John Ferguson served over 20 years in the United States Marine Corp. During his military career he served two tours in Iraq and another in Afghanistan.

Upon his retirement, he and his family moved to Winchester where he began training as a surgical technician. Part of his training included a PE class where he discovered yoga. To help as many fellow veterans as possible he became a certified yoga instructor. He took Basic teachers training, Adaptive teacher training and Intermediate teacher training all at yogaville under Satya Greenstone. The yoga classes he teaches not only help strengthen the broken bodies of veterans, but also help fight the PTS and depression common among service members in a positive and drug free way. He uses Tibetan Singing bowls to help people who suffer from PTS quiet the mind and find a piece of peace.

In order to reach veterans outside the Winchester area, he authored, and with his wife Sheryl’s editing skills, published a book called Living Beyond PTS
