Energetic and motivating, Jason Calanog was originally hired as an assistant coach at Texas A&M, on June 5, 2015, and has since been elevated to associate head coach.

Calanog's infectious positivity and attention to detail have paid immediate dividends as the Aggies returned to the top 25 at the NCAA Championships in his first season, flirted with the top 15 in his second campaign and placed 14^th at the 2018 meet. Every school record had been broken since Calanog arrived in Aggieland, with the longest standing record dating back to 2017.

In 2021, Clanaog helped guide the Aggies to new heights as they notched their first top-10 finish as a team at NCAA Championships since 2001, with the program's first individual champion, Shaine Casas, leading the way, earning CSCAA and SEC Male Swimmer of the Year. Casas became the fourth swimmer since 2000 to win all three individual events he competed in as he placed first in the 100 back, 200 back and 200 IM. The 800 free relay team of Casas, Mark Theall, Kaloyan Bratanov and Clayton Bobo matched the Aggies' best relay finish after taking third, while the 200 free relay team of Casas, Bratanov, Theall and Tanner Olson added a top-five finish at NCAAs. 

At 2021 SEC Championships, Casas became the first Aggie to earn the Commissioner's Trophy multiple times as he brought home three individual medals, winning both backstroke events and taking third in the 100 fly. The 800 free relay team ended Florida's years-long run in the top spot to claim the top spot, while the 200 medley relay team also made a trip tot he podium. 

Calanog helped guide the Aggies to a historic performance at the 2020 SEC Championships as the team matched its best finish at the meeting, taking second. Six individual school records were set at the 2020 SEC Championships, as well as four relay school records. The Aggies brought home 15 medals as Shaine Casas became the first Aggie to earn multiple golds at SEC Championships, claiming the 200 IM and erasing U.S. Olympian Ryan Lochte's SEC record in the 200 back. Casas was awarded the Commissioner's Cup, given to the top point-earner at SEC Championships. Benjamin Walker also had another historic performance at the 2020 championships. After becoming the first Aggie to earn an individual SEC swimming title in 2019 winning the 200 breast, Walker repeated in the event as a senior with a school record-setting performance.  

In dual meet action, the Aggies remained in the top 10 in the national rankings all season, moving as high as No. 4 in December and finishing with a 7-3 record, including an early defeat of then-No. 5 Ohio State to start the year. 

The Aggies experienced a breakthrough season in 2017-18, setting a school record with a runner-up finish at the SEC Championship and placed 14^th at NCAAs. Over the year A&M went 7-1 in dual meets, including the first victory over rival Texas in 55 seasons.
 
In 2016-17, the Aggies placed 16^th the NCAA Championships while tallying a 4-1 dual record.

In his initial season in Aggieland, Texas A&M finished No. 25 at the national meet, had two school records broken and compiled a 7-1 dual meet record, which was the team’s best in more than a decade.
