Trebor Lloyd Evans soon became well kown as a powerful and impressive preacher. He enjoyed working with children and young people in Dyffryn Nantlle, where he experienced Welsh culture at its best. He was equally hardworking with the young in Cwm Tawe. He established the Urdd Aelwyd youth club in Morriston and worked hard to establish the first Welsh primary school in Swansea, in Lonlas, Llansamlet. He was an enthusiastic Eisteddfod supporter and he competed as an elocutionist and adjudicated recitation competitions in the Urdd and National Eisteddfodau on numerous occasions.
He gained an University of Wales M.A. degree in 1949 for his work on Dr Lewis Edwards, Bala, which was published as Lewis Edwards, ei Fywyd a'i Waith, in 1967.

Trebor Lloyd Evans was an orderly man with a strong personality – a natural and able leader who was an interesting speaker and writer of substance. As Secretary of the Union of Independents he left his mark on their new publishing house, Tŷ John Penri, and ensured that it published a wide variety of books dealing with the Christian faith and its Nonconformist expression. He persuaded authors like Tecwyn Lloyd, R. E. Jones, R. Tudur Jones, Pennar Davies, Gwynfor Evans, Cassie Davies and others, to publish through Tŷ John Penri books which were greatly appreciated by Welsh readers.

“Dyn y Bregeth a'r Pethe
Yn gyson oedd, gwas y Ne”
