Liandro was born Feb. 7, 1949, in Fond du Lac, the son of Rev. Pedro and Emelia (Lugo) Arellano. He graduated from Fond du Lac High School in 1967, where he lettered in wrestling. He attended Seattle Bible College and the University of Wisconsin-Oshkosh.
He served as youth pastor and associate pastor at Gospel Tabernacle (Lighthouse Church) in Fond du Lac. He was a member of the Fond du Lac Sea Scouts and the Fond du Lac Clergy Association. He married Margaret “Peggy” Mand on Jan. 19, 1980, in Fond du Lac.
He was a longtime member of the Fellowship of Christian Assemblies, where he served as a regional elder. He was pastor of Faith Assembly Church and superintendent of Faith Christian School in Grand Detour, Illinois, for 28 years. He also served on the Dixon YMCA Board and the Hope Life Center Board.
Pastor Li loved playing his accordion and enjoyed traveling, taking many trips with his wife and family, as well as numerous mission trips with youth. He understood youth culture and served as a youth pastor for many years. He took preaching the Word of God seriously and loved reading and conducting research.
After retirement, he could often be found tending his vegetable garden or working on his woodpile and splitting wood. He had a refined interest in food and enjoyed developing his culinary skills, which resulted in feeding everyone who came to his home.
