Mel Kasting is a clinical herbalist, instructor and Clinic Director for the Eclectic School of Herbal Medicine’s student-led free clinic located in Lowgap, North Carolina. As the Clinic Director of a student-led clinic in a rigorous full-time clinical training program, she is uniquely qualified to support the beginning herbalist in their journey towards professional herbalism. Mel spends most of my time sitting in with student practitioners, reviewing their cases, and helping them to develop the skills necessary to become successful clinical practitioners. Mel is trained in functional herbalism, a modality that blends traditional western herbalism with clinical nutrition and functional medicine. It is a systems-based model that honors traditional plant-based care, while recognizing the importance of lifestyle modifications, herbs, and supplements, alongside functional laboratory testing, to address the whole person rather than an isolated set of symptoms or disease. She works with many types of illness, acute and chronic, and specializes in mast cell disorders, autoimmunity, chronic stress, and trauma. She offers mentorship in foundational clinical skills, functional bloodwork assessment, SOAP note writing, case review, physical assessment, clinical nutrition, and building treatment protocols blending traditional western energetics with the above skills. I am also available for beginning students to help coordinate effective self-study programs. Mentorship Price is $50 an hour, with one 3-hour need-based scholarship available every 3 months.Some Work/Trade available, distance and in-person. I also offer long-term mentorship packages tailored to your needs, as well as individual case review and a limited number of short-term, in-person apprenticeships on my shared land in Smith River, VA. Plants are magic and so are the people who connect with them!

Don Ollsin, MA, RH (AHG)

Email: don@grassrootsherbalism.com

I am an herbal elder. I have been studying, teaching, wildcrafting, making medicine, healing, consulting, herbal politicking, and running clinics, dispensaries and retail outlets since 1970.

I recently completed a Masters degree in Environmental Education and Communication to help serve my students and the planet better. I have also trained with Indian mystics and Native elders. I teach modern and traditional systems of healing. I no longer see a fragmented disassociated body or world. Physiologically, I no longer see the body as made up of separate systems, but rather as a matrix, the extracellular matrix. I see the earth, water, sun and sky as sentient beings, along with all the other forms, such as rocks, plants, animals and humans.

I teach and practice "sentient openness". I see herbs as my friends and companions, not as biochemical factories here to serve me. Herbs can heal you just by being in their presence alone.

Herbs are light eaters and heal through the transmission of light. I teach students and clients to find their herbal allies. When we visit the ginkgo tree, I remind my students that six ginkgo trees survived at the epicenter of the atomic bomb at Hiroshima and are still alive today. Now that could be an ally.

I wish to share my teachings, from the traditional systems like grassroots herbalism, shamanism, and Ayurveda, to the modern, like the extracellular matrix, the zero point field, and the biology of perception.

I can speed your journey by guiding you to the right sources for each level of learning. Being an elder, I can provide and/or guide you to the knowledge that you need to become a proficient healer.

I want to train as many young herbalists as I can and get those that want to be recognized as Registered Herbalists by the AHG. I support and believe in the AHG, as I was part of the original crew of herbalists who dreamed of such an organization at Breitenbush Hot Springs so many years ago.

Mentoring provides the magic of individual support and the guidance that distinguishes information from education in the first place. Together, we will establish checkpoints to measure how you are reaching your goals, through both group check-ins and individual accountability.

All applicants are required to complete our Foundational Course before applying for the mentorship program. https://grassrootsherbalism.com/course-3

Katolen Yardley, MNIMH, RH (AHG)

Email: info@katolenyardley.com
Mentorship Type: Virtual/Remote, In Person

My introduction to herbal medicine began years ago when I discovered my grandmother enjoyed making dandelion wine. It has been a long meandering journey since that time. I am a Doctor of  Osteopathy and my herbal educational background has been completed from the School of Phytotherapy (UK), Dominion Herbal College (Canada), Wild Rose College of Natural Healing (Canada) and Iridology training (NIRA). I completed my formal training in 1999 and have been in private practice since that time in Vancouver and Port Moody, BC. Some of my own mentors through my journey in herbal medicine have been the late Christopher Hedley (UK), Chanchal Cabrera (Canada), and Rowan Hamilton (UK). Currently,  I am the current president of the Canadian Herbalist's Association of BC (CHA of BC)  - from 2013-2019 and the president of the Canadian Council of Herbalist Associations (CCHA) from 2017-2023. I have also had experience in scope of practice, ethics and legal issues in Canada. I am familiar with quality control and GMP practices pertaining to formulations.

I have been running a student clinic mentorship program since 2010 and have guided numerous students through their supervised training clinics and into professional membership of governing associations. Since 2012, I have been a clinic supervisor at the Dominion Herbal College student clinic –and instructor in their 4 year Clinical Herbal Therapy Program. I am adjunct faculty at Boucher Naturopathic Institute where I have been teaching botanical medicine and hands on medicine making since 2008. A natural health product formulator and contractor, for many years I ran a busy wellness center in downtown Vancouver with 15 practitioners; thus have had much experience with marketing and business management. For many years I was the dispensary manager at a busy local herb shop, Gaia Garden Herbal Dispensary in Vancouver, where I oversaw the compounding and formulations of products, quality control and good manufacturing policies. In the summer I teach herbal medicine classes at Van Dusen Botanical Gardens and UBC Farms - do check out their class listings.

From 2000-20015, I appeared monthly on Global Televisions Morning News offering herbal medicine information to the public. This news segment was syndicated across Canada. I have written textbooks for the Canadian College of Natural Nutrition (2011) and in 2016 I published my first book: The Good Living Guide to Natural and Herbal Remedies (Skyhorse Publishing, 2016) a medicine making book with recipes, color photographs, and monographs of 49 medicinal plants.

I have been trained in western herbal medicine and the bio medical area of herbalism. My area of specialty include women's health, (fertility, cervical dysplasia, menopause), skin disorders and digestive dis-ease. My prior university training was in Psychology, thus I also have a strong interest in the mind body connection and emotional component to dis-ease. I have created numerous program curriculums for Langara College including a Holistic Approach to ADHD and am currently teaching in the Strategic Resiliency Program for First Responders: A holistic and herbal medicine approach to trauma (PTSD). I teach at various herbal medicine conferences around the west coast each year. Personally, I find relaxation in yoga and running. I love photography, travelling to distant lands and learning from local elders.

My goal as a mentor is to assist you in gaining confidence in your practice. I can tailor our time to what skills you need most. I offer a couple options for mentorship:

  1. A supervised student training clinic where a group of students (and myself) meet monthly online and

  2. A week long in person intensives in a group environment located in Vancouver BC, Canada.

  3. One on one distance mentorship options for professional quantum leaps, applications for membership into association, business coaching.

For the online supervised student training clinic- students have the opportunity to take clients and learn the art of case history taking, product formulation and putting together a comprehensive health program. Health related topics, deep dive discussions and theory are covered each week and students learn together in a group environment.  The cost is $ 16 per hour.

Frequently during the year, I hold a 1 week-in-person student training clinic allowing for students or new practitioners the opportunity to gain skills in a clinic environment, learning among one's peers. Apprenticing is a valuable experiential form of education providing a bridge for students to complete their formal education and prepare for clinical practice.  Training will be provided for physical assessment skills, blood pressure taking and other hands on assessment techniques in addition to learning about dispensing, herbal medicine formulation and other skills related to clinical practice.

During this training time you have the ability to observe an experienced practitioner or senior students take case histories and clients, and develop your own skills with case history taking, record keeping and follow up consultations, create health protocols including nutritional and lifestyle advice, herbal medicine, essential oils and topical application of herbs. This is an opportunity to hone ones formulation skills, fine tune ones counseling techniques and gain compounding experience. Patients vary depending upon the week and can occur in person or via phone.

One on one mentoring can be done via phone or skype on a twice per month schedule (with some email follow up). My rate is $ 100 per hour - available in 5 or 10 sessions. Sorry no trades. Mentoring can be combined with in-person student clinic training.

Many students seek the guidance of a mentor in a clinic environment to become confident, skilled practitioners while completing their student clinic training hours in order to apply for professional membership in with the AHG or BCHA, OHG, AHA or other professional association. Typically a combination of one on one mentorship in addition to group learning would be ideal for candidates wanting to complete their applications for professional membership.
