Tarrin’s journey with sensory processing disorders

Denice Mussillo wondered what life would be like for her son, Tarrin. At a young age, he was diagnosed with a severe sensory processing disorder (SPD) that made everyday life difficult.

A sensory processing disorder refers to the way the brain understands and responds to information from all of our senses – things like sight, sound, touch, or body awareness. When someone has difficulty processing their senses, it means their brain is working extra hard to sort and organize all of that incoming information. This can make everyday experiences feel more intense or uncomfortable than they do for others. For instance, a simple thing like putting on a shirt might feel completely different to someone with sensory processing challenges. A fabric that seems soft to most people might feel scratchy and painful to them.

“Even the most basic daily tasks were overwhelming for him,” said Denice. “There were moments when I truly never believed we would reach a place where he would be able to get dressed and go to school.”

That all changed when Denice and her family connected with Jeanne Ganz, an occupational therapist in Liberty POST, then known as Island Therapies. Jeanne worked closely with the Mussillo family so they could learn more about sensory processing disorders.

“Tarrin was able to confront all of his challenges with determination and support from his parents,” said Jeanne. “They were eager to learn all they could about Tarrin’s diagnosis so they could fully understand and help him at home. They were an amazing team!”

Pediatric therapists like Jeannie use a variety of techniques to support children with sensory processing challenges, incorporating enjoyable activities that help them integrate sensory input more effectively. They work closely with the family to understand specific challenges and incorporate that feedback into the therapy routine. Some of these activities include climbing, carrying weighted objects, or chewing foods such as bagels and gum. In addition, therapists help families develop a home program of sensory activities to help complement these efforts. Everyone processes sensory information differently, so the goal is to focus on each child’s strengths and abiliites.

“Jeanne didn’t just help my son…she helped us as parents, and she helped our family believe in a future we never thought was within reach,” said Denice.

His determination and hard work paid off. Tarrin graduated from his high school with all honors in 2025 and was accepted into Hofstra University’s Honors College to pursue becoming a Physician’s Assistant. The young child who struggled with daily living is now pursuing a future in healthcare, ready to help others.

“It is a testament not only to my son’s hard work and resilience, but also to the life-changing role Jeanne played in his journey,” added Denice.
