CMMS PTSA Annual Fundraiser "Pass the Hat"

The CMMS PTSA Annual Fundraiser "Pass the Hat" is happening now. Our goal this year is to raise $18,000.
By donating funds to the CMMS PTSA, you help support and make positive changes to our school community. Your generous donations will directly support CMMS classroom supplies/equipment, grade level enrichment grants, student social events, PTSA programs (Angel, Gift-a-Book, Reflections, Staff Appreciation) and much more.

Double your donations! Many employers match donations and pay for the hours that you volunteer.  Every dollar counts! For more information, please click here or contact us.

We are grateful for the support and donations from our CMMS community!

Thank you CMMS PTSA!
