Mily nielsen
Office Manager

With over fifteen years' experience as an administration professional, Mily has worked closely with Directors and CEOs across a number of sectors and this has honed her radar for what makes a good leader great.


Mily has been fortunate to work with some truly inspirational leaders in the past, be it direct report, dotted line or general association, and can often be found quoting the words of a former boss or mentor. This makes her the perfect fit for LeadersHP. Not least because she loves a good quote. She truly understands the work we do with leaders and why it makes such a difference.


When not offering morsels of wisdom, Mily enjoys spending time with her daughter, Asta, or reading epic fantasy novels.
