Counseling Materials

John B. Riebli Counselor

School counseling is considered a regular educational service and therefore students can be seen without parent consent. However, as a good faith practice, at the Mark West Union School District, the counselors will only meet with students one time without parent permission, usually to determine if counseling support is needed.

Our school counselors are happy to provide information about community resources if parents feel their student is in need of additional support but would prefer to receive it in the community.

Dress for Success

Students are expected to dress in a manner appropriate to an educational environment. Their appearance should be neat and acceptable to general society and in keeping with school activities.

Great safe environment for children to learn and have open space to enjoy physical exercise too.

My son started in 1st grade after a not so supportive kindergarten experience and I’ve watched him thrive and grow with all 3 years thus far at Riebli with great teachers!
