"I researched schools and I could not find a school that exceeded or even matched Essence of Thyme. Essence of Thyme allows for students to work at their own pace, and this was very important to me as a single parent with a full-time job. 

I was shocked at how extensive the program was, and I felt completely out of my element and over my head, but Colleen and Kelly give you the support and opportunities to succeed in this program. You learn, not only from their expertise, but also from a wide variety of experts in this field of study. This course will exceed your expectations!"

"I always had a passion for Holistic health, and it was important to me to have the proper education on essential oils and how to use them safely. The communication between instructors and students is phenomenal, by far the best I’ve personally experienced. The instructors encourage and support questions and comments. My experience with EOT has been amazing.
They’re compassionate, knowledgeable, informative, and again the communication has always been fantastic.
If you’re deciding on which online course to take, I highly recommend this one!"
