Our people

Tomo Thompson, Chief Executive

Tomo has a deep interest in people, place and nature. When not at his desk he is often found walking, running, climbing, cycling, dog-walking, or photographing his way round countryside, hills and mountains near and far. A retired Army Officer, he also teaches outdoor pursuits, is a volunteer countryside warden, and a volunteer member of the local mountain rescue team.

Tony Wallace, Planning Officer

Tony Wallace has been an RTPI chartered planner for 15 years and has worked across five different English counties in both development management and local plans. He works for the charity part time providing planning advice. He lives in a village between the city of Sheffield and the Peak District National Park and regularly drags his young family out for long walks in the Dark or White Peak. He spends what is left of his free time rescuing people having volunteered with a local mountain rescue team for over ten years, and also if at all possible by trying to enjoy himself in the relative peace of the countryside, walking, fell running, climbing, kayaking and swimming.

Katrina Pigott, Finance and Office Manager

Katrina joined us in August 2026 as a part-time Finance & Office Manager and has a solid background in office management and bookkeeping.  She was looking to join a small team of people who are passionate about what they do so CPRE PDSY fitted that perfectly!

Living in Sheffield, she has always felt very lucky to have the Peak District as well as many beautiful parks and green spaces on her doorstep and enjoys spending time outdoors, particularly walking.

“These places are important to me for their beauty, wildlife and the opportunities they provide to enjoy nature, and I want to see them protected and cared for for future generations.”
