HH Sri Chinna Jeeyar Swamiji- This is my Swamiji. He does a lot of good not only in India but around the world as well. He has set up many Chapters of his "Jeeyar Educational Trust" across the world and a they offer Prajna courses to help provide spiritual education. He comes to America quite regularly.
Sri Matham- A Math founded in Australia by Sri Rama Ramanuja Ācārya, himself an Aussie. Unfortunately he does not travel to the US as much as he used to. He is VERY knowledgeable and easy to speak to. Being western himself he knows how to convey complex thoughts in plain English. If you are in Australia, I highly recommend contacting him.
