Obituary

Larry Thomas Dennison, 82, of Chandler, Arizona, passed away on June 17, 2026, in Chandler, Arizona.

Born on October 16, 1943 in Keokuk, Iowa, he was the son of Thomas Sidney Dennison and Alice Virginia Dennison (Smith).  He grew up with several members of his immediate family in Keokuk and eventually made his way to Lee’s Summit, Missouri.

Larry graduated from Lee’s Summit High School in 1961 and went on to have a fulfilling career as a Millwright at Bendix Corporation, General Motors, and then Amazon.com. Outside of work, he was deeply passionate about Freemasonry, pursuing family genealogy, BBQ brisket, his Arizona Rattlers & KC Chiefs, & he didn’t miss many NASCAR races! 

Larry was known for always having a witty response and an open ear to offer opinions.  He had many friends over the years with whom he made many fond memories.  He had a generous spirit and would always think of others before himself, especially when it came to his grandchildren and great grandchildren.  His boisterous laugh brought immense joy and warmth to everyone he met. He will be deeply missed by all who had the privilege of knowing him over the years.

Larry was preceded in death by his wife, Janet Sue Dennison (Hopper), by his parents, Tom and Alice Dennison, and by his 4 beloved dogs Pokey, Jax, Kacee, and Luna.  He is survived by his children Rhonda Garner (Rich) of Harrison, AR; Tom Dennison (Leigh Ann) of Hollister, MO; and David Dennison (Stacey) of Phoenix, AZ; his grandchildren Jacy Garner of Harrison, AR; Jenna Lewis (James) of Branson, MO; Janie Loftin (Ryan) of Branson, MO; Adam Dennison of Springfield, MO; Lorelei Dennison of Phoenix, AZ; and many great grandchildren.

A private graveside service to commemorate, remember, and celebrate his life was held at Lee’s Summit Historical Cemetery.
