During the early 1980s he was a founding partner of Metasoft, a software development company. He later returned to practice law in the firm Howard & Glenn, which now is Glenn & Elliott. He was very proud of his restaurant, Cafe de Manuel, where he spent many pleasant hours visiting old and new friends.

He loved playing golf and often could be found at Dave White Golf Course, where he enjoyed being a member of the men's golf association.

In addition to his wife, survivors include a son, Sarge Glenn of Chandler; two sisters, Mary C. Leverett of El Paso, Texas, and Mildred Bowers of Fort Stockton; and a brother, William Glenn of Fort Stockton.
