Denise Joswiak

During her 37 year career as a nurse at Allina Health, Denise enjoyed educating, teaching Transformative Nurse Training, Infant Massage, Stress Reduction, Aromatherapy and other classes involving self-care and integrative therapies. It was her passion for integrating holistic practices that led her to create the Aromatherapy Program for Allina Health. After the creation of this program, she co-authored articles presenting research validating the legitimacy of clinical aromatherapy. She has since spoken internationally about the effectiveness of this program, and the importance of holistic care.

  • 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 of good quality. 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 facebook group and group Zoom meetings where we will discuss elements of the program and share case study recipes and results. You will be studying as part of our Essential Health Community.
