About Mandy

I support organisations in executing complex transformations—from post-merger integration to change management. With 15+ years of experience in global projects (EMEA, food ingredients/B2B), I specialize in interim mandates (6+ months), ensuring strategies translate into adoption, alignment, and sustainable results.

Experience

    Interim Project Manager
    June 2025 - Today (1 year and 1 month)
    Hamburg, Germany
    I specialise in leading complex post-merger integration and transformation projects where communication,
    alignment and structured execution are critical. My background sits at the intersection of project leadership
    and marketing & communications — a rare combination that ensures change doesn't just get signed off, but
    actually sticks. I don't develop integration strategies — I make them work. As an interim project lead, I step in
    when the plan is ready and drive the execution: holding the threads together across teams, timelines and
    stakeholders.
