7 South Street Treatment Center

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.
