“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 began searching for schools and after a lot of research decided on Essence of Thyme College of Holistic Studies and I am so glad that I did! I wanted to learn how to use the oils properly for myself, my family and friends. Colleen is an amazing and attentive instructor and now she has joined forces with Kelly. The two of them are incredibly knowledgeable and have a lot to offer. I highly recommend this course for anyone looking to pursue a career in aromatherapy, or like me, to learn everything they can about those magical little bottles of essential oils.”

You'll have hands-on support from our founders, Colleen and Kelly, who have decades of combined experience in education, research, sustainability, and the business of aromatherapy.
Colleen Thompson, RA, MIFPA
FOUNDER
After 20 years in the field of banking, Colleen was completely transformed by the pain-relieving effect essential oils had on her chronic migraines.
Since that “aromatic” moment in 1995, she began her journey in the field of Aromatherapy and has been a Registered Aromatherapist since 1997.
She incorporated her business, Essence of Thyme Ltd., in 1995, and over the course of 12 years owned three aromatherapy stores and a holistic spa. In 2012, she completed the development of her Aromatherapy Certification Program which is offered through Essence of Thyme College of Holistic Studies.
Colleen’s practical experience of owning and operating aromatherapy stores, creating blends for the stores, as well as providing aromatherapy courses and workshops and various aromatherapy massages and complementary treatments is reflected in the program.
Kelly Ablard, PhD, RA, MIFPA
CO-PRINCIPAL
Kelly stumbled upon essential oils early on in life and was amazed by their beautiful fragrances and healing benefits. But it wasn’t until years later when she was working on her doctorate degree in biology in 2007 that Kelly was inspired to become a registered aromatherapist. It was then that she witnessed the astonishing connection between essential oil compounds and their use in communication by many species on the planet.
As a Conservation Aromatherapist™, this knowledge continues to help her protect threatened animal and essential oil-bearing plant species, which in addition to aromatherapy, is one of Kelly’s key areas of expertise.
Kelly is a certified and registered aromatherapist and holds a PhD in Biology and an MSc in Conservation. She currently conducts research in Peru on the Endangered rosewood (Aniba rosaeodora) tree. Please click here for her CV.
