Blessed Mary Angela, foundress of the Felician Sisters, dedicated her life to serving others. All OLSH students are encouraged to serve where they are needed, living out the Felician Core Values.

Every month, 10-20 students are able to leave school to do service work with a faculty or staff member on a Core Values Service Day. In addition, the entire senior class participates in a Senior Day of Service, where they volunteer at a charity of their choice for an entire day. Furthermore, OLSH faculty, staff, and students regularly participate in service during the weekends as opportunities arrive. Every year for the past 5 years, students have collectively performed over 10,000 hours of service a year or more!

In May, during the Honors Convocation ceremony, yearly service recognition awards are presented. These awards include:

• 75-100.99 service hours - Bronze Award
• 101- 150.99 service hours - Silver Award
• 151-250.99 service hours - Gold Award
• 251 or more service hours - Platinum Award
