The Meaning Behind the Name

Why Amma

In many languages, Amma means mother — the most sacred word, spoken first and felt forever. This practice carries that name as a promise: you will be cared for the way a mother cares. With patience. With warmth. With love that never gives up on you.

“My mother believed I could heal people before I ever held a stethoscope. Amma is named for her, and for every mother whose love has been the heartbeat behind someone else’s greatness.”
— Dr. Sreeni Gangasani, MD, FACC
