Tara Diserens née Merison, Marketing Manager

Tara joined Sigmer in 2004 bringing with her over 13 years' marketing experience, covering B2B marketing as well as the computer games industry. At Sigmer, she is responsible for all marketing, PR and lead generation activities. She likes working in Sussex and loves cycling to work over the Downs, where she can indulge her passions of bird watching and plant spotting. Sometimes it's difficult combining this with getting to work on time, so she tries to keep them separate!  Outside of work, her interests include hiking, mountain biking, gardening and ornithology. Tara greatly dislikes litter in the countryside and supports the Stop the Drop campaign headed by Bill Bryson.

Prior to co-forming Sigmer in 1999, Niall spent a number of profitable years working within the Insurance Industry. He impressively secured a partnership deal with The Direct Insurance Group, and on the back of this accomplishment Niall went on to become the founder partner of the highly successful 'Ladies Direct'; the first female only motor insurance programme in the U.K.
