5:45 PM, Tuesday, October 20, 2015. “Little Father” Fr. Sergious Gerken travels the country visiting centenarians. And, while he once headed the Russian Orthadox church in Calistoga, he now lives and practices in Hernando, Florida. Father Gerken spent eight years at the Simonopetra Monastery at Mt. Athos, Greece where he learned to begin each day at 4 AM , a practice to which he still subscribes.
