The Ewiiaapaayp Tribe's Little Ewiiaapaayp Reservation in Alpine, CA, hosts the Southern Indian Health Council, Inc. (“SIHC"), a California Public Benefit Corporation whose membership and Board of Directors is composed of seven federally recognized Indian tribes located in the County of San Diego, California (SIHC.org). The SIHC, Inc. receives funding pursuant to the Indian Self-Determination and Education Assistance Act, P.L. 93-638. See 25 U.S.C. § 450 et seq.

There are no Indian Health Service (HIS) or federally owned facilities under the jurisdiction of the California IHS Area Office. Instead, only tribal contractors operate programs from facilities that are owned by the tribes, health corporations or leased from private sources. The SIHC serves seven tribes: Barona, Campo, Ewiiaapaayp, Jamul, La Posta, Manzanita and Viejas, and residents of the East County. Programs and services offered are: medical clinic; dental clinic; community health; social services; mental health; senior home and substance abuse. The SIHC also operates a satellite clinic on the Campo Reservation.

The SIHC began as a satellite operation of the Indian Health Council located in North County. It incorporated in 1982 as a nonprofit, public benefit corporation, and moved to the Barona Reservation. In late 1987, the Ewiiaapaayp Tribe leased their Little Ewiiaapaayp Reservation in Alpine to SIHC, Inc. and the current permanent facility was built using two ICDBG funds awarded to the Ewiiaapaayp Tribe and one to the La Posta Band.
