Name of book series with siblings who own an event planning business

[Faith]

The siblings run an event planning company.

I think their last name is Loveless

One of the sisters, the oldest, is named Olivia, and she is known for her highly organized nature, which includes using a shared family calendar to manage their personal and professional lives.

There is a gay brother, and a major plot point in one of the books involves his story, where he is married to a doctor.

[MJ]

No weddings. Can’t actually remember much about it, thought it is a siblings in event planning.
