As Chair of 7 South Street Treatment Centre, I had the pleasure of working with Catherine McCullough of CMC Leadership as she guided both our strategic planning process and a DISC-based professional development session for our staff and board. Catherine brought clarity, structure, and insight that strengthened alignment across our organization while fostering meaningful leadership growth. Her professionalism and ability to engage diverse stakeholders made a lasting positive impact on our team.

Lambton Kent District School Board
I engaged Catherine to assist Trustees and Senior Administration with the process. She supported significant pre-meeting preparations, reviewed our existing materials and engaged in conversation to understand our local context. After only one day, Catherine facilitated a session to move us from a dated strategic plan to a current and relevant set of strategic priorities. Catherine continued to support our work with implementation and considerations...

I had the opportunity to learn from Catherine over an 8 month period. Her approach to leadership was fresh and new and she had a special ability to tie lessons directly to day to day issues that I was facing during my job. Outside of the class, she was insightful and genuinely interest in helping others succeed. I can say nothing but positive things about Catherine, and would highly recommend her to anyone looking to bolster their leadership or that of their team!
