To avoid being confused with nearby Redlands, the name was replaced with Bryn Mawr, and the depot added a post office in 1895.

In the 1900s, the town was prosperous along with the local citrus industry, and four packing houses were built in the area.

Local amenities included a general store, blacksmith's shop, pool room, service station, market, restaurant and workers' cabins.

The town slowly blended into nearby cities after the citrus industry was no longer an economic force in the area; a post office built in 1971 remains but the train depot was demolished.

Bryn Mawr Elementary School, the Loma Linda Broadcasting Network, and a historic Native American mission school and former Catholic church (now the Loma Linda Romanian Seventh-day Adventist Church) are located in the community, and Barton Villa in neighboring Redlands is just east of the area.
