Heidi Chang

Residency Program Administrator

Originally from Fresno, CA, I moved to the Bay Area after attending the University of San Francisco. I have a background in Graduate Medical Education, with a Masters in Healthcare Administration and am ecstatic to have joined the Internal Medicine Residency Team. I am here to offer administrative and educational support in a variety of areas during your training here. 

My work here is proudly supported by my partner and my two rescue pups, Luna and Harper.

I was born and raised in Oakland, CA, and I'm excited and proud to be working in the Internal Medicine Residency Program here at Highland Hospital. I'm inspired everyday by our program that houses a team of strong, caring and incredible physicians, faculty and residents that believe in making a difference. 


Disney holds a special place in my heart. If I'm not soaking up the magic in the parks, then I'm carrying it around with me somewhere in our A2 Wing!
