Robert A. Koch is a professional Vedic astrologer with more than 16 years experience, and has earned an international reputation as a lecturer, author, and teacher of Jyotish (Vedic Astrology). In his work, he draws upon the experience gained from serving 20 years as a Hindu-Vaishnava monk in the USA, Canada and India. His spiritual teacher and guru, the late Sri Srimad A.C. Bhaktivedanta Swami Prabhupada, is revered as one of the most prolific teachers of Vedic thought in the modern age.

In the late 1970's Robert traveled to India numerous times, where he learned Vedic scriptures and astrology, gaining first-hand experience of the culture founded upon their principles. In 1987 he left the monastic life and returned to America, where he began his full-time professional practice of Vedic astrology. Robert wanted to bridge the gap between the ancient Sanskrit Vedas and Vedic culture, and the scientific intellectual culture of the west. His mission therefore developed into a significant vehicle through which the Vedic teachings could be more easily understood and implemented by the western mind.

In 1999 Robert met his Jyotish guru, Pandita Sanjay Rath, who is the current representative of the Sri Achyuta Jyotish Parampara and who founded the Sri Jagannatha Center (SJC) for the teaching and promotion of Vedic Astrology worldwide. Soon thereafter, Robert was promoted to the faculty of SJC and awarded the position of Jyotish Guru for North and South America. Since that time, his lectures, research and writings on Vedic astrology have earned him appreciation and reputation among Jyotish colleagues and students alike. Robert also received a formal letter and Certificate of Commendation from the Bharatiya Vidya Bhavan, Indian Council of Astrological Sciences in 1999, for distinguished service in promoting Hindu-Vedic astrology in western countries.

Robert is the author of The Spiritual Dimensions of Vedic Astrology, which was released in early October, 2005. This book involves intensive research into the spiritual components of the Vedic horoscope, with specific reference to the esoteric timing method called "Drig Dasa."

Currently Robert resides in Bend, Oregon, USA, where he actively teaches and maintains an international clientele from all age groups and walks of life.
