The headquarters for MSIA are located in the Historic West Adams district of Los Angeles.
In the early 1970’s, John-Roger went in search of a beautiful property that could serve as a home base for staff, initiates, and ministers to study and share the work of Soul Transcendence. He discovered a diamond in the rough that today has been transformed into a magnificent spiritual oasis in the city.
The main building on the property is an exquisite mansion, built by Italian winemaker Secundo Guasti around 1910. MSIA has rehabilitated the Italian Renaissance mansion, known in its day as the Guasti Villa, to its original splendor–carefully restoring ornate details, murals, and woodwork.
