September 25, 1927 - May 1, 2013 Derrel Robben passed away on May 1, 2013. Born in 1937, he was 75 years old. Survived by sons; Michael (Hillary) Robben, Mark (Mary) Robben, son-in-law Jim (Kim) Tichenell, 9 grandchildren, and one great grandchild. Born in Kansas, and later moving to Colorado with his parents, he graduated Catholic high school and immediately went into the Navy. After a few years back in the states, he married and accepted a job with IBM where he found great success in their accounting / payroll division. Derrel loved the outdoors; from camping, fishing and hunting, he loved to be in the mountains or at his favorite lake with his family and friends. An avid poker player and "all-around" handy man, he always helped others and gave a lending hand to all in need. We love you and will miss you, until we are all re-united in heaven under Christ's unfailing promise.
