Welcome, Izabella (what a lovely name.....)

Well, you haven't been there very long in the grand scheme of things, so I think there's hope.

Much as I hate it, sometimes you just have to kind of "put yourself out there" to get people's attention.  Now, I don't mean standing on your desk and singing :-), but try this:  when you walk into the office in the morning, smile, make eye contact, and say "Good Morning" to EVERYBODY you run into.  

It's a simple phrase, can't be misinterpreted much so there's little risk of foot-in-mouth disease, and you come across as approachable, friendly, pleasant, well-balanced.....you get the idea.  

Also, sometimes putting a voice with a name is as important as a face.  

I've found this to be useful in even the most clique-ish environments.  Face it, it's really hard to ignore someone's "good morning" in an office setting without looking like a completely rude jackass.  

Good luck and welcome!
