A 35-year Mesa firefighter died on duty last week, it was announced.
Mark Keller, 62, who lived in Gilbert, was found dead the morning of May 6. Details of his death were not released.
âMy heart is with the Keller family in this difficult time,â said Fire Chief Mary Cameli in a news release. âWe are deeply saddened by the loss.â
According to the department, Keller began his career with Mesa Fire and Rescue in 1990.
His funeral is at 10 a.m. Thursday, May 15, at Mission Community Church, 4450 E. Elliot Road, Gilbert.
Kellerâs death hit home for Mayor Mark Freeman, a firefighter who worked with him.
âAs a retired Mesa Fire captain paramedic, Mark and I served together for many years, and I had the privilege of witnessing his dedication to our community firsthand,â Freeman said. âI extend my heartfelt condolences to the Keller family, his crew and all members of the Mesa Fire and Medical Department. Markâs legacy will continue to inspire us all.â
A day after Kellerâs passing hundreds of tributes and condolences had already poured into the departmentâs Facebook page and other social media platforms.
Keller was well-liked by all and described as jovial and supportive.
âThis breaks my heart,â wrote Joleen Stonebraker Stratton. âWe met him last summer when he responded to our 911 call when my son was choking on food.
âHe was the nicest person. At the hospital he invited us to come see him at the fire station that coming weekend.
âWe went there and he gave us a tour. We were so grateful for his help on one of our scariest days.â
Steve Petronsky called Keller a âgood-hearted manâ who will be missed dearly.
âMark and his team responded and helped give my mom another five years with us,â Petronsky said.
Daniel Pouliot said that some of his fondest memories during his short tenure with Mesa Fire âwere roving into and being tempted with Mark and the crews at Station 206.â
âThe brotherhood feeling was strong there at that time,â Pouliot said.â As I see how many posts and pictures are being shared, it really speaks to the type of man, friend and firefighter he was. I am really shocked and saddened to receive this news but it was a privilege to get to know him, laugh with him and work alongside him. Rest in peace Markâ
Andrew Hill said he was fortunate enough to have run a handful of 911 calls with Keller. âMark was such a nice human, very kind, sincere and cared for his patients and his community,â he said.
Mike Aagaard, a fellow long-time firefighter, said, âYou will be deeply missed and never forgotten. Your love for the job and passing on all your knowledge on to the younger generation says the type of person you were. You were one of the best. Weâll take it from here, my friend.â
