Delivery model
Our own technicians — not a courier — deliver the equipment, set it up in the home, and teach the member and caregiver how to use it before leaving. Written instructions and a number that a person answers go with them.
In-home delivery and setup with patient/caregiver teaching. 24/7 emergency oxygen support after hours. Resupply via phone, form, or shop.diamondrx.com where applicable.
