North Star Integration

North Star Integration was founded in 2007 to help our clients integrate a better sense of wellness in all parts of their lives–body, mind, and spirit. We take a holistic approach on this journey to wellness, rather than a reductionist one. You are more than your symptoms. We are proud to call Portland, OR our home.

Rolfing® Structural Integration was the first service to be offered. Over the years, Neural Manipulation and Visceral Manipulation have also been added.

Jon says…

“I received my initial Ten Series in 2004. I had originally heard of Rolfing a few years before that, but I hadn’t seriously considered getting the work. The idea of it was always in my subconscious, though. Like most people, I woke up with the occasional sore back or neck, but it was nothing alarming or out of the ordinary. I also had the ‘standard’ pains from being a moderately active person (who didn’t stretch enough). Overall I didn’t have any major complaints with my body. However, I knew that I wasn’t using my body to its full potential. So, I decided to go for Rolfing.

Was I ever wrong!!! After the first session, I came to the realization that I had never taken a ‘full’ breath in my entire life. After the fascia around my lungs was opened up, I couldn’t believe the difference from just one session. I was definitely hooked. It was after this first session that I decided I would like to become a Rolfer and help other people experience a similar awakening of wonder at their own body and being. Over the course of the rest of my series, I continued to become aware of ways that my body had become limited over time. Most importantly, I learned new ways to use my body to help use it more efficiently and keep it operating at that level.

Before becoming a Rolfer, I was a computer engineer for a major telecommunications firm. However, I wanted to find a career that was more personally fulfilling, as well one that allowed me to help people. I strongly believe that the problem solving skills and methodical thinking learned as an engineer are invaluable towards being an effective Rolfer.”
