On the precipice of the start of the 2025-2026 NCAA Swimming & Diving season, Penn State has added two new assistant coaches to their staff.
Tommy Johnson will join the staff as an assistant swimming coach while Trevor Sisson will join the staff as an assistant diving coach.
Johnson swam collegiately at NCAA Division III Asbury University, where he was a captain in the 2022-2023 season. That season, he earned seven Liberal Arts All-Championship Team honors, winning conference titles in the 400 IM and 200 fly. That was his third conference title in four seasons in the 400 IM.
Besides being captain, he was the vice-president of the student body.
After graduating, he moved into coaching for the Eagles, where he was a part-time member of the staff for two seasons. He also worked as an undergraduate admissions counselor.
“I’m thrilled to have Coach Johnson added to our staff,” said Bonewit-Cron. “His ambition and enthusiasm during the hiring process reflected what was wanted to fill the role. He brings with him an eye for detail and an aptitude for learning and leading that will help our student-athletes through their academic and athletic endeavors at Penn State. He will work primarily with middle distance and also be impactful in all areas of our program.”
Outside of collegiate coaching, he worked for three years as the 13-14 lead age group coach from 2020 through 2023 for the R.C. Durr YMCA while finishing his college career; and for two years with the Florence Hammerheads summer league team.
Sisson joins the diving staff after spending the 2024-2025 season as the diving coach at Toledo. Prior to that, he spent two seasons at Georgia Southern (2022-2024), and one season at Bryant University (2021-2022), one season at NCAA Division II Davenport University, and two stints at NCAA Division III Wisconsin-Whitewater (2014-2017, 2018-2019).
Sisson had big successes at almost all of those stops. At Georgia Southern, he coached Karlee Wells to four Sun Belt Conference titles in two seasons, two Zone B appearances, and a school record on 3-meter. At Bryant, he was named the 2022 NEC Men’s Diving Coach of the Year. At that year’s championship meet, Ben Prouty swept the springboard diving titles and earned half of the A-final spots as the conference’s dominant diving program.
At Wisconsin-White Water, he coached Sierra Becker to four NCAA Championship qualifications and an All-American honor in 2015.
Outside of college, he coached two Wisconsin high schools from 2018-2020 and was named the WISCA Division II Boys’ Dive Coach of the Year in both seasons.
He competed at UW-Milwaukee from 2010-2013 where he was a Horizon League Championship finalist and Men’s Diver of the Year as a freshman. He ultimately transferred to UWW and graduated from there in 2021.
The Penn State men finished 9th out of 9 teams last season in their first year under new head coach Hollie Bonewit-Cron. The women’s team finished 12th out of 14 programs.
Johnson is a new staff member after they only carried three swimming assistants last season, while Sisson joins Bill Williams on the diving staff, who is entering his second season with the Nittany Lions.
Penn State has not released their 2025-2026 competition schedule yet.
