Olympic gold medalist Kelsi Dahlia and her husband Thomas announced the birth of their second child, Milo Robert, via Instagram this week.
In a joint post, the couple wrote, “Our hearts doubled in size on 3/23 at 4:24 💙 the Lord answered so many of our prayers as we welcomed Milo Robert to our family at 8lb 12oz & 21.”
Milo Robert arrived just over three after older sister, Zia Mae, who was born on February 9, 2023.
Dahlia first broke out onto the international scene at 2015 U.S. Nationals, in which she won the 100 fly by over a second in a time of 57.27. She went on to win the event at the 2016 Olympic Trials, swimming a huge personal best time of 56.48 to make her first Olympic team.
In Rio, Dahlia just missed the final of the 100 fly by finishing ninth with a time of 57.54, just 0.03 seconds behind what it took to make the top eight. In addition to her individual swim, Dahlia also swam the butterfly leg in preliminary heats for Team USA in the 4×100 medley relay, which went on to win a gold medal in the finals.
The now-31-year-old went on to win four relay gold medals and an individual bronze in the 100 fly (56.37) at the 2017 World Championships in Budapest, and added one gold and two relay silvers at the 2019 edition in Gwangju.
Dahlia also accumulated 15 medals from the Short Course World Championships, all in either 2016 or 2018, 10 of them being gold. In Hangzhou in 2018, she won seven gold medals, including an individual world title in the 100 fly.
Throughout her years on the international stage, Dahlia collected a total of 30 Olympic, World Championship, Pan Am, and Pan Pacific medals.
Collegiately, Dahlia had a very accomplished career swimming for the University of Louisville. She swept the butterfly events at the 2015 and 2016 NCAA Championships, and also broke the NCAA, US Open, and American record in the 100 fly three times. She first broke the record by swimming a time of 49.89 in prelims at 2015 NCAAs, becoming the first woman under 50 seconds in the event. She then lowered it to 49.81 in the finals, and did so once again at 2016 NCAAs in a time of 49.43. Her record stood for four years, until Erika Brown broke it in 2020 with a time of 49.38.
Upon her retirement in May 2022, Dahlia started her coaching career as an associate coach at Notre Dame, where she was on staff from the 2022-23 to the conclusion of the 2024-25 season. She currently travels around the country to do clinics with age group swimmers.
Thomas Dahlia also raced for the Louisville Cardinals, having qualified to race both the 100 and 200 breaststroke NCAAs in his junior year. The couple met each other on the Louisville swim team and became engaged in March 2017.

Congrats Kelsi. What a lovely family and great pre-Easter blessing! 💚
Many congratulations to Kelsi and the whole Dahlia extended family!
