Its enrollment is currently around 1100 after losing about 600 students to St. Francis Xavier Catholic High School in 2009 & 2010, after the completion of its construction in 2009.

St. Francis Xavier is located just down Limebank Road, less than 10 minutes from St. Mark.

[1] There are a few original faculty members who still teach at St. Mark along with many others who have long been a part of the staff.

In 2005, St. Mark celebrated its 25th anniversary and past faculty and alumni were invited to attend reunion festivities.

The school has gained increasing media publicity because of the food drive.
