Other information
After he was disqualified from the 4x100m mixed medley relay for multiple dolphin kicks at the 2019 Pan American Games in Lima, Peru, he released a video on social media outlining how he would change his technique, as he had been disqualified for similar instances in the past. "So, what I'm going to do to ensure that I never get disqualified again, to ensure that there's no grey area [and] I'm not doing anything illegal, is change the technique of my pullout back to the early 2000s-style pullout. Which means that I will be dolphin kicking with my pull-down simultaneously. That's what I'm going to do for literally the remainder of my career. I don't want anybody to feel bad for me or pity me, that's not what I'm saying. I just want people to understand that I'm human. When I hear things about me, it hurts. I hate the fact that I have this reputation, that I have a reputation for this kind of thing. I don't like it. I wish I didn't. But I have to own it." (, 20 Aug 2019)

His father was an alcoholic, and Miller was raised by his mother. He had little contact with his father, who died on Christmas Day 2015 while living on the streets in Ocean Beach, CA, United States of America. After he had won gold at the 2016 Olympic Games in Rio de Janeiro, Miller shared his father's story. “I felt like it was important that people know that despite me losing my dad six months before the Olympics, I was still able to come through and still able to achieve my dreams. Everybody has struggles. That's one thing that I went through that really sucked, that I had to deal with, that my family had to deal with." (, 14 Oct 2016;, 12 Jun 2019)
