Pros
The Santa Monica office is much smaller, so there is more opportunity to be noticed by upper management. The majority of the people here are very easy to get along with and fun to be around. Many people are able to leave the office most days around 6 or 6:30, some groups even earlier. Working on the weekends is also almost non-existent. The entire atmosphere is very relaxed, as are the clients - which can be good and bad. Good because you can come in a bit late or get out early once in a while if you need to, bad because it can make you develop bad habits or become unmotivated.
Cons
The Santa Monica office is looked at as the red-headed step child by the head New York office. The atmosphere is very quiet and not as family oriented as it used to be. Everyone comes in and does their job for the day and then leaves as soon as they can. There is not much comradary within the different departments and people only speak to each other about the business when they absolutely have to. The overall atmosphere is fairly negative, and compared to a lot of other agencies, most people that work here are not as motivated and excited as they should be about what they aer working on.
