He is considered a renowned Diasporan author in the Western Armenian tradition with his own style of writing.

In 1933 he published his second book, also written in Armenian, The Betrayal of the Gods, a collection of short stories.

In 1937, he fell victim to the bone disease osteolysis, which disabled him and caused him much pain and suffering for the rest of his life, mostly spent in hospitals after he lost his home in 1939.
