Professional Background

Her background in construction litigation, combined with good preparation, enables her to identify the issues incisively. This enables her to reality-test the parties’ cases and assist them in evaluating their strengths and weaknesses. Rosemary’s approach is adaptable, and as well as facilitation she is able to deploy a blend of facilitation and evaluation to suit the particular mediation. Where invited (and if appropriate) she is willing to assist the parties by making evaluations, recommendations or post-mediation assessments.
