  • Why should I become Certified?

    To deepen your understanding and to gain a strong scientific foundation regarding aromatherapy. To comfortably and confidently discuss the science of essential oils with others. Certification gives you the credibility to use aromatherapy professionally.

  • Are there any prerequisites for the course?

    No, anyone and everyone can take this course.

  • Do I need to have essential oils to take this class?

    In this program, we study 47 essential oils. You do not need all 47, but you will need to have a selection. Your essential oils must have batch-specific gas chromatography/mass spectrometry (GC/MS) reports. That’s how we study chemistry and know the oils are pure and unadulterated. If you have questions about your oils or which oils to purchase, we will be happy to talk with you and/or provide several essential oil company options upon registration. (We do not profit from our recommendations.)

  • Are there any other supplies that I will need?

    As part of the ACP, you will be doing 10 case studies and 12 blends. You will need a few containers and carriers. In your welcome letter, we will outline exactly what you need. In addition, we look at Tisserand & Young (2014) for some of our safety information. It is a great reference to have on hand. It is available for purchase, rent, and as an e-book.

  • Is there interaction with an instructor or other students during this course?

    Prior to beginning the program, you will have a personal Zoom meeting with Denise to discuss your goals, timeline, and details of the course. You may connect with Denise as needed via email, phone, or by Zoom throughout the program. You will also have access to a private community page and course specific student discussions where we will discuss elements of the program, share case studies, and talk about what is going on in the world of aromatherapy. You will be studying as part of our Essential Health Community.

  • When can I start, and how long does this program take?

    You can start anytime! This is a learner-paced program, meaning you can move through the material as quickly as you would like, or take as long as you need. Students have finished in six weeks, and taken up to 1½ years. The average length of time is five to six months.

  • Do you offer in person certification?

    Yes! They are currently on hold due to covid, but we teach through Minneapolis College, at our Mendota Heights location, and Denise is willing to travel to teach groups upon request.

  • Do you offer a payment plan?

    Yes! Choose to pay your tuition in full, or in five or ten automatic monthly payments.
