Ashley Jahn has been added to Matt Kredich's Tennessee swimming staff and two prior coaches have resigned.
Lars Jorgensen, interim men's coach last season in the wake of John Trembley's firing, has resigned.
Jennifer Woodruff, assistant coach in the women's program, has left to focus on her young family.
Kredich was named head coach of a newly combined program in April.
Jahn was a graduate assistant at UT on the women's side from 2008-10. She spent the past two seasons as assistant coach at UNLV and Idaho, respectively.
"When we learned Jen was stepping aside to raise her family,'' said Kredich, "my immediate thought was we had to get Ashley back here. I feel pretty lucky to be able to get her.
"She has a lot of the same skills and a lot of the same demeanor as Jen, but she has a lot of unique skills of her own. She's done a phenomenal job the last couple years with UNLV and Idaho.''
Jahn swam at the Air Force Academy, graduating in 2003. She served five years in the Air Force as a Medical Service Corps officer before starting grad school at UT.
Kredich previously hired Bret Lundegaard as an assistant coach.
Dave Parrington, the 2012 SEC diving coach of the year, will return for his 23rd season at UT.
