lived and worked in the United States, Europe, Australia, and the Middle East, I bring a deeply international mindset and a strong understanding of diverse business cultures, leadership expectations, and regional market dynamics. This background enables me to advise clients with cultural sensitivity and strategic clarity, particularly in globally interconnected industries where leadership effectiveness depends on navigating complexity across borders.

I work closely with senior stakeholders to shape talent strategies, deliver targeted executive search mandates, and build leadership teams that strengthen performance, resilience, and long-term growth. Leveraging a strong international network, I execute complex cross-border searches with speed, precision, and discretion.
