Sienna Jagielski joined the Biola Women's Water Polo staff in the summer of 2022 as an assistant coach.
In her first season at Biola, Sienna helped lead the team to an extremely successful 2022-23 campaign. The Eagles posted 18 wins, while making movement in postseason play. At the WWPA Championships, the Eagles claimed the top spot for their first conference crown. The NCAA National Tournament bid did not go to waste, as Biola came out victorious in the opening round for the program's first nationals win.
Prior to jumping onto Biola's staff, Sienna was a standout athlete at Fresno State. From 2018-22, she thrived in the pool and in the classroom with three ACWPC All-Academic Team selections. Sienna also helped the Bulldogs to back-to-back Golden Coast Conference Championships, while becoming one of Fresno State's all-time leaders in career assists.
Sienna graduated from Fresno State with an undergraduate degree in mass communication and journalism and is currently working on a master of business administration.
