Michael Alan Singer

Michael Alan "Mickey" Singer (or Michael A. Singer; born 6 May 1947) is an American author, journalist, motivational speaker, and former software developer. Singer is best known for his writings on spirituality, meditation, and New Age philosophy, and two of his books on the subject, The Untethered Soul (2007) and The Surrender Experiment (2015), were New York Times bestsellers. Singer established the Temple of the Universe, a yoga and meditation center in Alachua, Florida, in 1975.

Singer is also involved in the medical software industry. In 1981, he co-founded Medical Manager, now called Greenway Health, which marketed software that helped medical practitioners manage and digitize their billing records. In 2002, Medical Manager and its subsidiaries were bought by WebMD, in an acquisition valued at roughly $5 billion. Singer continued his work in physician software strategies at WebMD, before resigning in 2005. In 2010, Singer was prosecuted in relation to securities fraud during his time at WebMD, and eventually forfeited $2.5 million in settlements.
