The parish grew and prospered. In 1975, to meet the needs of the pastor’s growing family, the congregation built a new rectory. Over time Holy Trinity’s unique and beautiful edifice was filled with all necessary ecclesiastical appointments, and the parish took its place among the older established parishes of the Diocese. As further evidence of that achievement, an offshoot parish of Holy Trinity, Holy Spirit Mission in Sussex County, began holding services in 1988. Outreach activities have included regularly providing food for the needy, “adopting” a sister parish in Novosibirsk, Russia, and numerous other regular and ad hoc charitable ventures.
Church facility renovations and upgrades took place in 1991, 1997, and 2001. Beautiful sacred murals in the altar and choir were installed in 2003 and 2005. In 2003 Metropolitan HERMAN bestowed the Order of St. Innocent on Archpriest George Hasenecz, on the 40th anniversary of his priesthood. The parish celebrated its 40th anniversary in 2004, and in 2005 Fr. George marked the 40th year of his pastorate. In 2008 he announced his retirement. He was honored by the parish for his outstanding service to the Church, and Fr. David Fox began a transition period under Fr. George’s mentorship. The parish celebrated its 45th anniversary in 2009. In June 2011 Fr. David became Rector of Holy Trinity parish.
