On average 25 volunteers work at AHC each month. Volunteers come from many countries ranging from America, England, Australia, and Canada to Germany, Singapore, and Japan. Some work at AHC for a few days, while others stay a few weeks or months. Most volunteers have medical training and/or professional skills that can be used in AHC's clinical settings. Non-medical volunteers assist with administrative undertakings, English teaching, and/or the play specialists.

In the past, most volunteers were directed to AHC through Friends Without A Border, but increasingly volunteers approach the hospital through other professional networks (HVO and NVO). Tourists visiting Siem Reap often become short-term volunteers wanting to contribute a little to improve the circumstances in Cambodia.
