“It is the spirit of the plant, that heals the disease. The plant chemical merely gives it a form in which to travel.”
Stephen Harrod Buhner
Private Classes available anytime. Contact me above.
You will learn so much more than what you expect you might. There is so much more to the essences than the way they smell. It is much deeper than that. This class has the potential to change the way you think about everything.
If you are looking to open your heart, mind and body to the amazing wonders of trees and plants and learn to explore more, this class is wonderful!
It was very interesting to see, touch, smell all the different essential oils. I loved how the class explained the whole process with the essences from beginning to end!

Sheridan has been the most wonderful teacher for me and my level of understanding plants and energies. She never made me feel I was asking a lame question, nor did I feel uneducated in her presence. Sheridan’s energy is the perfect compliment to the essences and Wisdom of the Earth’s philosophy. I only hope all of their students are fortunate to have such a special, loving, super educated and open teacher.
I loved each second of the class. Sheridan is a great teacher and all the subjects were so interesting I just wanted to learn more and more .
Level 1 Certification Requirements
To receive certification, you must write a 5-page paper (double spaced) on an essence of your choice. You have 3 months from the date of the class to submit the paper… but we strongly recommend that you not take that long. We’ll discuss this in detail during the class, but it is like a journal entry of your personal experience, not a college research paper.
$50 Certification Fee is due when you submit your paper. Once you have submitted your paper, you are eligible for Wholesale Distributor pricing on Wisdom of the Earth essences, a 22% discount off the practitioner price. Also, you are entitled to audit future Level 1 seminars (space permitting) at no cost, but you MUST register to do so.
I think the Zoom platform is an effective way to teach. As a busy mom of 2 kids, it was so helpful for me to be able to attend from home and not spend time traveling to and from a location. It was much less stressful for me each day.
I really enjoyed the online format. I liked that the material was broken down into 3 hour sections as it allowed me the time to really open up to and work with each essence individually.
I always say that the earth saved me.
In fact, I believe it can save just about anyone, no matter what they’re going through. Growing up in Aspen, Colorado led me discover my love for the outdoors and how the human body is healed by nature. I learned firsthand the healing power of the earth as a young child hiking in the mountains to be with the trees as I recovered from trauma. My connection to the land has carried me through the most challenging times in my life.
Helping others in a deep, meaningful way to use the medicine of the earth to heal themselves has always been my calling.
As a child, time and time again, I was surprised by the ways that natural medicine could cure ailments in ways modern medicine just wasn’t able to do. My passion is teaching you to trust yourself and listen to your inner wisdom and knowing to heal yourself, coupled with the consciousness of the plants to support you.
My mission is to empower you to take your health into your own very capable hands.
Connecting with the essences of the plants and trees is the best tool for self-healing I have found. I know that working with these essences offers you healing on every level – physically, emotionally and spiritually.
Bio
By trade, I am an Alchemical Astrologer, Spiritual Aromatherapist, Holistic Health Practitioner (HHP), Clinical Aromatherapist (CCA), and Certified Nutritionist (CNC). I have worked in the holistic health field for 20 years and came to the power of aromatherapy through a traditional naturopath with whom I apprenticed 10+ years ago. My practice is based in Aspen where I embody the local motto of mind, body spirit in my healing work with clients. I work with people locally and all over the world, as well as teach ongoing classes on astrology and aromatherapy.

Sheridan is so warm and welcoming and has so much knowledge to share. The format, order, handouts, discussion, questions and answers, personal knowledge, and everything else makes this one of the best classes ever!
