MarkTwo Consulting employs highly capable and experienced consultants. Our consultants are professional facilitators for leadership development interactions and expert leadership assessors.

Many are accredited in the 3-dimensional organisational personality preference instrument for maximising performance called the Universal Hierarchy of Motivation. Several are also accredited in the personality inference instrument - the Pario Professional thematic questionnaire - which is ideal for selecting the best people into organizations or for identifying who is best for promotion. In addition many of these consultants are internationally accredited in behavioural interviewing (BEIs), executive coaching and/or life coaching.
