A whole new world!

I was totally new to aromatherapy; however, I’ve always loved flowers, plants, body care products, and perfumes. I never knew how those products were created or where essential oils came from. I enjoyed the course – it opened up a whole new world for me. I would recommend this course to friends, family, and associates. The course material is so valuable, it made learning exciting. I will never look at nature the same way; I can see clearly now!

I'm so inspired!

This experience was truly such an inspiration. What I loved most about the course was the wide range of references and visuals used as a collective curriculum. It is important as an educator to be able to have different types of references, such as articles, audio clips, visual aids, cheat sheets, etc., to ensure that your information is being received effectively. I am so grateful for this opportunity.
