Linda Nelson

Managing Director
Linda Nelson has been the Managing Director of MELISA since 2005. After witnessing how MELISA testing has helped patients recover from chronic illnesses, she has made it her aim to raise awareness of how metals can induce serious health problems in sensitive individuals. She does this by: encouraging and enabling research, working with licensed MELISA laboratories to develop new applications for testing and by organising international conferences.

Mrs Dutton’s personal experience with mercury-induced ill-health encouraged her to collate scientific evidence on the effect of mercury on health. At the same time, she set up a patient support group to offer advice and guidance to others with similar symptoms. She is particularly interested in the role of mercury in the development of scoliosis.
