I have been performing weddings for 10 years. The majority of weddings that I perform are non-denominational secular (non-religious) weddings for 10 years now. The reason I chose to focus on non-denominational weddings is that I have met so many couples who don't come from different religious backgrounds or just don't feel religion has a lot to do with their decision to get married.
Reasons to Consider a Secular Non-Denominatioal Ceremony
You and your partner want to celebrate commitment and love more than a particular deity
You and your partner come from different religious backgrounds
You and your partner would are looking for alternatives to traditional wedding ceremonies
