Experience about denominations?

Hi,

I am a person that attends a local church and I was wondering, do any of you have experience of going to several different demoninations and then ending up in the local church, and if so, do you think it is profitable to remain in demoninations at all? The scripture states that we should "greet every saint" in Christ Jesus, yet I am unsure as to whether we should distance ourselves from denominational Christians. What are your opinions about denominations, whether good or bad?

Thanks,

David
