About Thomas

Are you looking for a General Manager who can grow your business while remaining fully operational on the ground?

I support leaders, SMEs, mid-cap companies, investors, and real estate professionals in developing, structuring, and optimizing their activities. My career has led me to manage property dealing companies, oversee real estate operations, and serve as the general manager of a social-purpose hotel.

I am involved in both strategy and execution: operations management, leadership, organization, business development, financial steering, negotiation, project management, property renovation, and performance improvement.

Accustomed to demanding environments, I know how to structure an organization, manage change, unite teams, and make quick decisions to achieve concrete objectives.

My interventions include:

• Part-time General Management or Operations Management (COO)
• Business structuring and development
• Team management and organization
• Financial and operational steering
• Real estate development and partnerships
• Renovation project management
• Process optimization and change management

My goal is simple: to deliver measurable results, pragmatic solutions, and a sustainable vision to drive your company's growth.
