About Our Team

As the Director of Ecolibria and a lecturer for 12 years in the Building Biology field, I have identified who I felt were some of the very best and most promising students graduating with the Australian Nationally Accredited Advanced Diploma in Building Biology.

After graduating I have then personally conducted further on site training and assisted our team members in the various states so that they utilise best practise in all the assessments that we conduct.

All reports compiled by the Building Biologists in the various states are then checked and clarified by myself as well as our report editor here in the Head Office in Victoria.

Any areas requiring clarification are personally discussed with the Building Biologist who conducted the assessment and a final report that has been read and discussed by three individuals is then submitted to the client.

This process, to the best of our ability ensures that a thorough report is completed with discussion between Building Biologists taking place (if required) in relation to all aspects of the assessment and test results.
