Our ACHC Accreditation

Oxygen Concentrator Store and American Medical ACHC AccreditationThe ACHC is a national organization that was developed to ensure smart, quality-focused patient care with clearly defined standards for in-home medical services. The ACHC dictates that to receive its accreditation a company must be represented as credible and reputable while being continuously dedicated to maintaining the highest level of quality and service.

Testing to acquire this accreditation is very rigorous and requires companies to be very transparent. As such, many companies choose not to pursue it or are unable to abide by its high standards due to their own business practices. American Medical has been proudly accredited since 2012 and will continue to provide excellent patient care demonstrated by our patient-focused care and commitment to excellence.
