Martine Jourde


Martine is a professional homeopath and founder of the NPO organization HTSF in 2006. Her background of an integrated homeopathic approach to physiology, epidemiology, and community health, as well as her more than 45 years of professional experience, both in private practice as well as in community settings in Canada, France and Cuba among other countries, make her an expert in the use of homeopathy to strengthen communities.

Because of its ecological and economic aspects, homeopathy can contribute to sustainable development and to access to proactive health, wellbeing, self and comfort care and prevention in both the developing and Western worlds. Martine’s strong motivation comes from all these years of seeing the positive impact of homeopathy wherever it is used and knowing that homeopathy can help to restore harmony between all living organisms on the planet.

Carla Marcelis


Homeopathy grabbed Carla’s attention from the moment she first learned about it while in medical school, many years ago. She decided that homeopathy and naturopathy were her preferred ways of working with health, as it allows for deeply knowing the people you work with and their families and communities. She was very excited to be invited to join HTSF missions to Honduras and became the mission leader and coordinator of the HTSF work in Honduras for a number of years. Apart from having a thriving practice, Carla is also a teacher and Director of the Montreal Institute of Classical Homeopathy (MICH).

Carla has put her full support and passion behind the Honduras project. Bringing homeopathy to the world is one of her dreams. The knowledge that homeopathy can do so much for people’s health while costing so little, makes it an important medicine for developing countries such as Honduras.
