I would sure rather take note of chapter installations than de-installations, but here's another one of the latter.
Phi Rho at UOP, in Stockton, California (that's about 100 miles east of San Francisco, I think), was suspended with effect from April, 2019, owing to "declining numbers," for a minimum of four years.
The chapter was established in 1959.
Surely I don't know the reason for the recent mass death event of our California chapters (five suspended for low rush results in the past 9-10 years, IIRC)
, but I hope that the national has analyzed it all and has a plan for a bright future!
Meanwhile some of these suspended chapters still appear as active, on the wonderful list of every DDD chapter ever in this forum, and the list-keeper may wish to fix the list up with the additions and suspensions of the past few years across the nation.
