The world is saddened by the loss of Dennis James Costlow, affectionately known as Denny, who passed away peacefully after a fierce and unexpected battle with cancer. His departure leaves an irreparable void in the hearts of those who knew and loved him.
Born on February 27, 1939, Denny was raised in nearby Hollidaysburg by his late parents Elvin James Costlow and Anna Mary Costlow (Baker), alongside his beloved sister Janet Walker (Costlow). Denny grew up in a household that emphasized the values of faith and honesty, which became the very heart of who he was. He personified a belief system that cultivated the importance of family, hard work, integrity, and loyalty that he lived and died by.
Denny was a proud husband, father, son, brother, and patriot. He is survived by his devoted wife of 60 years, Mi Chi Costlow of Waynesboro, PA and his children: Eva, Jacqueline, Vickie, Jimmy, Linda, and Vicky. Denny found joy in being the best Pappy to his grandchildren Mea, Nathanial, Dimitri, and Alice. His love for his family was infinite and unmistakable, thinking often of family located all around the country. Some of his fondest memories included time spent with his numerous cousins growing up and later with the extended family he faithfully interacted with until his last days.
A true American patriot, Denny served his country with distinction for 32 years in the United States Army. He retired with the prestigious rank of Command Sergeant Major from Fort Ritchie in Cascade, Maryland, a respected and admired figure amongst those who served alongside him. His leadership, discipline, and unwavering commitment to duty remain a shining example of military service at its finest.
Outside of his uniform, Denny was also an avid outdoorsman. He found joy and peace in nature, particularly through his lifelong love of hunting and fishing. His hands were rarely idle, he could always be found tinkering in his workshop, tending to his bountiful garden, and fixing up projects around the house.
To know Denny was to know strength, loyalty, kindness and an easy smile. He was an individual that was always willing to help anyone with anything he was capable of, without hesitation. His quiet dignity and honest nature were a source of comfort and reassurance to all those who knew and loved him. He was a man who could be counted on – steadfast in every storm, humble in every triumph, and generous in both word and deed.
Though he is no longer with us in body, the legacy of Dennis James Costlow will prevail in the lives he touched, the values he instilled, and the memories he helped create. His love, strength, and dedication to family and country will remain a beacon to those he leaves behind.
He will be deeply missed, but never forgotten.
