Kieran J. McMahon, 50
January 21, 2025
Kieran Joseph McMahon, 50, of Lancaster, passed away Tuesday, January 21, 2025. Born in Johnson City, NY, he was the son of Dennis R. McMahon and the late Jo Ann (Sheridan) McMahon. Kieran was the husband of Toni N. (Keller) McMahon.
Kieran was a very passionate person and when he loved you, there’s nothing he wouldn’t do for you. He was highly respected by his friends and family, and professionally. Kieran was a successful medical device salesman for more than 21 years, working most recently for Abbott Medical.
Kieran recently learned to fly fish, and he found great peace being on the water and in nature. He positively loved being on the Chesapeake Bay and would always say that was his “happy” place. Kieran loved to take hunting trips with his son and friends, and his joy on these trips was more about spending time with his son and his friends. He was also an avid Steelers and Notre Dame football fan. Additionally, one of his biggest sources of pride was dedicating many years to coaching for the Cougar Lacrosse team. He was an amazing coach and loved by his team. Additionally, some of his favorite times with his daughter was watching her play sports and escorting her to her Father/ Daughter dances and embarrassing her with the funny “chicken dance”.
In addition to his wife, Toni, Kieran is survived by his son, Devin M. McMahon, partner of Maura, of Harrisburg, and daughter, Aarin E. McMahon, partner of Michael, of Lancaster. He is also survived by many aunts, uncles, and a host of cousins. He will also be greatly missed by his 2 canine companions, Stella and Bubba, and cat, Bert.
Kieran was a very smart, successful person and loved adventure. Unfortunately, he suffered from a traumatic brain injury 6 years ago and was never the same. His pain and depression ran very deep. The family asks that anyone reading this to please reach out to anyone you think is struggling. You could really make a huge difference in someone’s life by just checking in with them.
Memorial Services for Kieran will be announced at a later date. In lieu of flowers, the family requests that memorial contributions in Kieran’s memory be made to Out of the Darkness Walks or to the Brain Injury Association of America.

To the family, we had the pleasure of meeting him last fall when he joined us for a bear hunt. He was such an awesome guy. From the first time I met him in the airport, right up throughout his hunt he was so upbeat and a blast to have in camp. We are so saddened to hear of his passing. I will forever cherish his happiness and joy he expressed when he came back after harvesting his bear. We all will miss you here in Maine. Rest easy our friend. Thoughts and prayers to the entire family, please know we are thinking of you all!
Brandon, Brittany & the entire AGS team in Maine!

Although I never met Kieran, I have had the honor to work with Devin for the last two years. If Devin’s attitude and calm demeanor are an example of the job that Kieran did as a husband and father – you did a wonderful job! RIP Kieran and our prayers are out there for your family Toni, Devin and Aarin.

Hello, this is Willem Blakely. I had the honor of playing under Coach McMahon. He was always optimistic, cheerful and uplifting. The one year i had with him as a coach was one of my favorite seasons on the field- he made the sport special. I am sure that he will be making differences from beyond the grave through the memories he instilled.

To Toni, Devin, Aarin and uncle Denny your husband/ father and son will be “GREATLY ” missed. Kiran was always so pleasant to be around and I always looked forward to seeing him on my trips to Lancaster or when he would come to cherry hill Nj. My regret now is that I didn’t see more of him over the years . My deepest thoughts and prayers will always be with him and his family.With much much love always. Joe❤️❤️

I had the honor of meeting Kieran in 2009 while I was running a hybrid vascular lab in York. We worked together for several years through many challenging surgical procedures and he was always a welcome resource. I immediately took a liking to him because that’s just how K Mac (as I always called him) was. You just liked him. I can’t imagine anyone knowing him and not liking him. Our paths took us in different directions and it had been years since I had seen him. A mutual friend told me when K had his injury and I was horrified. Very recently, our paths crossed again when I saw him at Harrisburg Hospital just a month or so ago. I was so very happy to see my friend again and we chatted up like it was yesterday. I am thankful to have had the chance to see him again. I am even more thankful to have been able to call him a friend. I’m sorry for the way things went for you K. You are loved by many.
