Skating with a minor knee injury at their first Junior Grand Prix event, in Lake Placid, Samuelson/Bates won all three segments of the competition to win the gold medal overall. At their second event, they won both the compulsory and original dances, but placed second in the free dance, to win the gold medal overall. These medals qualified them for the 2007–08 Junior Grand Prix Final and also earned them a bye to the 2008 U.S. Championships. At the Junior Grand Prix Final, they placed third in the compulsory dance and second in the original and free dances to win the silver medal overall. At the U.S. Championships, Samuelson/Bates made their senior national debut. They placed fourth in the compulsory and original dances. In the free dance, Samuelson/Bates fell during a lift that had been inserted into the program for the senior program due to the different requirements between junior and senior level free dances. They placed 6th in the free dance and won the pewter medal, continuing their medal streak at the U.S. Championships. Their placement at the U.S. Championships earned them a trip to the 2008 World Junior Championships. At Junior Worlds, they won all three segments of the competition and won the title overall.
