Dr. Daniel Floyd Keller

Dan leaves behind many loved ones including his beloved bride of 57 years, Marilyn Fuller Keller, his four children, Kathryn, Dan, Mike, and Jim, five grandchildren, Lisa and Julie Caldwell, Katelyn Keller, Ryan and Jamie Keller, as well as his sister Kathryn Keller Powell, and many nieces and nephews.

Dan lived a full and distinguished life. He graduated from Casady High School as part of the school’s first graduating class of five in 1951. He was Casady’s first valedictorian, earned honors on the athletic fields, and remained an active alumnus being honored as Distinguished Graduate in 1991.

It was during his high school years that Dan met and courted Marilyn, his life-long love. Dan went on to graduate from The University of Oklahoma in three years with Magna Cum Laude honors earning him entrance into the esteemed Phi Beta Kappa academic fraternity. Active membership in the Kappa Sigma Fraternity was one of Dan’s most treasured college memories, and he remained an active alumnus throughout his life.

Dan earned his medical degree from Washington University in St. Louis and subsequently served in the United States Army as a Captain and physician. Throughout his life, Dan maintained a fervent love of the U.S. Military. Following his service, Dan went on to complete a Fellowship with the prestigious Cleveland Clinic and honed his passion for the specialty of Pathology.

After serving as Chief of Pathology and Director of Medical Technology at Wesley (Presbyterian) Hospital, Dan joined Medical Arts Laboratory which was founded by his father Floyd in 1923. Dan served faithfully as physician, partner, and CEO of Medical Arts Laboratory for 27 years before retiring in 1995. During his career, Dan served as President of the Oklahoma Association of Pathologists, and was often sought out by physicians for his expertise.

Second only to his family and career, Dan’s greatest passion was for motor sports having attended the Indianapolis 500 on nearly two dozen occasions from 1952 thru 2009 with lifelong friends John Kamp and Devan Sharbrough.

Surpassing all of Dan’s academic and professional accomplishments were his roles as loving husband to Marilyn, and devoted brother to Kathryn, father, grandfather and uncle to his family.
