Joshua Santillan

Santillan began learning to skate in 1996.[1] He teamed up with Olivia Oltmanns in September 2009.[3] The pair's international debut took place in September 2010 at a Junior Grand Prix (JGP) event in Graz, Austria. Their best JGP placement, 7th, came in September 2011 in Riga, Latvia.

Oltmanns/Santillan moved up to the senior level in the 2014–15 season. They finished 11th at the 2015 U.S. Championships. Trudi Oltmanns coached the pair in Minnesota.[4]

Santillan teamed up with Jessica Pfund in May 2015,[5] following tryouts in Florida and Colorado Springs, Colorado.[6] They decided to be coached by Lyndon Johnston in Ellenton, Florida and, early in their partnership, also trained with Jim Peterson and Amanda Evora.[2] Making their international debut, the pair won the bronze medal at the 2015 Autumn Classic International. Appearing as late replacements for Gretchen Donlan / Nathan Bartholomay,[2] they finished 8th at their first Grand Prix event, the 2015 Skate America.

Pfund underwent surgery in mid-2016 due to two torn ligaments in her right foot and returned to the ice three months later.[7] She and Santillan finished 8th at the 2016 Cup of China. Following the event, she had an amniotic stem cell injection to treat tendinitis in her anterior tendon and a bone cement injection for a chronic bruise in her talus bone.[7] In January 2017, Santillan had a strained rotator cuff in his right shoulder.[7] The pair placed 5th at the 2017 U.S. Championships.
