Sahara Fleetwood-Beresford

Marketing & Comms

Sahara’s background is in marketing. She specialises in digital media and content creation.

She runs the charity’s social media accounts and offers her marketing expertise.

She was diagnosed with Ulcerative Colitis in 2007. She’s battled 7 surgeries, multiple treatments and complications, extra-intestinal manifestations and the mental effects of IBD since. She now lives with her 3rd ileostomy which is a permanent fixture, after a failed Jpouch. All have played a part in Sahara’s decision to raise awareness, fundraise and offer support to other IBD sufferers.

Sahara was awarded ITV Central’s ‘Pride of Britain Fundraiser Award’ in 2015.

In her spare time, Sahara runs #IBDSuperHeroes (awareness and support), and writes an IBD and ostomy blog.

Her passion for raising awareness in the hope of finding a cure with the help of research funded by Cure Crohn’s Colitis never wavers.

Danielle Blance

Treasurer

Danielle was approached by Gilad in 2021 to take up the position as the treasurer. Danielle is currently undergoing tests for Crohn’s so was keen to get on board with the charity.  Danielle works alongside Gilad at Linn Products Ltd in the Finance department and has 16 years’ experience in finance.

In her spare time, she enjoys spending time with her family and two young girls, weight training and enjoys attending football matches with her family.
