Denise has created a thoughtful and caring space for students to take in the wealth of knowledge that she possesses. Her teaching style makes the information accessible to multiple learning styles and levels of previous knowledge. I would highly recommend any of her offerings, especially the certification program.

Vicky Grossman

Massage Therapist - Allina Hospice

Denise’s passion for aromatherapy/essential oils and the many ways to use them medicinally is what makes this class so worthwhile!! It’s essential oils from the ground up - everything I needed to know to confidently incorporate their use into my practice.

Nikki Kirchner

BSN, RN, CNRN, CRRN, SCRN, CA

In Denise’s class, there is no judgment. It didn’t matter who you were, what your background was, we were all at a level playing field and there to learn, help, inspire and create. As a left brained person with right brain tendencies, one of the most surprising things I learned, was that aromatherapy is based on science, history and perhaps a bit of the “as of yet unknown”. What has embedded itself in me, is the “blending” (pun intended) of art and science to facilitate well-being and even healing in fellow humans in a creative, practical, meaningful (and affordable) way. This class has forever changed, motivated and inspired me.

Emily Jo Fristed

BA, Licensed Massage Therapist, Lead End-of-Life Doula, Certified Clinical Aromatherapist, Reiki Master

This is a comprehensive certification course which made me feel confident to apply aromatherapy services in the medical field. The format is easy to follow and the material is exceptional. I highly recommend the Aromatherapy Certification Program.


  • 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.

  • Can I get reimbursed for this program?

    Many of our healthcare professional students have received reimbursement for this program as they receive CEs or CNEs as massage therapists or nurses. If reimbursement is an option for you, please email and we will make certain you have all of the required information.

  • Do you offer a payment plan?

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