Katie Hepworth

I can wholeheartedly recommend Sian. She's a hugely experienced fundraiser, able to quickly build relationships and make a real difference, whatever the organisation. She's amazingly effective, a great team player and enormous fun to work with!

Cate Birch

I had the pleasure of working with Sian on a freelance basis during her time as Director of Fundraising and PR at Combat Stress. I was highly impressed by her energy, her high levels of achievement and constant ability to find the positive in every situation. I have also enjoyed crossing over with Sian on several other contracts and have consistently found her to be a great manager and colleague; when I took over from her on an interim contract she had established an excellent Trusts department with contented funders, effective systems in place and strong networks. I would not hesitate to work with Sian again.
