James Whitmarsh - Operations Director

James began his career at a young age, gaining invaluable experience across various sectors of the automotive industry. This early exposure helped him build a solid foundation in business operations and gave him a comprehensive understanding of what makes a company thrive. Drawing on these skills, James later ventured out on his own to start his own business. His Garden Design and Landscaping company continues to flourish to this day, a testament to his expertise and entrepreneurial spirit.

While James is always willing to tackle new challenges, he’ll readily admit that cushions and curtains aren’t exactly his specialty.

His ability to handle the less glamorous but crucial tasks ensures that everything runs smoothly, supporting the team and clients alike.

Outside of work, James has a wide range of interests. He’s passionate about health and fitness, enjoys DJing, and finds relaxation in fishing and hiking. His varied hobbies reflect his active, well-rounded approach to life.
