Hawthorne's ownership comes from medicine — the most regulated profession in the UK. In that world, ethics are not a company value on a wall. They are a condition of practice.
In December 2024, that ownership team acquired SSY Group and rebuilt it as Hawthorne. The client relationships built over two decades were worth protecting. The standards behind them were not. So we replaced the standards, rebuilt the team, and kept the clients.
