"Hubert Karreman, VMD has been involved with organic agriculture since 1988 when he was a herdsman at Seven Stars Farm in Kimberton, Pennsylvania. He saw homeopathic remedies work so well there that he decided to go to veterinary school to learn "the real thing" in order to mix and match modes of treatment as each case would require. He was a full-time dairy veterinarian from 1995-2010, working primarily with organic cows in the Lancaster area of Pennsylvania. He served five years on the National Organic Standards Board (2005-2010) and has been an invited speaker for farmer and veterinary groups across the U.S., Canada, and the European Union. He is now the veterinarian at the Rodale Institute".
