Early years

Howe teamed up with Chan in 2019, and the two decided to train at the Skating Club of Boston in Norwood, Massachusetts, coached by Aleksey Letov and Olga Ganicheva.^[5] In their second season together, Chan/Howe placed seventh at the 2020 Skate America and fifth at the 2021 U.S. Championships.

2021–22 season

Chan/Howe finished ninth at the 2021 CS Warsaw Cup. In January, they won pewter for fourth place at the 2022 U.S. Championships and were sent to the 2022 Four Continents Championships in Tallinn, Estonia. Ranked third in the short and second in the free, they moved ahead of Canada's Walsh/Michaud to take the silver medal behind fellow Americans Lu/Mitrofanov.^[6]

2022–23 season

The international pairs scene going into the 2022–23 season was greatly altered by the International Skating Union banning all Russian skaters in response to their country's invasion of Ukraine.^[7] With more podium opportunities for pairs outside of Russia, Chan/Howe began with a silver medal win at the 2022 CS U.S. Classic. Howe said that they were pleased with the outcome in light of injury troubles that had hindered their preparations.^[8]

Given two Grand Prix assignments for the first time, they won the silver medal at the 2022 Skate Canada International.^[9] They won a second silver medal weeks later at the 2022 NHK Trophy, qualifying for the Grand Prix Final.^[10][11] Despite a jump error in the free skate, Chan said they were "very happy with our skate."^[12] Chan/Howe struggled at the Final, finishing sixth of six teams.^[13]

Chan/Howe won the silver medal at the 2023 U.S. Championships, a new best podium placement at the national championships. Chan said they were both "really grateful" for the result.^[14] With national champions Knierim/Frazier declining to attend the 2023 Four Continents Championships in favour of a paid appearance at Art on Ice, Chan/Howe became the highest-ranked American team in attendance at a home ISU championship.^[15] In the short program, Howe fell on his triple toe attempt, but they still placed third in the segment.^[16][17] In the free skate, they overtook Canadians Stellato/Deschamps for the silver medal, their second. Chan called it "a special moment for both of us."^[18][19]

Chan/Howe concluded their season by making their World Championship debut, finishing fifth at the 2023 edition in Saitama.^[20]

2023–24 season

For most of the 2022–23 season, Howe had been dealing what was eventually revealed to be a torn labrum, which necessitated surgery in May of 2023. Chan and Howe resumed training together in July, and initially hoped to be ready to compete on the Grand Prix circuit in the fall.^[21] However, they subsequently had to withdraw from their assignments, as Howe's return to readiness proved slower than they had hoped. He would later say that the process was about getting "to a place where it’s like, oh, wow, this is what it feels like to actually be able to skate and not always be dealing and managing with pain."^[22]

Chan/Howe announced that they would return to competition at the 2024 U.S. Championships in Columbus.^[22] Despite Chan putting a hand down on the pair's throw loop in the short program, they won the segment by 1.29 points over Kam/O'Shea. Afterward, they announced their withdrawal in advance of the free skate. Howe explained that the short program was "a big success for us, and a huge milestone to our comeback, but we feel we want to take this time to continue to get healthy and set ourselves up for success."^[23]

Despite their withdrawal from the national championships, Chan/Howe were named to the American team from the 2024 World Championships in Montreal.^[24] They came twelfth in the short program, having had issues on their throw and spins.^[25] Thirteenth in the free skate, they finished twelfth overall. Chan viewed the result as "amazing for us," explaining that "last year we had a great debut. This year, we have a little bit different circumstances, but we're here and we're grateful."^[26]
