Pastor Lain was born in Kansas City, MO and raised in a Nazarene Church parsonage. At age 13, his family became missionaries to Haiti after one year in Albertville, France. Don graduated from an international high school in Port-au-Prince, Haiti. He attended Nazarene Theological Seminary in 1988 and completed his Doctor of Ministry degree at Asbury Theological Seminary in 2009.
Prior to moving to Westlake, Pastor Don, along with his wife Nancy, pastored in up-state NY for 20 years, and Coshocton, Ohio for 5 years. In November 2013, he joined the Nazarene Foundation as Vice President of Gift Planning doing Financial Legacy presentations in churches throughout the Northeast and Upper Midwest. It is with great joy he re-enters pastoral ministry at Parkside Church of the Nazarene.
