Lee Havis, Director International Montessori Society
Lee Havis began teaching in the Peace Corps in 1967, as an assistant professor in the Faculty of Engineering at the University of Panama. Returning to the United States, Lee began teaching young children in 1969, and continued in this classroom itedteaching in different situations for five years. In the 1970's, he completed graduate study in early childhood education at the University of Maryland and a JD in law at Catholic University of America (Washington, DC).
In 1976, Lee completed a Montessori diploma course with internship (primary level, 2-6) and conducted Montessori teacher education in the new organization National Center for Montessori Education he helped to establish. About this time, he initiated a tutoring program to provide one-to-one instruction to children in all subjects and ages in their home it is now operating as Trust Tutoring (
In 1979, he formed International Montessori Society (IMS), assuming the duties of its executive director and editor of its periodicals, Montessori Observer and Montessori News. Since 1986, he has conducted workshops and consultation to help improve Montessori teaching. In 2003, Lee discovered and consolidated a technology for the practice of true natural Montessori teaching which he discovered in 1979.
In 1994, he organized the basic operating documents for the new accrediting agency, International Montessori Accreditation Council (IMAC), becoming its director and now serving as well on its generic review committee. IMAC provides accreditation for Montessori teacher education, based on broad, inclusive standards to encourage the participation of all interested parties.
Lee has contributed to a number of Montessori texts, including introduction to Maria Montessori: Her Life and Work, by E.M.

In the 1960's, Lee Havis became active in the field of Montessori teaching, first as a teacher, and then later in the development of AMS teacher education. Due to conflicts with AMS, however, he led an effort to form a separate less "political" type of Montessori organization, which in 1976, came to be known as "National Center for Montessori Education" (NCME). By 1979, NCME was providing training through some 26 affiliated programs in the United States. The NCME training model was essentially the AMS "culture" philosophy type, however, similar in form and operation to the St. Nicholas Montessori College.
In 1979, Havis discovered a new understanding of Montessori teaching, which was a way of being committed to laws of nature, rather than the conventional commitment to either personality or culture. Since he found that this approach consistently brought about the child's true nature, he described this as "true natural" Montessori teaching to distinguish it from the "culture" and "personality" types.
Based on this distinctive Montessori philosophy, Havis established the "International Montessori Society" (IMS) to direct and guide activities and support its practice through training teachers, recognizing schools, and building up an international support network as described and presented at this website:
While both AMS and AMI sought exclusive domination in this accreditation field, Lee Havis led the effort for a third type of accrediting agency to serve as an inclusive "umbrella" structure for the entire Montessori community.

In 1969, Lee Havis began studying the problem of the original type of Montessori teaching, first as a classroom teacher, and then later by directing training programs for Montessori teaching in the 1970's.
Through this process, Lee solved this problem in 1979, by discovering how Montessori teaching works to bring about the child's true nature. Based on this discovery, he established the International Montessori Society (IMS) to share his experience and knowledge of this true natural Montessori teaching with others through such means as the IMS Montessori teacher education program.
In 2003, Lee consolidated a comprehensive technology for successfully practicing true natural Montessori teaching, consisting of 10 techniques, 20 protocols, 3 lesson presentations and various safe words.
