Neset was born on December 7, 2005, in Minot, North Dakota to mother Cheri, a dental hygienist and skating coach, and father Kris, a civil engineer.

They married in Santa Fe County, two days after Neset's 17th birthday, with her and Markelov's mothers acting as witnesses.

[3] Neset became interested in taking up skating at the age of three as her mother was involved in the sport, and her father was a college hockey player.

A native of Volgograd, Markelov chose to relocate to the United States to partner with Neset in March 2020, just before the COVID-19 pandemic curtailed international travel.

[6] The following month, the team debuted on the ISU Junior Grand Prix circuit at the 2021 JGP Russia where they placed eighth.

"[9] Despite their gold medal, they were not selected for one of the three American berths at the 2022 World Junior Championships, being passed over in favour of teams with stronger prior international results.

[10] Neset and Markelov were initially scheduled to begin the international season at the Armenian stop on the Junior Grand Prix circuit.

[6] In January, Neset/Markelov successfully defended their junior national title at the U.S. Championships, despite a rocky rhythm dance which left them initially in seventh place.

[6] On the Junior Grand Prix, they won gold at the 2023 JGP Thailand, the first event on the circuit, by a margin of almost 17 points.

"[20] Heavy pre-event favourites at the 2024 World Junior Championships in Taipei, Neset/Markelov won the rhythm dance by 4.05 points over second-place Germans Grimm/Savitskiy.

They won the free dance as well, despite Neset losing her balance and putting a hand down on a choreographic lift, resulting in a technical deduction for a fall.

They noted afterward that the choreographic lift was a new element they had created three weeks prior, Neset saying it was "a bit sad that we couldn't show a super clean skate."
