Michael has spoken numerous times at the New York Society for Ethical Culture. His talks explore a humanist stance towards life and are grounded in the philosophical and religious ideals of Ethical Culture. In private life Michael has his own architectural practice and projects include 262 affordable homes in the Bronx, a Community Center for St. Jerome's Church in the Bronx, and a lead free safe house in Brooklyn, New York. To move from the practical to the sublime, Michael has presented two Technical Papers on Space Station Design at industry conferences and space station designs he collaborated on with his mentor Michael Kalil are now part of the Museum of Modern Art's permanent collection.

Michael's other involvements include past membership on the Board of the Michael Kalil Foundation for Smart Design, established in 2001 in memory of designer Michael Kalil at the Department of Architecture, Parsons School of Design; past membership of the Steering and Executive Committees of the Live/Work Coalition of New York, a group he helped organize, which sought legislation extending coverage to new generations of Loft conversions; and past membership of Community Board 1 in Brooklyn where he served as Second Vice Chair (chair of the land use committee) for two years.
