APP Wellness Champion

My name is Sarah Jaber. I’m an Acute Care NP working mainly in the surgical/trauma ICU & also cover the CTI, 7800 SICU, and EICU. I have been working at Washu for over seven years now and love it, and recently graduated with my doctorate (DNP)! I have one cat and one dog, am currently rehabbing my house, love staying active, and love to travel!

My current goals as a wellness champion would consist of:

    1. bringing more attention to physical and mental health

    1. Identifying active issues related to our workspace, life, current events, etc.

I am always open for conversation with anyone who wants to talk or reach out!
