Mark Buck is a pracademic, a practitioner who develops and tests ideas while doing the work those ideas are meant to explain. He writes about how organisations actually work, and in particular about the capable people who quietly hold weak systems together until the day they leave. Much of his work asks what allows a good result to survive the departure of the person who first produced it.
His first book, Leadership Without Arrival, begins with a deal that nearly didn’t complete. Its argument is that leadership done properly rarely produces a sense of arrival. It produces the next problem, often carrying the cost of the last solution. It was the first title published by Roebuck Publishing and is the first in a planned series on leadership, organisations and institutional capability. In its launch week in August 2026 it reached #1 Hot New Release on Amazon UK in HR & Personnel Management, Self-Employment and Small Business eBooks.
He is Chief Executive of GSI, a UK financial planning, wealth management and estate planning group, and Chief Operating Officer of Mitchell & Mitchell Asset Management, where he chairs the Investment Committee. Before financial services he spent more than twenty years in consulting, hotel and resort transactions and travel, including running what was then the largest private travel company in sub-Saharan Africa. His articles have appeared in FT Adviser, Money Marketing, Professional Adviser, The European Business Review and CFA UK’s Professional Investor.
He read Classics and German at Rhodes University and holds an MBA from Bond University. His writing through Roebuck Publishing is personal and doesn’t represent the views of GSI or Mitchell & Mitchell. When he isn’t running businesses or writing, he is usually reading history, philosophy or business, or being supervised by two Labradors who remain unconvinced by any of it.
