I would recommend you work at a level 3 as the bulk of higher acuity patients are seen there and usually in an environment where increased hands-on care and slightly slower paced mentoring will occur.
Be careful for what you want, you may get it.
I encourage people to develop teamwork, then skills and communication. Once you feel comfortable in your own shoes then increase your skills through education and that would possible include certification and possible movement to a higher level of patient acuity in a Level 1 or 2 Trauma Center.
Remember.....this is a marathon, not a sprint.
