The Jonas Brothers will bring their world tour to Cleveland to support their new album releases, and Sarah Dooley will be among the thousands of fans attending the concert.

Sarah, 13, is like most teenage girls who are fans of Nick, Kevin and Joe, but she has Cerebral palsy and has been confined to a wheelchair for most of her life.

“We have Jonas curtains, Jonas comforter, Jonas pictures all over the walls,” said Donna Dooley, Sarah’s mother.

Donna purchased floor seats to the concert several months ago, and her daughter has been undergoing intensive physical therapy. Sarah didn’t want to sit in the handicapped section at The Q, and she has been focused on using a walker for the first time.

“I mean, we’ve been working on walking for the past 13 years, but it just seems like it’s been coming together this year, and the past six months have been the most improvement she’s had,” said Donna.

Josh Palcic is Sarah’s physical therapist at the Achievement Center for Children in Westlake.

“She has a difficult time getting the motors to work. She has a hard time feeling some of the different things in her legs, understanding how to assume postures,” said Palcic.

“Her motivation comes with the Jonas’, and we do what it takes to get her motivated,” said Sarah’s father, Bob Dooley. “She has really excelled — walking, movements are better, and even a couple of words are coming out.”

“(If) she keeps making this progress, she’ll be able to take care of herself. That’s my goal,” said Donna. “And she wants to marry Nick!”

Tuesday’s concert begins at 7 p.m. at Quicken Loans Arena.
