What a wonderful legacy Bill Waeltz has left us with!


Arnold William “Bill” Waeltz, Jr.

(August 5, 1952 – June 7, 2013)

Arnold William “Bill” Waeltz, Jr. went to be with our Lord on June 7, 2013, at home in Round Rock, Texas surrounded by his loving family. 

Bill was an amazing man. A dedicated husband, father, grandfather, son, brother, uncle and friend. 

He was a registered civil engineer with his own practice, waeltz & prete, Inc. in round rock, Texas with his longtime friend, Antonio “tony” prete.  

He loved watching Cardinals Baseball, the history channel, woodworking in his shed, and more than anything being with his wife and family.
