    Southwest Indian Missionary Association is an evangelical Christian missionary endeavor which was founded and directed in 1945 by Reverend Kenneth and Lucille Mendenhall in Phoenix, AZ. Its intention was a proactive Wesleyan Methodist ministry outreach to the Native American Indian people in Arizona.

Upon the passing of Rev. Kenneth his son, Earl Mendenhall, took upon himself the role of President. He faithfully served this ministry until our Lord also called him home.

Thus, Ken and Brenda Kelley steadfastly continued to operate SIMA in the heart of Phoenix for the following 14 years. Their last Sunday in the roles of President, Pastor, and Directors was on May 7, 2017. 

We are presently under the dedicated leadership of Robert Silas Griffin as the new President and Interim Pastor of the Missionary Chapel. We also count with a five-member board which governs SIMA, it currently includes Rodney Lovelace, Abigail Griffin, Jeff Morgan, Robert I. Griffin, and Jeffery Miller.
