What Georgina says about Gillian: When Gillian expressed an interest in joining our relatively new firm as a consultant I was both humbled and blown away. She is a hugely respected and well-known name in the industry and has joined us from a top tier firm. She brings with her invaluable experience which the whole team will benefit from, and we are all delighted to support her in her next chapter of her already exceptionally successful career. Clients love her, opponents respect her and her work in the charitable sector is inspirational. So, I look forward to supporting her in that too.
