Robert "Bob" McMahon, born March 6, 1937, passed away peacefully on September 15, 2025, surrounded by his loving wife of 69 years and his family, after a short battle with cancer.

Bob was a devoted husband, father, and grandfather—a man of quiet strength, steady character, and deep love for those closest to him. He owned and operated Venture Signs & RMAC Advertising, and was an active member of the Wilbur Smith Rotary Club, the Texarkana Chamber of Commerce (where he proudly served on the board), and the Texarkana Country Club (which he also served on the board).

A passionate golfer and enthusiastic traveler, Bob treasured time spent with family above all else. He was especially known for his legendary beef tenderloin on the grill, a tradition his family will always remember with love and laughter.

Bob is survived by his wife, Roberta McMahon, and their children: Scott & Lori McMahon of Eden Prairie, Minnesota; Sue & Dave Segura of Benton, Arkansas; Julie Brigham-Patchanian & David Patchanian; Steve & Vicki McMahon; and Jill McMahon & Alton Endsley of Texarkana. He also leaves behind eight grandchildren, fifteen great-grandchildren, and his two beloved cats.

A memorial service will be held at 3:00 P.M. Monday, September 29, 2025 at  Texarkana Funeral Home, Texas with Victoria Roberts officiating.

The family will receive friends from 2-3 Monday prior to the service.

The family extends heartfelt gratitude to Heritage Home Hospice, and especially to Chris Endsley, Kevin Holt, and Raye Adams, for their kindness, compassion, and care during Bob's final days.

In lieu of flowers, memorial contributions may be made to the Animal Protection League, 5820 Richmond Road, Texarkana, Texas, or St Jude Children's Hospital.
