Trinity O' Club Welcomes You

We are part of the Fellowship of Orthodox Christians in America, an official organization of the Orthodox Church in America, and our mission is to proclaim, share and reveal our Orthodox Christian Faith through service, fellowship and example.

We strive to accomplish this by:

  • studying the tenets of our Faith support and encourage Orthodox Youth ministries
  • support and encourage missionary growth of our church
  • encourage and promote unity among all Orthodox jurisdictions
  • establish practical means for Orthodox Christians to endure lasting friendships on local and national levels through networking
  • provide educational, cultural, social and athletic activities for the people of our Orthodox Faith
Get Involved

The Trinity "O" Club was originally formed in 1946 when a group of young adults attended a dinner at the Cathedral in honor of servicemen returning from World War II and saw a need for a social club to attract young adults to return to the Cathedral. 

As a club belonging to the Midwest District of the Fellowship of Orthodox Christians in America, the Trinity "O" Club sponsors functions to support the Cathedral and various non-profit organizations.  We are currently seeking new members to join our fellowship. 

If you are interested in joining in the fun, contact Trinity "O" Club President, Sue Miller, at 847-204-1736 or isaa24@aol.com.

2016 Blini Luncheon

O Club's 2016 Blini Luncheon - 03/13/16

The Trinity "O" Club wishes to extend its heartfelt thanks to all the parishioners who made blini, to the children who dressed in traditional Russian costume and helped serve the food, and to everyone who supported the luncheon with their meal purchase.  We were so happy that Bishop PAUL was present to enjoy the day with us.

All proceeds from the event will be divided between Holy Trinity's Building and Restoration Fund and the 2016 FOCA Gifts of Love Project. This year, the Gifts of Love Project will help fund the creation of Orthodox coloring books in the Yupik language for the Yupik people of Alaska.
