Meet Our Physician Associates
Lisa Banh, DMSc, PA-C
DFAAPA, CPAAPA
Associate Medical Director
Physician Assistant
Notary Public
Lisa has been practicing for 10+ years in the Inland Empire at Aspen Medical Group, Inc, and loves every aspect of her position. OB/GYN is a fun specialty, and we've been fortunate to have Pediatrics as part of our group, so she still gets to see the growing families! Her passion is also in surgery, which would be one of the few reasons that would keep her away from office time. She has 2 young children, who keep the other hours of her days busy. She is a fan of Disney and enjoys cruising and vacationing with the Mouse.
