Warren, 73, was born on Christmas Day and lost his battle with leukemia on Veterans Day. Warren graduated from high school with the first senior class of George Washington High School in Denver and began his college education at the University of Colorado Boulder. He discovered a passion for construction engineering when he began working as a technician for the Colorado Department of Transportation (CDOT) in 1963. Warren was drafted into the U.S. Army in January, 1966. After basic training, he convinced his commanding officers to send him to Engineer Officers Candidate School at Ft. Belvoir, VA where he was commissioned as a 2d Lieutenant in the spring of 1967. For the next two years, he served as an officer and company commander with the 237th Engineer Battalion in Heilbronn, Germany until honorably discharged from active duty in June, 1969. After his discharge from the Army, Warren returned to full-time employment with CDOT. At the same time he enrolled in night school at the University of Colorado Denver where he was awarded his Bachelor of Science degree in Civil Engineering. After graduation, Warren became a registered Professional Engineer and Professional Land Surveyor in the State of Colorado. He continued to work at CDOT where his career took him many places in Colorado, including Colorado Springs as Resident Engineer and Pueblo as Deputy District Engineer. He retired from the position of CDOT Staff Construction & Materials Engineer in 1999 after 36 yrs. of service. During that time, he worked on many innovative and award-winning projects, including the Genesee Bridge over I-70, the Eisenhower Tunnel and the Belleview underpass at Santa Fe Drive in Littleton (a project accomplished in three days to move the highway under the railroad.) One of his most memorable moments was helping rescue people stranded on the I-25 bridge over the South Platte River and rebuilding the bridge after the flood of 1965. Before his retirement Warren was an active member of the American Association of State Highway and Transportation Officials (AASHTO) and a guest speaker at AASHTO conferences around the country. After retirement he enjoyed the challenges of golf, the stock market and square dancing as a member of the Foothills Senior Golf League, the American Association of Individual Investors (AAII) and the Square Halos Dance Club. Warren was preceded in death by his father Joseph L. Cramer and brother David C. Cramer and is survived by his mother Maude Ruth (Morgan) Cramer, wife Dorothy (Zimmerman) Cramer, son W. Christopher Cramer (Jamie Mueller), daughter Stacey Cramer and her partner James Kessler, granddaughters Emily and Morgan, brother Thomas Kent Cramer, nephew Andy, nieces Denise, Michaela & Mieka. A celebration of life will be held in the spring of 2017 on a date not yet determined.
