Thursday, August 16, 2018

I sent my child to Monarch for a couple of years before moving them out of there. The teachers spend a large portion of their time complaining about the current political state of affairs than they do teaching the students. Showing videos from cable late night shows where the host is dropping F bombs left and right is not something I imagined they would be doing at any school but apparently, it is ok at Monarch. My student would have a difficult time avoiding the issues that plague this school. Drugs, vaping and alcohol have been staples that this school has been known for. The police routinely respond to this school on these issues as well as teachers being involved in inappropriate situations with students. I know the former SRO at this school and the stories from her are appalling. This is a very affluent (or so they think) community where money and social status takes precedent over the students academics. We have friends that currently work for the Boulder Valley School District. They had also moved their kids out of Monarch over a decade ago for the same issues and problems. Those kids have excelled and have gone on to wonderful careers with beautiful families. It is unfortunate, but we are glad to have left that school for a better environment for our child.
