They know what you want
More than anyone else I've encountered, Mark is an expert in a variety of therapeutic modalities, and he never stops studying new ones. However, what matters most is his capacity for being there with the client, for being able to sense and anticipate what the client wants, and for providing that. Sometimes he completes in a single session what could have taken another therapist months to complete. He may be either a soft breeze or a bulldozer, depending on what you require.
