A professional mediator since 1998, he brings a unique scientific perspective to the table. During his hydrogeologic consulting years, Mr. Cerrillo developed his mediation/facilitation skills while serving as a project and office manager for groundwater and environmental firms. On both national and international projects he dealt effectively with multi-discipline, multi-cultural personnel, clients, and government entities.
A few examples of Mr. Cerrillo’s ability to bring resolution to projects that were in conflict include:
- A major groundwater development project in Puerto Rico for large petro-chemical companies was stuttering along with different project coordinators causing an increase in the time and cost of completion. Cultural differences between coordinators and contractors were the main problem. Mr. Cerrillo, working closely with local contractors, got the work completed on schedule and enabled the firm to obtain additional work.
- A consulting firm working on coal mining and groundwater issues was being challenged by a coal company of not delivering. Mr. Cerrillo successfully negotiated between the owner of the consulting firm and the mine manager to resolve issues and obtain additional work for the consulting firm.
- A $13 million dollar groundwater development project in Somalia East Africa was two years along when conflict amongst the various teams broke out and work was at a standstill. Mr. Cerrillo was hired as team leader to reinvigorate the teams and get the project completed. Work was accomplished within the time constraints of the project, including the preparation of a 6-volume report to USAID.
