Marianne primarily offers expertise in:

  • Diversity, Equity and Inclusion
Experience

I have led several successful leadership and organizational transformations, partly through my work as a strategic management consultant. Also, in my current role and previous positions as CEO, as well as leadership roles at the corporate level in HR. I have also served as the Head of Diversity & Inclusion for several years. I am the author of the book “Gid vi gad” (“If only we would – on the path to equality, diversity, and inclusion”). I find it meaningful supporting leaders and organizations on the D&I agenda. I believe that the key to healthy organizations and a sustainable future lies in understanding and harnessing the strength of diversity and inclusion. By daring to listen to different viewpoints from diverse stakeholders, we gear ourselves for success. Throughout my career, I have participated in various boards. Currently, I am a board member in Danish Industry Management advisors. My top priority is to ensure the continuous success of Mannaz – for the benefit of the numerous people and organizations we serve and collaborate with. This extends to the respect I hold for our employees, associates, and partners whose efforts each day make a positive difference.

Diversity, Equity and Inclusion The inclusive workplace promotes mental health and delivers a better bottom line

Companies that focus on inclusion and psychological safety experience fewer sick days, higher engagement, and better results. Data shows that for every DKK invested in mental health, there’s a return on investment of five to six DKK. Inclusion isn’t just a value — it’s a proven business strategy. So, what can you do today to create more well-being around you?

Diversitet & Inklusion Den inkluderende arbejdsplads kvitterer med mental sundhed og bedre bundlinje

Virksomheder med fokus på inklusion og psykologisk tryghed oplever færre sygedage, højere engagement og bedre resultater. Data viser, at for hver krone investeret i mental sundhed kommer fem til seks kroner igen. Inklusion er ikke blot en værdi – det er en forretningsstrategi med dokumenteret effekt. Hvad kan du selv gøre i dag for at skabe mere trivsel omkring dig?

Diversitet & Inklusion Stærkt partnerskab sætter fokus på ledelse, diversitet og mental sundhed

Mannaz styrker det strategiske partnerskab med Goodtalks for at fremme positive forandringer på danske arbejdspladser. Vores fælles mission er at støtte ledere i at skabe inkluderende og robuste arbejdspladser, så de kan navigere dygtigt og effektivt trods modstand. Tidens lederskab handler om at gøre en langsigtet, positiv forskel – både for ’people, planet & profit.’
