The organization for adults who live, or want to live, the Master/slave lifestyle.
MAsT was founded in 1988 in San Francisco by Fred Vaselenak and his slave michel as a support organization for gay men in Master/slave relationships. During this time Luke Owen was instrumental in developing the International Master/slave Contest as part of MAsT.
Following the death of slave michel ownership of MAsT passed to Bob Fifield and slave joe who continued to look for ways to help the members in their relationships. During this time the MAsT: Chicago Chapter was formed by Master Jack Rinella as the first MAsT Chapter separate from the original organization in San Francisco.
Then Master Roger Curtman and slave bill, International Master and slave 1997, took up the ownership of MAsT and made the concept of local Chapters a wider reality. On their watch MAsT was opened up as a pansexual organization. During this time the use of the internet became an effective tool for spreading information about MAsT. Master Roger engaged Master Alex Keppeler to take on the tasks of developing websites for MAsT: Atlanta and MAsT International. Master Alex went on to develop them for most of the rest of the MAsT Chapters. In 1999 under the leadership of Guy Baldwin the weekend conference dedicated to the Master/slave lifestyle was first developed. Also in this time period the International Master/slave Contest was separated from MAsT.
In November 2000 Master Alex Keppeler, slave john and slave kevin of Household Keppeler received ownership of MAsT with its seven functioning local Chapters. The Household immediately began work to provide a solid organizational foundation and structure to MAsT with the incorporation of MAsT as a Michigan non profit corporation and with the development of written policies and procedures for the MAsT National Office and local MAsT Chapters. They also developed and published guidelines for the formation of new Chapters. Following the death of slave john on April 2, 2001, Master Alex and slave kevin continued the process of developing and increasing local chapters and seeking to expand MAsT membership and recognition.
In 2004 Master Bert Cutler, the Chapter Director of the MAsT: Phoenix Chapter and International Master 2003, became the MAsT Liaison Officer to Chapters in Formation and a member of the MAsT Board of Directors. His task is to provide guidance and support to newly developing MAsT Chapters during their formation period.
In February 2007, MAsT International underwent major changes. MAsT joined Butchmann's Inc, family as a 501 (c) (3) not for profit educational and support resource. Master Bert was appointed as Butchmann's Liaison Board member. Master Konrahd was appointed as Executive Director of MAsT International, slave cat was appointed Directors of Operations and MsSuzan was appointed Deputy Director of MAsT International. In June 2007, MsSuzan moved to Director of Operations MAsT International and the position of Deputy Director was abolished.
In May 2008 the position of Deputy Director was re-established and the position was filled by Master Bob Blount. The position of Junior Regional Representative was created along with a specific job description and duties.
In June 2009 the position of Financial Officer was created and the position filled by slave bonnie. In October 2009 Master Konrahd stepped down as Executive Director and was replaced by Master Bob Blount.
As Mast continued to grow, additional positions were added to the Executive Committee in 2010 in order to provide the support needed by individual chapters. The Membership Director was filled by slave patrick.
