Dr. Wheeler “Mac” McGregor has spent more than 60 years at Arnold Engineering Development Center in Tullahoma where he has developed sophisticated technology ranging from projectiles to satellites.Though he officially retired several years ago, this AEDC senior scientist is still involved in a Missile Defense Agency satellite called NFIRE (Near Fields Infrared Experiment).While he has devoted much of his life to science, in the past 15 years he has devoted much of the income earned in that career to provide counseling to thousands of people through the Alliance for Community Outreach.The Alliance for Community Outreach was founded in Manchester in 1997 by a group of local citizens who saw the need for a faith-based ministry to serve the entire community. At that time, the ACO was staffed by Benny Benjamin, a minister known for his counseling skills. In 1999, Dr. Eban Gilbert became a part-time counselor in McMinnville while still working at Taft Youth Center in Pikeville.
