MSEI MultiSciences Expertises Inc.

is the culmination of a lengthy process of reflection of scientific experts from different fields.

These individuals accumulated nearly two centuries of experience in the various fields of activities in which MSEI operates.

The diverse needs of an increasingly demanding clientele, for the legal sector, the insurance world and the scientific research field, have led MSEI to redefine its approach towards its customers, within the framework of its expertise.

Thus, each mandate is a specific case adapted to the needs of the clientele and oriented towards the objectives defined by the client in collaboration with his expert.

MSEI relies on this ongoing Client-Expert interaction to ensure that a file is more than just a mandate.

MSEI is established in the Montréal and Québec City regions and covers the entire Province of Québec territory, as well as its bordering regions.

The company

MSEI was founded in 2006 by a group of experts highly qualified in the environmental, chemistry and engineering domains. Its goal is to produce high-level scientific and technical expert assessments which rigorously respond to clients’ expectations, principally from the insurance, legal and industrial sectors.

MSEI experts establish the origin and cause of losses.

Always assisted by their support personnel, MSEI experts work individually or in collaboration to find “the” appropriate answer to each of their client’s queries, demanding a scientific solution, for an efficient resolution to each file.

At MSEI, we wish to develop and to maintain a long-term relationship with our clientele. We strongly believe that this way favors a win–win partnership… with you, our clients.
