About Us

Our Mission
Arizona Emergency Medicine Specialists (AEMS) is a regional emergency medicine group that is committed to its hospital partners and the community they serve.
About Us
AEMS was founded in 2005 by a group of residency-trained emergency physicians that were looking for the opportunity to provide a high level of emergency care while residing in their local communities. Since the launch of AEMS, our emergency physicians have remained strongly opposed to working for large corporate emergency medicine groups.
We pride ourselves on high levels of patient satisfaction, low wait times, and a short average length of stay. We achieve this through implementing a team approach and working with our nursing and ancillary staff to maintain an excellent reputation in the region.

Innovative delivery of care starts with innovative physicians.
