榮天愛樂合唱團，是由青年指揮家張天慧成立於2017年10月的一支年輕合唱團。鋼琴伴奏為黃以睿和張蕾妮（見習伴奏）。每一位團員都是經過指揮嚴格面試挑選的、具有較高音樂修養的愛樂人士。團員們發自內心地熱愛音樂，熱愛生活，並且有信仰、有追求，希望在張指揮專業的指導下，用美好的音樂榮耀天主、傳遞愛心、感動聽眾。
榮天愛樂合唱團成立不到兩年，就被甄選參加了2018年迪斯尼聖誕燭光音樂會。2019年5月與Anaheim 第一長老會教會唱詩班一起演出了神劇《彌賽亞》。合唱團還不定時地舉辦小型演出活動，用美好的歌聲為教會、社區、養老院送上愛心和關懷。
Gloria Master Chorale (GMC) was established by director Tian Hui Zhang in October of 2017, with accompanist Eric Huang and student accompanist Leilani Zhang. As one of the only audition choruses in Orange County, GMC' s choristers share a love and appreciation for choral music, and are united in their desire of using music to serve the Lord. We hope to grow in the upcoming years and continue inspiring joy in our audience.
In just two years, GMC has been invited to perform in the 2018 Candlelight Procession at Disneyland, as well as selections from the Handel Messiah alongside Anaheim First Presbyterian Church. We have also been blessed to bring our music to various churches, communities, and senior homes in our area.
