A letter From Our Executive Director
100 Years of ISSA and Still Moving Forward
by John Barrett
Wow! 100 years of ISSA. It’s hard to believe and yet incredibly gratifying that our association has thrived for a century. Truly, it’s a big deal and wouldn’t be possible without your continued commitment to our collective mission to change the way the world views cleaning.
Personally, I have worked in the cleaning industry for more than 30 years, and it’s been amazing to see how far we’ve come. ISSA has been a resilient and evolving force in the cleaning industry since its inception in 1923. The association has grown from six founding members to more than 10,500 members in 110 countries today. And we keep moving forward.
