Troubleshooting early



The firm was created in 1995 by Marisa Guitart, an international executive in the life sciences and medical devices sectors , based on a history of collaborating with internal teams to project manage change and drive business growth. She is joined by consultants who bring specialist skills in areas such as business strategy, sales and marketing,  communications and PR, corporate finance, and property and facilities management, as well as project management experience in other sectors.


We differ from some large, multi-sector consultancies in that we can offer an external perspective that also leverages previous management experience. We always provide our clients with the skills and resources we promise. And our main objective is to achieve the best results in the shortest possible time frame.


This approach has led to long-lasting relationships with firms such as Amersham Biosciences, Pharmacia Biotech, Pharmacia Diagnostics, Phadia and Bayer Healthcare, as well as SME’s and start ups in a range of other sectors.


Our team comprises people who know and love what they do. As a result, we demonstrate complete engagement and a driving passion for each and every project we become involved with.



Marisa is an international management executive and project director who has mainly specialised in the life sciences and medical devices sectors for more than 30 years. She has assumed senior management responsibilities in several functional areas and managed projects involving organisational change, process reengineering, cost improvement, IT systems and corporate restructuring.


A key strength is her ability to analyse situations, identify solutions and help lead teams to achieve results beyond their expectations. She is well positioned to assist executives seeking advice on change management, improving business focus and integration, improving profitability, reducing operating costs, or problem-solving, and to take on the high level planning and implementation of complex restructuring and reengineering challenges, start ups and spin offs, as well as technical projects.
