David is doing cutting edge work in the field of bodywork, and it would take 3 or 4 teachers to replace what he knows.

With 18 years experience in the health care professions, I appreciate soundly researched and scientifically based approaches to rehabilitation. The DSL Method has expanded and refined my understanding and applications for achieving postural correctness and pain relief in less time. David has a unique way of reiterating known fundamental laws, redefining erroneous concepts, and instructing the participants through a successful treatment program.

The DSL Method has been an eye opening experience and has changed the direction of my work. David’s work is challenging because it is precise and logical, yet its openness inspires my own creativity. I have been motivated to study the physiological principles behind good bodywork in a new, more effective light.
