As an organization, we are committed to the following Star Care Values:

Safety – Were my actions safe for me, for my colleagues, for other professionals and for the public?

Team-Based Approach – Were my actions taken with due regard for the opinions and feelings of my co-workers, even those from other agencies?

Attention to Human Needs – Did I treat my customer as a person? Was I kind? Did I use his or her name throughout the encounter? Did I listen to the customer’s concerns and was my response appropriate?

Respect – Did I act towards my customer, my colleagues, my first responders, the hospital staff, and the public with the kind of respect that I would have wanted to receive myself?

Customer Accountability – If I were face-to-face right now with the customers I dealt with, could I look them in the eye and say, “I did my very best for you!”.

Appropriateness – Was my service consistent with focusing on job 1; which is taking care of our internal and external customers – medically, professionally, legally, and practically, considering the circumstances I faced?

Reasonable Actions – Did my actions make sense? Would a reasonable colleague of my experience have acted similarly under the same circumstances?

Ethical Behavior – Were my actions fair and honest in every way? How would my family feel if this were on the front of the newspaper?
