The PTO board has proposed changes to our bylaws that reflect the reorganization work we did over the summer. Theses changes are highlighted in green/red on the draft below.
The main changes are:
  • Adding “annual fund” language to the section on dues.
  • Adding a 4th president to the co-president section.
  • Adding 2 more positions to the vice president section – and language to reflect that this role is being taken by our new pillar director positions and provides detail on the 6 director roles.

We tried to minimize changes while accurately reflecting what we are trying to do. Please see the revised bylaws: MR_Elementary_PTO_Bylaws_RevisedDraft1_13-Sept-2020

We will be voting on these changes at the September board meeting, scheduled for September 25th, at 8:30am. See PTO calendar for details.


Dear M-R families,
The PTO is relying on parents to update their family’s class and cohort assignments. By updating your contact information AND completing your student(s)’s class and cohort assignments in our database, the PTO will be able to direct communications in a way that reaches all families with information relevant to your children and help keep us all together this year, no matter the learning model. So, as soon as possible, please log onto Membership Toolkit and double check that your contact information is correct. Then be sure to click to the Step 2- Student Information to select Teacher and Attendance Model. Don’t forget to click the SAVE button before leaving the page!
