Cassidy’s Run for the Kids 5K (and Fun Walk) – Canceled for 2020


After careful consideration, we have decided to cancel this year’s Cassidy’s 5K. We value our supporters, sponsors, friends and family so very much and would never want to put them in harm’s way or cause any additional financial strain during these difficult times.

We hope this year long “pause” is filled with good health, financial gain and happiness for all who have been so supportive over the past 8 years.

We will come back bigger, stronger and with more heart in 2021 for the 8th Annual Cassidy’s 5K.

As always – we thank you for support, your love and your friendship!

For those asking about a virtual race it, was considered, but for many reasons including a strong desire to maintain the overall integrity of this very special event, it’s not a direction we wanted to go in.

Cassidy Claire Nicholas

Cassidy was born in August 2012 with Treacher Collins Syndrome, a rare genetic disorder that was a result of a spontaneous mutation of the fifth chromosome causing malformation of her facial bones. Cassidy has a severe case of TCS. Neither her parents nor team of doctors knew she was afflicted with this syndrome before her birth. She was immediately intubated after birth as she was born with no viable airway and a tracheostomy was performed when she was just two days old. Cassidy was born with choanal atresia; there was no passage between her nose and mouth, micrognathia; her jaw is underdeveloped lacking hinges and growth sacs and mylar hypoplasia; she lacks cheek bones. In addition to these abnormalities, Cassidy also has bilateral microtia; which means she was born without ear canals, ear drums or ear bones. Her ear lobes are undeveloped and she is also missing an inner ear canal on each side. Fortunately, her cochlear nerves are intact and she is able to hear with the assistance of a soft band bone anchored hearing aid. Additionally, Cassidy was born with a cleft soft palate. After a six week stay in the Tufts Medical Center NICU, she went home with her parents, Eva and Jeremy. She has already undergone many surgeries and faces numerous more for years to come. Despite all of her physical shortcomings, Cassidy is an engaging, loveable little girl.

Last July, little Cassidy underwent her 8th and most complicated surgery to date. Her Craniofacial surgeons began the process of reconstructing her tiny jaw. Since her jaw was not growing and lacked hinges on both sides, they extracted rib bone and cartilage from her and sculpted hinges with it. Cassidy’s doctors implanted plates in her face so that the rib bone will rest against them and hopefully push her jaw forward. The hope is that this surgery will eventually result in her jaw bone beginning to grow which will result in the removal of her trach.

Because of the generosity of those who have donated in past years, Cassidy’s mother was able to take some time off from work to be with Cassidy during her jaw extraction surgery and recovery. They were also able to purchase needed medical supplies that are not covered by their insurance. The Nicholas family has their sights set on the future Medpor ear surgery Cassidy will undergo. Because of the significant amount of rib bone and cartilage that was used for her jaw surgery, there will not be enough natural material to construct ears for her. The Medpor process will begin in April when Cassidy will begin getting saline injections twice a week to stretch the skin where her prosthetic ear will eventually be. The surgery for her first ear is scheduled for July and her second ear will be scheduled for next year.

The 7th Annual Cassidy’s 5k Run and Fun Walk will be held on Sunday, June 2, 2019 at 11:00 AM at Sylvan Street Grille, 195 Elm Street, Salisbury, MA. We are interested in financial sponsorships as well as items that can be raffled off. All proceeds from this race will go directly to Cassidy and the Nicholas family to offset costs of her future surgeries, which, in addition to those aforementioned, include construction of prosthetic cheek bones as well as restructuring her nose and eyelids. With your help, Cassidy can look forward to living a life with a normal face, will you consider helping her achieve that?

One day Cassidy will know and understand the outpouring of love and support that she receives through this event. One day, she will thank all of you! Someday she will run along with all of her supporters!
