About
The Wagner Society of
Southern California…
…was founded in 1982 in Los
Angeles, California by
ophthalmologist
Sherwin Sloan,
M.D. When Dr.
Sloan, as a
fledgling "Ring"
fanatic, he listened to it so much that his
teenage children gave him an ultimatum,
he told The Times in 2003: They said, "It's either 'The Ring'
or us, and I said I'll help you pack.' Next day, they bought me
earphones." By the time of his passing Dr. Sloan saw over 90
performances of the Ring.
From the WSSC’s inception, It’s been an active avenue of
pursuit for those interested in Richard Wagner as an artist.
Since then meetings and programs have been held
approximately every other month with the finest of
speakers, performances and rare media regarding Wagner’s
life, music-dramas and influence.
From its inception the WSSC has had tributes honoring
Wagnerian artists. Past tributes have been awarded to Hans
Hotter, Jess Thomas, James King, Lyonie Rysanek, Helga
Dernesch, Siegfried Jerusalem, Jane Eaglen, Linda Watson,
Peter Seiffert and Petra-Maria Schnitzer, James Conlon,
Antoine Wagner, Mirella Hagan with each honoree present.
For over three decades the highlight of each summer is
when members of the society journey to the Bayreuth
Festival in Germany, lead by the society’s president. Dr.
Sloan passed away on May 31, 2010 during LA’s first Ring
cycle. (Sherwin, we miss you till this day!)
Celebrating 41 years as a society!

The Current Chairmen…
The year prior to Dr. Sloan’s passing he appointed John
Mastrogiovanni, D.Min. to be his successor. Dr. John was a
member of the WSSC since 1990 and assisted the society in
many areas. Since May 2010, Dr. John has taken the helm
and continued the legacy afforded to him locally, and in
particular taking members to the Bayreuth Festival yearly.
One of the key mandates that Dr. Sloan gave him was to
“continue the Gala Dinners at the Festival” which features
many of the performers of the Festival and members of the
Wagner societies from around the world.
As a young boy Dr. John, living in New York, was first
exposed to Wagner by his father at the ripe old age of five.
From that moment he began a passionate love for Wagner’s
works. At nine he began marking the piano scores of the
operas, outlining the leitmotifs. By the age of fifteen he
experienced his first Ring at the MET with Jess Thomas as
Siegfried and Birgit Nilsson as Brünnhilde. Being strongly
influenced by Wagner’s music, at twelve he picked up the
French Horn (he just had to play Siegfried’s horn call) and
played for six years. Nevertheless, he perfected the craft
enough that prior to finishing high school he participated in
a special gathering at the University of Hartfort and had the
privilege of playing with several hornists, including the
legendary Barry Tuckwell. With the influence of Wagner’s
message of redemption of the human condition, he became
an ordained minister in 1983 and in 1985 founded Oasis of
the Valley in Monrovia, California. He has also written and
published six books including one on Wagner’s final musical
treatise called, “Parsifal: The Will and Redemption.” Dr. John
enthusiastically serves as the Chairman and loves gathering
its members in the Los Angeles and San Diego area, as well
as his home.
