Doolittle supports Operation Finally Home, a nonprofit dedicated to providing housing for U.S. military veterans and their families, and Swords to Ploughshares, a Bay Area organization devoted to helping veterans with housing and employment. In June 2015, when the Oakland Athletics Pride Night received backlash from some fans for the team's support of LGBT rights, Doolittle and then-girlfriend Eireann Dolan bought hundreds of game tickets, which they donated to local LGBT groups, and raised an additional $40,000 in donations. Doolittle is an ally and LGBT rights activist.

Doolittle was ultimately named A's closer on May 20. Doolittle was one of six A's players named to the 2014 American League All-Star Team; he faced three batters late in the game - striking out two.

Of his charity work, Doolittle told The New York Times: "When I was a kid, I remember my parents would say, 'Baseball is what you do, but that's not who you are' — like that might be my job, but that's not the end-all, be-all. I feel like I might even be able to use it to help other people or open some doors or explore more opportunities."

After pitching just 26 professional innings, 25 of those at three minor league stops in 2012, Doolittle was called up to the majors on June 5, 2012, against the Texas Rangers pitching one and a third inning while striking out three with all fastballs and none going below 94 mph. He quickly became a key bullpen piece as the top lefty specialist earning his first career save on July 21 against the New York Yankees. He served as a set-up man for A's closer Grant Balfour the rest of the way as Oakland went on to win the AL West on the final day of the season.
