Mark Certo is a former recording engineer at the Monroe Institute. Working with Robert Monroe during the last 7 years of his life, Mark was given the great gift of friendship and personal interaction with Bob. After Bob's passing, Mark stayed on at the Monroe Institute for another six years helping to create many of the programs at Monroe today.

It was at the age of 17 that Mark was first inspired to explore expanded states of consciousness, realizing it was key to living a successful life. He began studying and practicing meditation to improve his ability to use consciousness toward achieving his goals. His practice led him to understand certain aspects of himself on a multidimensional level.

In 2001, Mark said goodbye to his life in Virginia to explore and study consciousness outside of Bob’s model and influence. Inspired by his studies of comparative religion and Jungian psychology, Mark synthesized a new method of consciousness exploration called the Triad Mind.
