After researching online, when I came across Essence of Thyme, I immediately enrolled in the Aromatherapy Practioner Program. The wealth of knowledge I am gaining is incredible! This is not like most online programs I have taken, as the instructors are always there to answer, guide, and support.

Colleen and Kelly are an amazing team that wants to see students succeed.
Their wealth of knowledge and student is incredible.

I am proud to be part of this school and love the fact it's Canadian. I have now gained the confidence to use essential oils safely and to help others thanks to Essence of Thyme.

Essence of Thyme’s mission is to maintain its gold-standard in aromatherapy education and to move the industry forward by training highly qualified aromatherapists to master and represent the profession.

Our vision is to embrace and elevate the many facets of aromatherapy through personable and high-quality education, grassroots initiatives, and to spread global awareness of the many benefits aromatherapy has to offer.

Essence of Thyme is a fantastic school and the advanced aromatherapy course has a lot to offer! I have learned so much amazing educational information while taking this course as well as had lots of hands-on experience. The instructors are amazing and get back to you quickly when needed. They also have a lot of resources online in the student login and are very thorough! I have enjoyed working with the instructors while taking this course and I highly recommend it to anyone that is serious about their aromatherapy education! 

Essence of Thyme is unique because as we keep our students up to date in the field and maintain our program recognition at the highest levels, we always make time to give each student our personal attention.

Further, we work on the ground and with our students to help protect threatened oil-bearing plant species – these beloved plants are the foundation of this field and should also be healed, as we use them for our healing.

More About Kelly 

Registered Aromatherapist (RA®)
Essential Oil Therapist (EOT®)

Kelly holds a Doctorate in Biology, an MSc in Conservation, a BSc in Biology (cum laude), and is a certified aromatherapist. As founder and Executive Director of Airmid Institute, she is dedicated to the global education, research, and conservation of aromatic medicinal plants, and to helping to protect and promote uses of traditional medicine in Indigenous communities. She has conducted research in conservation biology, molecular genetics, chemical ecology, behavioural ecology, and ethnobotany. 

Her work has been highlighted by Canadian Geographic, the British Broadcasting Company (BBC), and published in numerous peer-reviewed journals. She identified traditional uses of 60+ aromatic medicinal plants across northern, central, and southern Peru, worked to help protect threatened slow and slender lorises, reported on the ingenuity of tool use by threatened orangutans, and made a novel discovery of how small wasps rely on individual chemical signatures to mediate their mating ritual.  

She speaks worldwide about the conservation and sustainable management of essential and carrier oil-bearing plants and shares her ongoing work in Peru with the Shipibo on the development and implementation of the Toucan Project (named after the tropical bird which, apart from its bright colors, is known for dispersing endangered rosewood (Aniba rosaeodora) seeds).  

Kelly volunteers as a Community Scientist for Science World (Vancouver, BC), and founded the Vancouver Community College Urban Apothecary Learning Garden – an educational venue for at-risk youth and culturally-diverse students.  Kelly served a decade on the Board of the British Columbia Alliance of Aromatherapy (BCAOA) and was honored with the BCAOA 2016 Achievement of Excellence Award. She currently sits on the Board of the United Plant Savers.

"The monthly lectures, student FB page, and student forum are filled with detailed and relevant pieces of information. You can get what you need in the moment and come back to digest the rest at later times.

I highly recommend EOT to anyone wanting to further their aromatherapy education. Colleen and Kelly are gentle and caring instructors who provide amazing support. The moment you hear yourself explaining a concept, essential oil, or caution to someone, those are the moments you savor! You know you have grasped information when you are able to share it. EOT will have you sharing your new-found knowledge with all who will listen!"
