In 1975 Chaty Secaira had a vision in which she was asked to start doing spiritual work and to teach to others. From 1977 and onward she visited esoteric schools to gain experience in this field. In 1984 she started working with medicinal plants in San Antonio (Guatemala) to help the local population with their health issues. In 1988 she moved to Antigua to start a yoga school and a shop for natural health products, which she moved to Panajachel a year later. On July 11th, 1991 Las Pirámides was started in San Marcos La Laguna, during a total solar eclipse. Deep gratitude goes to the many people that have contributed to the growth of the Centre, including those who helped to build the various structures and those who provided support in other ways. Besides teaching, Chaty enjoys working on various projects for the benefit of San Marcos and it's surrounding villages, including running the radio-station (Radio Cosmos) and leading the non-profit, non-governmental organization Sembrando Esperanza to support the local community.

Marcus also teaches Hatha-Yoga in the mornings, and also guides some of the meditation classes in the afternoon. Marcus' hobby is the medicinal garden, and his expertise on medicinal plants enables him to regularly organize courses to educate guests who want to know more about the fascinating world of plants. You can also consult Marcus if you are interested in doing a Tarot-reading. He lives together with Melanie (see below) and their son Noah. Being an Englishman by birth, he has been working in the Centre for 14 years.

Melanie is involved in teaching parts of the Sun-course and guiding the self-expression sessions in the Moon-course. Melanie practices the Shalua-Ka healing therapy, and also regularly organizes courses to teach the therapy to others. She lives together with Marcus and their son Noah. French-Canadian Melanie has been working in Las Pirámides for 4 years.

The reception of Las Pirámides is manned by Josh and Joel. Gardeners Pedro, Carlos and Christobal take care of the medicinal garden and the grounds. Maria and Candelaria do the cleaning.
