Danil Siianytsia

Siianytsia began skating in 2003 in Dnipro. He competed at the national level in Ukraine, but never received an international assignment. After moving to the United States to learn pairs with Oltmanns, he continued in men's singles for several seasons, before expressing an interest in competing only in pairs.[3][1] On switching nationalities, Siianytsia said: "I love representing the United States. I never got a chance to compete for Ukraine. But going out under Team USA has been pretty awesome."[1]

Siianytsia's first pairs partner was Jasmine Wong, with whom he won the 2017 U.S. juvenile national bronze medalist.[4] He skated in 2017–18 with Ariana LoPinto on the intermediate level, but did not qualify to the 2018 U.S. Championships.[5]

Siianytsia teamed up with Anastasiia Smirnova in mid-2018 after he found her profile on IcePartnerSearch and asked Oltmanns to arrange a tryout.[1] She moved from Ukraine to train with Siianytsia under Oltmanns in Shakopee, Minnesota. In their first season together, they won the novice bronze medal at the 2019 U.S. Championships.

Smirnova/Siianytsia made their junior international debut at 2019 JGP Russia, where they finished seventh overall. They then competed at the 2019–20 U.S. Pairs Final and won the bronze medal, qualifying them to the 2020 U.S. Championships. At the 2019 Golden Spin of Zagreb in December, Smirnova/Siianytsia earned their first international medal, silver behind Georgia's Alina Butaeva / Luka Berulava.

At the 2020 U.S. Championships, Smirnova/Siianytsia were third in the short program, but won the free skate to earn the silver medal behind Kate Finster / Balazs Nagy. As a result, they were named to the 2020 World Junior Championships team, alongside Finster/Nagy and Winter Deardorff / Mikhail Johnson.[6] Smirnova/Siianytsia finished tenth at the World Junior Championships.

After the COVID-19 pandemic in Minnesota caused their training rink to close, Smirnova/Siianytsia temporarily relocated with their coach to her old rink in Sioux Center, Iowa.[7] The Junior Grand Prix, where they would have competed, was also affected by the COVID-19 pandemic and cancelled.

In January, Smirnova/Siianytsia won the junior title at the 2021 U.S. Championships by over 20 points ahead of Isabelle Martins / Ryan Bedard and Valentina Plazas / Maximiliano Fernandez, despite Smirnova suffering a high ankle sprain on her right leg in practice the day before competition began.[8] Siianytsia reflected that they were "pretty excited" about the win and "hopefully it won't be our last one."[8]
