Krystian Overton-Arch (Forest School and Buschcraft Leader) Krystian started working at Acorn in early 2013 and now has 10 years experience in the sector. During his time as a nursery manager, Krystian experienced his nursery's forest school sessions with Gemma and Donna and decided he wanted to develop a career as a Forest School Leader and completed his L3 Certificate in Forest School Programme Leadership in March 2015. He also holds a L3 Childcare Qualification and is fully trained in safeguarding children and outdoor activity & paediatric first aid. Krystian has a keen interest in bushcraft and can often been found whittling sticks with his knife. In 2018, Krystian completed an Advanced Bushcraft Level 3 Award, which will help to expand Acorn's forest school offer, especially for older children.
