Annunciation Cathedral hosts a variety of ministries. These include the Ladies Philoptochos Society; the Cathedral Choir; GOYA (Greek Orthodox Youth of America); FAITH, HOPE and JOY groups (for young children); PAREA (young adults); AGOSS (singles group). A chapter of Sea-Scouts of the Boy Scouts of America is sponsored by the cathedral. Other ministries, which meet on a regular basis, include marriage preparation and a grief-support group. Through its Philoptochos Society and other organizations, the Cathedral contributes to charitable organizations in the Houston area and nationwide. These charities include both religious and non-religious agencies which help the poor, the sick and those who are in distress. In addition, volunteers from the cathedral assist by translating for Greek-speaking international patients in the Texas Medical Center, visiting with patients and preparing food for those who can't do that for themselves.
