West Des Moines' Liang Chow has coached two students to Olympic gold: Gabby Douglas in London and Shawn Johnson in Beijing.
Chow doesn't have a sure thing for Rio, but it appears Johnston High School's Rachel Gowey is peaking at the right time.
The 18-year-old just finished second in the all-around at the U.S. Classic.
Now, she has to keep it up at the P&G and make the Olympic Trials.
Channel 13's Michael Admire reports on Gowey's preparations.
