She has trained over twenty facilitators in Western Australia, Tasmania and Melbourne and was the first resources distributor in Australia.

Testimonial from Personality Dimensions® Author

“I was most impressed that Cecile sought me out as the primary researcher and author of Personality Dimensions and traveled from Australia to Canada to take her Level II Facilitator Trainer Certification from me directly. I later discovered that this is just typical of the drive, determination and professionalism Cecile has for her work. She has since be awarded the status of Master Trainer by the publisher of Personality Dimensions…….a rare honour.  This is not a course but rather an “appointment” for extraordinary work with PD.

Cecile has been in contact with me over the years to seek advice and counsel, but I now find that it is I that can now learn from her.

She is committed to her client groups and provides quality service and follow-up to everyone she trains. As a professional coach or trainer, if you are looking to add an effective, versatile tool to your professional toolkit, I would recommend getting Personality Dimensions Certification Training from Cecile”.

Lynda McKim, author, Personality Dimensions.
