All too often, the Carmelites of the Ancient Observance, or OCarms, get passed over in favor of St Teresa’s reform, the Discalced Carmelites or OCDs.

Many eremitical communities have aligned themselves with the OCarms because the Discalced said eremitical wasn’t part of Teresa’s vision. (They have, however, started accepting hermits and eremitical communities).
The OCarms have three women’s cenobitic monasteries in the US:
