Student Testimonies


Thanks to the aromatherapy certification program, I gained strong knowledge in aromatherapy and built my self-confidence, self-responsibility and personal empowerment. I love attending the program and being part of the group during the entire program and want to continue being part of the community after I graduated.


Audrey Saint-Leger, Certified Level 1 Aromatherapist


I have taken many certification courses on aromatherapy but nothing compares to the Aromatherapy Certification Program by the Lorrie Hargis International School of Aromatherapy. I liked the material covered such as the safety in handling essential oils, precautions to be taken, ethical procedures, privacy of clients, as well as the excellent staff available to answer questions as they came up. I really enjoyed the continuing education, webinars, interaction with other aromatherapists, and valuable use of a library full of documents.


Betty Nieto, Certified Level 1 Aromatherapist


Thank you for the challenges you have made me face. I have learned so much more than I expected, and I have made new friends too. Level 1 was a great start and I cannot wait to start Level 2 now. An amazing teacher like you is hard to find and impossible to forget!
