Corporate, M&A, Interim GC & Compliance

Expertise

Jens Kellerhoff is a Partner at gunnercooke, advising domestic and international clients on all aspects of corporate law, with a particular focus on M&A transactions, corporate governance and compliance.

He combines top-tier private practice experience with extensive in-house and General Counsel-level expertise. This dual perspective enables him to provide advice that is not only legally robust but also commercially focused and practically implementable.

Jens acts as a trusted adviser to management teams and shareholders, particularly in complex, high-stakes situations where legal considerations are closely linked to strategic and operational decision-making. His work frequently involves cross-border transactions and governance matters involving German, US and UK stakeholders.

He brings significant experience from senior legal leadership roles, having led teams of varying sizes across multiple industries over many years. He has a strong understanding of the demands involved in managing legal and compliance functions within complex organisations.

In addition, Jens has substantial experience advising at board level and supporting governance structures, including roles equivalent to Company Secretary.
