  • Joel Silverman DVM
    Chairman of the Israel Equine Veterinary Association
    The Israel equine veterinary association invited Clair Thunes from Summit equine nutrition to our annual 2019 conference as an equine nutrition specialist. Her lectures included determining nutritional requirements and understanding how to build a balanced diet, feeding horses suffering from gastrointestinal metabolic and neuromuscular problems, and many more important nutritional issues. Her lectures gave us much needed practical tools and understanding in this challenging field.

    Clair's lectures where informative practical and interesting, given in a clear deductive and excellently presented manner including well-chosen case studies.

    We received only congratulatory remarks from our equine vets.

    Personally, I had the privilege of having Clair over with my family for Friday evening dinner and then spending a day wondering through the packed streets of the old city of Jerusalem, we had a great time and Clair is wonderful company.

    Dressage Education Chair, NCDCTA
    The North Carolina Dressage and Combined Training Association hosted a Zoom seminar with Dr. Clair Thunes on feeding to improve topline. Our membership was so impressed and appreciative of her knowledge and presentation skills! Her scientific explanations were geared at an appropriate level to keep our audience engaged, and she was attentive and thorough about answering our members’ questions. Our members have horses of a variety of ages and breeds, and everyone learned something that could help their horse. Dr. Thunes is an excellent resource for anyone looking to better understand and optimize their horse’s diet. Thanks from all of us at NCDCTA!
