In 1971, Ellis formed the PDR ("Pride, Determination, Resilience" or "Philadelphia Department of Recreation") swim team at the
Marcus Foster Recreation Center in
Nicetown, a neighborhood in
Philadelphia. The team is recognized as being the first
African-American swim team in the country, and Ellis is credited with helping break down stereotypes and diversifying the sport of swimming. His teams were highly competitive locally and nationally. They gained national recognition as a premier training program, sending team members to the
swimming trials for every
U.S. Olympic team from 1992 to 2007. In the 1980's, members of Ellis's swim club had received college scholarships for their swimming skills, set national age-group records, and a few had been selected for the Olympic trials. By 2019, over 100 of Ellis's swimming club members were estimated to have received college scholarships. Many talented swimmers, like Michael Norment, came to swim for Ellis' team because of his strong reputation as a coach. Norment became the first black swimmer on the U.S. national team, and later became a swimming coach himself.
Closing of Marcus Foster Pool Ellis coached the PDR team from 1971 until 2010. In 2008, the Marcus Foster Pool in Nicetown, where Ellis coached the PDR team, was closed due to disrepair to both the building and the pool and Ellis relocated his team, whose program was associated with Philadelphia's Parks and Recreation Department. By 2019, all but one of the Philadelphia indoor public pools closed, though most outdoor public pools remained open. For a period after the closing of the Marcus Foster Pool in 2008, and prior to 2010, Ellis conducted his co-ed swim team at the pool at Philadelphia's
La Salle University, and in the summer of 2008, taught swimming at Kelly Pool in Philadelphia's Fairmont Park. ==2007 Ellis biographical film,
