A Weston volunteer firefighter who sustained a severe traumatic brain injury in an accident at his Wilton home in June 2018 is on the mend.  John Kaczmarczyk fell backwards on the staircase, fracturing his skull.  The 58-year-old was taken to Norwalk Hospital’s trauma center for emergency surgery.  Kaczmarzyk spent 3 months in an inpatient rehab facility to work on speech and balance as he dealt with partial paralysis on his whole left side.  With outpatient rehabilitation, he now just has a limp and hopes to take part in the Tunnels to Towers Walk next September to support firefighters and their families, affected by 9/11.
