After researching online, when I came across Essence of Thyme, I immediately enrolled in the Aromatherapy Practitioner 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 support 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 the Gold Standard for aromatherapy education, moving the industry forward by training highly qualified aromatherapists to master and represent the profession.

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

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.

"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!"
