Since I have been doing massage since 1987 when I graduated from Chicago School of Massage Therapy I have studied a few approaches in Health Care. Ortho-Bionomy (OB), Senior (Advance) Practitioner (in 1995) was my first approach that I studied. This system has taught me a greater sense of touch from basic Phase-4 to what I consider advance energy and cranial work. Cranial Sacral Therapy from different sources comes in second. NMT comes in a week third. These together has shown me diversity in my approach in a massage session. Glenn Heminover
