As we gather this June, we aren’t just attending a professional meeting, we are stepping into a historical slipstream 150 years in the making. This is the moment we have been building toward: the sesquicentennial celebration of our collective impact. This milestone is about more than looking back; it is about the momentum we carry into the next era.”
