Specialises in



The commercial, corporate and M&A practice of Mazanti-Andersen is outstanding. We appreciate the collaboration greatly and find the practice both value-creating and solution-oriented. The venture capital team of Mazanti-Andersen is the best in town.

The team excelled in communicating with each other – always up to date on the M&A process, challenges, status, and ‘need to know’ for the specialist involved. All members of the team were professional, competent, and proactive in keeping a speedy process.
