All OSI's are held at Saddleback Laguna Masonic Center, located at 23685 Birtcher Drive in Lake Forest. We will start all of our sessions in the dining room promptly at 6:30pm, and will always conclude by 9:00pm. The "Host Lodge" is the lodge responsible for providing refreshments, leading the opening prayer, and their officers will begin any exemplification we have scheduled for that school. Officers are required to attend OSI - but you are welcome to invite any potential officers you feel would benefit from the experience to an OSI meeting.
