Power to Change’s speaker team is made up of Australians just like you. They are husbands, wives, mums and dads from all walks of life and varying work professions but united by a common passion; to encourage and equip you to build a strong, purpose-filled marriage; ultimately helping you find a ‘love that lasts’.


Each ‘A Day Together’ conference is typically presented by a combination of speaker couples with the husband and wife speaking together; an attractive dynamic to observe. Their presentations are biblically and professionally sound coupled with a great sense of humour. However, they are also imperfect just like you and they will illustrate their imperfections on the day. They look forward to meeting you soon……
