Meet the Team
Benjamin Castells - Tenor, Abegail Castells - Soprano
Kevin Chang - Bass, Jessica Chang - Alto
Kevin (a Digital Marketer) and Jessica (an Elementary school teacher of 14 years) have been married for 12 years and are blessed with two daughters, Brielle and Kaylie. Music has always been woven into their lives—Jessica began singing with her sister at just four years old and also plays piano and violin, while Kevin participated in musicals through school and plays the trumpet, among other instruments.
As a married couple, they first sang in a family quartet with Jessica’s sister, Abby, and brother-in-law, Ben, and have continued to share music for over fifteen years. What started as a small family group has grown into a ministry that now includes their siblings, with music filling their home daily. Kevin and Jessica also serve their local church on the praise and worship team, cherishing every opportunity to lead others in worship.
“Our greatest joy is seeing hearts lifted to God through song.”
Jonathan Castells - Tenor, Sineyra Castells - Soprano
Jonathan and Sineyra have been happily married for eleven years and are parents to four children—Josiah, Eliza, Isabella, and Aliviah. Since childhood, they began singing and worshiping God, passing that love for worship to their children through family worship, car sing-alongs, and encouraging praise. Music and worship are central to their family life.
For Jonathan, music is a way to praise God, and Sineyra sees it as a means to serve by using her talents. Within Harmony of Truth, Jonathan is a tenor and flutist. Sineyra sings soprano and plays the violin.
They also serve in their church through music, worship, and children’s stories, living lives of service. Outside of music, Jonathan cares for animals on the farm and works as a nurse, reflecting his passion for God’s creation and healing. Sineyra shares her testimony and nurtures her family.
They enjoy farm life with goats, chickens, turkeys, a cat, and a dog, and have traveled through 24 states, living in four of them.
Their motto: “We ask and depend on the Holy Spirit to lead us,” and their prayer: “God is real, and He loves us.”
Kenneth Chang - Baritone, Sujai Chang - Alto
Kenneth and Sujai have been married for eight years and are blessed with two children—Jozilynn and Jaimisen—and remember a precious child who is resting in Christ. Their faith has always been central, but in 2020, they truly felt God’s comfort and love during difficult times, deepening their desire to share His peace and hope. Their faith underpins their family life and music ministry.
Music has played a major role in their lives, helping them connect with God and express gratitude for His talents. Ken began singing in his church choir, while Sujai started singing at age three with her sister Sineyra, later joining various choirs, musical groups, and her school orchestra through high school. These experiences fostered their love for worship and now inspire how they share music and in ministry. At Harmony of Truth, Ken sings baritone, and Sujai sings alto and plays the violin.
Outside of music, Sujai fulfills her calling as a licensed mental health therapist, serving others with compassion and modeling Christ’s love. Ken enjoys traveling and seeking new adventures, viewing each trip as a chance to admire God’s creation and to strengthen their family's faith. They also cherish simple joys like puzzles, board games, and road trips.
Their motto is: “Through every trial, our voices testify of God’s goodness.” They pray to inspire others with the truth that God is always present, comforting, and faithful—His ways are higher than ours.
