David's coaching career began at the age of 15, when he was hired as the Junior Tennis Pro at the Nelson Tennis Club in Nelson, BC Canada. Over the next few years, he coached at facilities in Castlegar, Trail, Vancouver, and Kelowna. During his 4 years of university, he returned each summer to the BC Kootenays to run the tennis programs in Nelson, Castlegar, and Trail for 4 months, and also coached at clubs in the St. Louis area. Upon completion of his degree in Sports Administration, he returned to Lindenwood University to coach the Junior Varsity team during their 2009 season. He returned to coaching in Vancouver in 2010, and launched A.T.L.D in April of 2012. During 4 years of operations in Vancouver, David and his team of coaches became Vancouver's leading independent provider of tennis lessons, working with an average of 150 individuals per year.
Seeking a warmer climate, David moved to Chandler in July of 2016, bringing A.T.L.D tennis lessons to the Phoenix East Valley.
