Mike is intense and his past success and business experience lend confidence and excitement to his sessions.  As opposed to other companies that merely come in and present training classes, SISU ensures clients are addressing actual business needs, refines learning needs down to their simplest form and identifies critical indicators of success.  Each participant is held accountable to learn and apply the information taught and Mike gives individual attention to each person to identify their strengths, overcome personal obstacles and taste success.  Once the word gets out that Mike is leading a session, people are clamoring to get into the class.
