Premier Service is one of my top premier MSCs. They are golden in my book. They have always respected me as a shopper even when I was a rookie, almost 10 years ago. They have given me their support many, many times during times when MSCs are expected to be always on the side of the client. I recommend them highly.
Their schedulers and editors are friendly and accommodating. They pay around the middle of the next month of the shop. There had never been any pay issue.
With them, your record and reputation is your badge. It is inspiring to work with people who value your service and make you aware of it.
