There are a great number and variety of activities and clubs for both the middle and high school student at MHS. The school offers over 30 different clubs that range from the serious and dedicated (Medicine for Humanity, Amnesty International) to the fun and  creative (Positive Poets). These clubs are an important reminder that teen life goes beyond academics, arts and sports and that all students are welcome to be a part of something at MHS. More than 20 different faculty serve as club advisors.

The Operation Smile Club at MHS is one of the largest and most active chapters in the country. Each year, a select group of teachers and students go on Operation Smile missions to third world countries and then share their experiences with the entire school.
