Marty Ray O'Brien

Marty O’Brien, 72, of Greenbrier, Arkansas, passed away on June 14, 2026, surrounded by the love of his family.

Marty was a devoted husband, father, grandfather, great-grandfather, brother, and friend whose larger-than-life personality left a lasting impression on everyone fortunate enough to know him. He was the beloved husband of Charlotte (Charlie) O’Brien and a proud father to Seth O’Brien (Kristen O’Brien) and Chris Williams.

Nothing brought Marty more joy than spending time with his family. He was a proud grandfather to Chloe Cooper (Jeremy Cooper), Christopher Williams (Madison Jones), Kolton Treadway, and Klayton Treadway. Marty was also blessed to become a great-grandfather to Asher Williams. He treasured every moment shared with them and took great pride in watching his family grow.

He was a loving brother to Rick O’Brien (Paula O’Brien) and Terry O’Brien, and he cherished the bond they shared throughout their lives. Marty is also survived by his mother-in-law, Virginia Williams.

Marty dedicated 56 years of his life to his trade as a Journeyman Pipefitter with Local 798 in Tulsa, Oklahoma. He also spent 10 years working for Quality Foods/PFG. He took immense pride in his work ethic, craftsmanship, and the relationships he built throughout his career.

Marty found happiness in life’s simple pleasures. He loved swimming in the pool, keeping his yard perfectly mowed, and cheering on the Razorbacks every chance he got. He never missed a game and rarely missed an episode of Law & Order: SVU. Whether he was gathered around a card table with family and friends or enjoying a backyard afternoon, Marty had a way of bringing people together.

Known as the life of the party, Marty kept everyone on their toes with his quick wit, humor, and unforgettable personality. His laughter filled every room he entered, and his presence made every gathering brighter. He had a unique gift for making memories that his family and friends will cherish forever.

Marty was preceded in death by his parents, Lloyd O’Brien and Wincel Bridges O’Brien. As well as his father-in-law Thomas Williams.

The family would like to extend their heartfelt gratitude to the dedicated care team at CARTI, Dr. Joseph Beck, the hospice team, and nurse Ashley Echols for the compassion, support, and exceptional care they provided to Marty throughout his journey. The family would also like to express their sincere appreciation to dear friends Cynthia Slamka Wilkes and Gary and Donna Parker for their unwavering friendship, kindness, and care during this difficult time.

Though his passing leaves an immeasurable void, the love, laughter, and countless memories he shared will live on in the hearts of those who knew and loved him.

Marty will be deeply missed and lovingly remembered always.

A celebration of life will be held at a later date.
