Deborah Holmes-Langstone

PA to Managing Director

Deborah joined Open Door Adventure in June 2019.  Her position is PA to Dave Orange and this has meant a welcome return to her secretarial roots, albeit she is new to the Outdoor Pursuits industry. Her previous career was in General Management, Business Development and Marketing.  She loves the fact that her new role presents her with challenge, but she no longer has the pressure and responsibility of management.

Deborah will be your first point of contact and she is happy to talk through the activities and services Open Door Adventure offers.

In her personal life, she enjoys getting away with her 2 dogs in her tourer caravan and when not away, she enjoys going for forest or beach walks with her “fur balls”.  She also enjoys interior design, refurbishing furniture into a shabby chic style, current affairs, gardening, reading and online Scrabble.

Mark Rogerson

Mark R

Senior Instructor

Mark joined Open Door Adventure in 2019.

After leaving the Army in 2003 and working on some of the largest civilian projects in the UK, Mark quickly realised there was more to life and embarked on a National Diploma in Sport & Outdoor Education.

After completing his education he moved to Yorkshire and quickly progressed to managing his own groups around the North of England.  He is an experienced Mountaineer and in 2011 completed a life goal by summiting Mont Blanc.

Mark has paddled and climbed all over the UK and looks forward to hopefully back to Europe.  He strongly believes in personal development and experiential learning.  His motto in life is “If you can’t do it, keep trying”.

Alan Jones

Alan J

Maintenance Engineer

Before becoming a member of staff, Alan used to do maintenance work for Open Door Adventure.  In 2016 and having proved his worth to Dave Orange, the Business Owner, he was offered a permanent contract of 3 days per week.  Alan has been a joiner since the age of 16, so has 50+ years of experience behind him.

Alan’s role is very mixed as you might expect!  One moment you may find him up on the roof, the next doing battle with one of the sash windows and then on a good day, sitting astride the ride-on mower and cutting the grass around the 25-acre site – which he particularly enjoys.

In his personal life, Alan is married to Gina; he has 1 child and 4 grandchildren.  Alan is particularly known for his love of grabbing bargain holidays and makes it his mission to have at least 2 a year.


Outdoor Pursuits Instructor

“Tose” joined Open Door Adventure in August 2021. Having studied for 2 years to become a Carpenter and Joiner, he decided against the profession planned since schooldays. Tose decided he wanted a real challenge and the challenge he wanted was a career in Outdoor Pursuits!

The trigger for this life-changing decision was when he did an abseil down St Asaph Cathedral at a Charity Event Open Door Adventure was supporting. Mark the Senior Instructor was leading the sessions and Connor was smitten with the adrenaline buzz.

Athletic by nature, Tose is now on his journey to become a fully qualified Outdoor Pursuits Instructor and has completed Archery Instructor Training and Paddle Sports, not to mention the hands-on support training since beginning at Open Door.

He aims to become proficient and expert as a Climbing Instructor and Mountain Leader, not to mention Paddle Sports and many more. Tose is delighted to have had the opportunity to join Open Door Adventure as a result of the Kickstart scheme and he’s very excited for the career journey that lies ahead of him.

Welcome to the team Tose and we wish you all the very best!


Outdoor Pursuits Instructor

“Sturdy” joined Open Door Adventure in August 2021 having seen a recruitment advert on Facebook.

Although new to the Outdoor Pursuits industry Sturdy has always been an “action man” and practising Kayaking, Sea Kayaking and Cycling. He spent a year travelling and for part of that time he cycled independently around the greater part of Europe. In addition to these activities, in his spare time he enjoys Orienteering, Wild Camping, Bushcraft and Climbing. His passion for travelling led to him acquiring an Adventure Campervan .. this now fills a good part of our car park when Sturdy is in work 😊!

Sturdy is delighted to be working in an environment that offers activities close to his heart but he’s also keen to help people grow and develop new and existing skills .. sometimes, skills they don’t even know they have.

Talking of skill building, already Sturdy has undertaken external training in the delivery of archery and in February and then a week’s Instructor training on Paddle Sports (not to mention the day to day internal training he’s been getting since day 1). Welcome aboard Sturdy and we wish you well!
