Talal Al-Hamad

Talal Al-Hamad is a man of many talents. He is an herbalist with a diverse background in many natural healing modalities. He utilizes a unique east meets west approach to imbalances and disease, with great efficacy. He has been a student of various holistic modalities including Traditional Western Herbalism, ayurveda & Arabic Herbal Medicine, Homeopathy, Aromatherapy, flower essence therapy, yoga (pranayama, mudras & asana), and nutritional care.

His initial interest into holistic healing was due to several health issues that plagued him. Being completely dissatisfied with the answers and results allopathic medicine had to offer he set off on a personal transformative journey to seek out the true cause for his imbalances. This journey led to a period of deep study and personal growth as he foraged the plains of holistic healing to find his purpose. Without fail the path always led back to the power of nature, to the plants themselves. He loved the idea of not relying on anyone to manufacture his remedies (as homeopaths often do), and felt very empowered and connected with his own remedies. Their results were powerful and had little to no side effects. It was then he knew that herbal medicine was his path in life.

His formal education includes training at Dominion Herbal College and Chakrapani Ayurveda Institute (India). He also completed an intensive 2 year clinical herbalist diploma program, directly instructed by the past president of the Ontario Herbalist Association (2005-2015) Diane Kent. During these 2 years Talal gained much needed experience, working alongside Diane in her clinic treating a wide variety of clients.

Other instructors include:

-Michael Vertolli- Past Vice President of the Ontario Herbalists Association
-Nitin Shah – PHD Gujarat University – Ayurvedic Practitioner based in Toronto
-Carol Barber – CHT – Dominion Herbal College

In addition to his training, Talal has also spent many years of intense self study, immersing himself in the works of great herbalists such as: Michael Moore, David Hoffman, Donald Yance, Vasant Lad, Horatio C Wood Jr, Stephen Buhner, Ryan Drum and Nicholas Culpeper.

Talal is a Registered Herbalist and a professional member of The American Herbalists Guild (AHG) & The Ontario Herbalists Association (OHA). He works with people and animals & uses multiple modalities but is an herbalist at heart. His articles have been featured in magazines such as Ayurveda Mantra & Tonic Toronto.

Herbalist by day and jazz guitarist / fanatical foodie by night, Talal has an innate passion for healing and has devoted his life to developing his treatment protocols and furthering his knowledge of medicinal herbs. Having conquered his own health challenges with his knowledge, it is easy to see how his passion for healing others is truly sincere.

$50/hour for AHG student members, $80 for non-members.

Leslie Alexander, PhD, RH(AHG)

Owner of Restoration Herbs in Erie, PA, I work as a community herbalist. For me, herbalism brings together years of using herbs, a passion for the outdoors and my training in health-related research. My path to herbalism began in academia, fixed firmly in the Sciences. I received my B.Sc. from Fairleigh Dickinson University in Environmental Sciences and my Ph.D. from Heriot Watt University for my work with Enteromorpha, an intertidal seaweed. For several years I worked in England and Scotland as a research scientist, focusing on environmental factors affecting children's health. Drawn increasingly to more natural ways of healing, I decided to formally retrain as a medical herbalist and returned to the States in 2005.

After completing a diploma in herbal medicine and submitting my dissertation on turmeric in 2006, I began a three year clinical distance mentorship with Richard Mandelbaum RH(AHG), founding partner, director, and teacher at the ArborVitae School of Traditional Herbalism in New York City. Additionally, for many years my teachers have been those sharing their wisdom at symposia, published authors and the guardians of their works, online audio (and visual) lectures, workshops and, of course (!) the plants themselves. Each has shaped my thinking.

I've been an active General Member of the American Herbalist's Guild since 2004, a Registered Herbalist Member since 2009 and am serving my third term on the AHG Council. In addition, I teach clients, host public workshops on herbal medicine and medicine making and offer free monthly lunchtime herbal discussions - all of which are places to learn and explore herbs.

My interests encompass medicinal and culinary herbs, particularly herbs for the mouth (yes, the mouth!). My book, Dental Herbalism: Natural Therapies for the Mouth was published by Inner Traditions in 2014 and continues to draw a large readership. I can be found working online with Leslie Williams, offering a dynamic program in clinical skill development, for anyone with some herbal experience that wants to enhance and broaden their practitioner skills. I enjoy my canine pal, foods of all sorts, laughter and Tai Chi.

I am available for personalized in-person and distance learning programs, focused largely on western herbalism, assessment and protocol design; nutritional medicine; dispensing, formulating and medicine making; herbal pharmacy/cGMP issues and herb/drug/nutrient interaction as well as building a practice, legal issues pertinent to region/scope of practice, etc., and apothecary/office management. By all means please contact me and let’s discuss what your looking for and why. I look forward to hearing from you.

Matthew Alfs, RH (AHG)

Green greetings! I have been in general practice as a clinical herbalist since 1997 and it has been a real joy. In 2002, I achieved Registered Herbalist (RH) status with the AHG. Since 2003, I have served as the director of my own school of herbalism (the Midwest School of Herbal Studies), which has turned out many graduates─a number of whom have gone on to apply for RH status with the AHG. With that in mind, my goal as a mentor will be to help you to gain confidence in your herbal practice to the point where you feel (and are) qualified to apply for RH status with the AHG and to help you through that process. My mentoring rate is $55/hr and my preference is first for my own graduates as they wade into clinical practice and secondly for others who have achieved at least 2 years of formal education in herbalism from other schools and who have started seeing clients. Prospective mentees should also have acquired the AHG Handbook of Mentoring Guidelines and have familiarized themselves with its contents. Please email me with your goals, available times, type and amount of herbal education, etc. and we will see if we are a good match.
As to my educational and clinical background: After privately studying nutrition and wild foods in the early 1980s while working as a lab technician, I followed this up with intense private studies in herbal medicine in the mid-to-late 1980s and early 1990s. This was followed by four years of formal herbal education—first in Western herbalism, biology, physiology, and pathophysiology through Wild Rose College of Natural Healing (1997-1999), during which time I started seeing clients, and then with Traditional Chinese Medicine at the American Academy of Acupuncture and Oriental Medicine (2000-2001). In early 2000, I was asked by a physician friend of mine to join the first alternative-medicine clinic on a medical campus in my state of Minnesota, where I served as its clinical herbalist through 2002. I thereafter went into private practice, opening up my own integrative clinic, where I put together a team of 7 providers of different modalities. Over the past 20 years, I have worked with thousands of different clients, helping them to reclaim their health and vitality.
Mentoring specialties include: (1) Case Analysis/Case Reviews; (2) Functional Laboratory Analysis; (3) Protocol Design; (4) Herbal Formulation; (5) Integrating Western Herbs with Asian Herbs; (6) Nutrition; (7) Dispensary Set-up; and (8) Office Set-up and Management.
Potential mentoring methods include email, phone, or Skype. In closing, I very much look forward to working with you to help establish your clinical skills and confidence!

Chanchal Cabrera, MSc, FNIMH, RH(AHG)

I have been in general practice as a medical herbalist since 1987 with a specialty for the past 15 years in helping patients navigate cancer treatment. I trained in the 4 year program under Hein Zeylstra in England in the 1980's and moved to Canada in 1988. In the early 1990s I was academic dean for Dominion Herbal College in BC, where I designed, developed and delivered Canada's first classroom, clinical herbal medicine diploma program. I subsequently created a 3 year full time program in herbal medicine for Wild Rose College in Vancouver and helped develop the Herbal Science degree for Bastyr University. I also opened Gaia Garden Herbal Apothecary in 1993, a full service herbal medicine store and clinic, which I owned and ran for 11 years, expanding to 3 shops, almost 600 own-label products and 16 full time staff.

After 15 years in clinical practice, I went back to take my Master's degree in herbal medicine at the University of Wales. This program emphasized Holistic Science Methodology and we were required to apply academic rigor to holistic practice, validating the subjective as well as the objective, experiencing herbal medicine not just talking about it. As well as pursuing my thesis research into breast cancer and herbal medicine, I became interested in what other ways we can apply herbs to wellness and this led me to a certificate program in Horticulture Therapy which I completed in 2005. In 2016 I was lucky enough to go to Japan to take a certificate program in Shinrin Yoku (forest bathing therapy) and I bring much of this experiential practice to my herbal work now.

In 2013 I took the 10 week diploma in Botanic Garden Management at Royal Botanic Garden Kew in London, and in 2014 I took their 6 week diploma in Botanic Garden Education. I grow almost half the herbs I use for teas in the clinic. My gardens are a registered botanic garden and we open to the public and offer education and conservation.

I practice western holistic, bio-medical herbalism, integrating natural medicines and nutrition into conventional health care systems. I work with around 10 - 12 patients a week, some in person and some by telephone and email. I also teach herbal medicine and the concept of food as medicine. Once a month I run a free community clinic staffed by senior students under supervision.

I have an extensive dispensary of tinctures, creams, volatile oils and tea and a deep experience in product development, marketing, retailing, quality control and good manufacturing practices. I also have a background in education design and curriculum development and I am a registered schools auditor for the Private Career Training Institutions Agency that registers private colleges in BC.

My hourly rate for business coaching and for consulting with other practitioners on their cases, is $100. However, for AHG student members I am available at $50 for clinical or business coaching. Sorry, no trade options.


Greta de la Montagne, RH(AHG)

I've been practicing western clinical herbalism since 1992, when I graduated from the Southwest School of Botanical Medicine with Michael Moore.  During this time I helped start what is now the Center for Biological Diversity.  I soon began offering herbal first aid and consultations at Earth First! direct actions and supported several pivotal campaigns with healthcare advice and medicines.  I became interested in Ayurveda while based near Albuquerque because I was seeking more tools for assessment of the human body and its ailments and so began my studies at the Ayurvedic Institute under Dr. Vasant Lad, where I became certified as an Ayurvedic Lifestyle Counselor.  I focused on Pancha Karma and Ayurvedic Herbology. In 1994, after graduating from the Ayurvedic Institute, I founded the MASHH Clinic (Medicine for Activists Seeking Health and Healing) and traveled around the west with the apothecary in a converted schoolbus.  I deeply enjoyed supporting activists with herbs who were working for protection of threatened wild places.  I studied bodywork at the Heartwood Institute for over a year, which allowed me to connect back with my athletic background.  I graduated with over 1000 hours of training in Deep Tissue, Polarity, Swedish, Shiatsu, TMJ, and Sports massage techniques.  The year was 1996-97 and the struggle to save the ancient redwoods of Headwaters Forest from liquidation by MAXXAM was at its height.  Nearly every weekend I would leave school and travel down to where the nonviolent direct actions and blockades were taking place, to offer herbal first aid and support.  In late 1999, I helped administer the first aid clinic in the convergence space at the WTO protests in Seattle and this experience provided a huge leap forward in my herbal first aid skills and clinic administration.  I then certified in Wilderness First Response(WFR) and began to host bi-annual WFR trainings geared toward street and forest medics. I co-founded the nonprofit Cascadia Health Educators (CHE), worked with Black Cross Health Collective to find remedies for Chemical Weapons, and was the camp herbalist at Ruckus Society Action Camps for a few years. I live on a small microhomestead in the redwoods on the Lost Coast near Arcata, California where I am attempting to grow or trade for all the herbs I need for my apothecary.   AHG Professional member since 1999, I have a busy clinical practice,  two children -one deceased-, who I have raised using primarily herbs for medicine.   We care for dogs, cats, chickens and goats and feed them herbs too!  In the summer months, I staff and administer Herbal First Aid and Wellness Clinics at large outdoor gatherings, mainly herbal conferences, and endeavor to train more people in this area of expertise.  I am looking for some outstanding folks to mentor.  Work trades are possible, food and space for sleeping are possibilities for the right person(s)or couple. Distance and in person, Work Trade available (herb harvesting, washing or drying, processing and packaging, and manual labor with shovel, hoe & rake.  Hide tanners highly valued.  General farm labor includes digging, weeding and compost turning, livestock caretaking,  Apothecary support includes cleaning, bottle washing, and seasonal mundane tasks.  Clinic support includes regular inventory, moving large amounts of gear, occasional wildcrafting trips and full participation assistance at events. Candidate should have solid medicine-making skills, be handy with tools, able to tent camp, easy going, and good with animals.

Thomas Easley

Thomas Easley, RH(AHG), is the Director of the Eclectic School of Herbal Medicine and Founder of Functional Herbalism™, a system of medicine that blends Traditional Western Herbalism with Clinical Nutrition and Functional Medicine.

Thomas saw over 15,000 people in a full time clinical practice from 2001 until 2015, when he slowed his private practice down to launch the only full time clinical herbalism program in the country. Thomas rarely takes on students for mentoring who haven’t studied at his school. He strongly suggests that you find other mentors until you feel comfortable with clinical practice. If you are currently in practice, knowledgeable in Western Herbalism, and Clinical Nutrition, comfortable with modern medical testing, and would like to apply for a mentoring spot, email three case soap notes to mentoring at eclecticschoolofherbalmedicine.com for consideration. Mentoring cost is $75 an hour for advanced students, and $200 an hour for professionals. Mentoring can be done in person in Lowgap NC, or via phone/skype.

Susan J Fidler, MS, RH(AHG)

Susan Fidler trained at the College of Phytotherapy in the UK where she qualified with honors. The degree program included over 500 hours of rigorous clinical training with clients at the London Clinic of Phytotherapy and with other full-time herbalists. Good pharmacy practise was a necessary part of graduation, and the current clinic endeavors to comply strictly to good manufacturing practise. The office is in a medium sized town in TN to which a wide cross section of clients have access. Custom blends of herbs are made for each client and these may be supplemented with high quality products as needed. Over 30 herbs are wildcrafted and others are supplied from organic growers locally whenever possible. Susan is also trained in TBM and uses muscle testing as part of her analysis. From time to time biofeedback testing is also done using an Asyra machine. Every effort is made to ensure cooperation with any other health providers that a client may have wherever possible. This includes talking directly to members of the medical profession and checking blood work and other test results to assess progress. Great care is taken with possible herb-drug interaction, but also the nutritional deficiencies caused directly by drug therapy. Riverdell Herbs LLC has its own herbal dispensary with strict oversight and computerised batch management. Any student would be expected to become familiar with the Batch Master system, dispensing routines and necessary sanitation procedures. At present there are no opportunities for employment. Specialty areas you are available to offer mentees. (See details below.) Many people in East Tennessee are from Scots-Irish descent, and are thus statistically far more likely to be gluten intolerant than other people groups. Thus at Riverdell Herbs we have specialised in herbal management of subsequent disease/malnutrition states of these clients. Because of the Appalachians nearby there is a high incidence of tick-borne diseases and the clinic works with many people afflicted with Lyme disease. In person only, $7/hour. Trade considered depending on the student's abilities, weeding, garden work, making tinctures, wildcrafting etc. Differential diagnosis, Nutritional medicine, Red flags for urgent referral, Building an appropriate referral network, Legal issues pertinent to region/scope of practice, etc., Dispensing and formulating and medicine making; herbal pharmacy/cGMP issues, Herb/drug/nutrient interaction, Office management, elementary tongue and pulse diagnosis, plus "reading the signs" western style.
