2012-2020: Mark Maxwell was hired to bring about a change of direction to the program. The Board of Directors under the vision & leadership of Mark Maxwell adopted the clubs mission & vision statement.

The team becomes a Level 1 club through the CRP (Club Recognition Program), a Safe Sport Recognized (certified) Club. BDST becomes the most competitive in the club's history by producing many state, regional, zone, and sectional champions who have gone on to collegiate swimming programs across the state during this time frame. BDST begins hosting their own USA sanctioned meets at the Dallas Aquatic Center & start attracting local teams across Oregon into the Dallas community for competition. Under the direction of Coach Maxwell, respect for our team and program has been gained & noticed by the USA swimming & Oregon swimming community.

In March, Polk County lowers into a "high risk" category allowing for the pool to open after BDST had been out of the water for six months. June 22nd vaccination rates reach 65% in Polk County for COVID-19 allowing the DAC to resume normal operations.
