Heart swellinly ethical

Many years w/ Triodos Bank. Never anything but 100% help/guidance. Always amazed how encouraging and exciting their newsletter is given the negativity of the news and the opposite in values that seems rampant to Triodos. values and practices. They practice what they preach. Long may Triodos thrive and spread and prosper. Carol Reviewed on: 18th January 2022
