January 5, 1967 ~ April 15, 2019

Born in: Columbus, Indiana
Resided in: Littleton, Colorado

Diane Lewellen Carlson was born in Columbus Indiana on January 5, 1967 to John and Barbara Lewellen and proud older brothers Mike and Brad. John and Barbara decided Colorado was the right place to pursue their American dream and when Diane was 2 they moved to southwest Denver in 1969 with hope and promise on their side.

The family thrived in Denver; Diane attended John F Kennedy High School where she excelled not only in class but also earning honors in Cross Country, Soccer and playing flute in the all city orchestra. Following high school Diane went to Fort Collins and attended Colorado State University, graduating in 4 years with a degree in finance in the spring of 1989. In August 1986, while at CSU, through mutual friends, she met Greg, a University of Colorado Student who had also attended a rival high school.  The two quickly became soul mates and fell in love; they celebrated that love in marriage on April 20, 1991.

Diane and Greg’s love grew profoundly with their evolving lives and three boys, Bryan, Evan, and John. Diane loved many things in life, most importantly teaching her boys about life, love and religion. She was passionate, protective, and vocal with her support when her boys played competitive sports including Football, Baseball, Basketball, and Hockey.  She was all in no matter what, even being ejected from the stands. Diane and Greg were always supportive of whatever adventures Bryan, Evan and John chose to pursue. Diane loved her boys, but was often outnumbered turning to unique ways to control them.  The boys remember her coaxing them inside by telling them “a storm was coming” regardless of the actual weather.

Diane loved to shop, especially for antiques, arts and crafts, and various religious icons, all of which filled her home. She had recently opened an antique booth in a local shop with her good friend Anne, where she had begun to sell many of her own items. Gambling was another fond hobby. When she had the time she enjoyed playing cards and slots, even having her favorite penny machines in Central City and Blackhawk. She enjoyed traveling with very found memories of England, Scotland, camping throughout the West, trips back to Indiana to see family and of course anything Disney. In 2018 she was able to travel to some of her favorite places including Santa Fe NM, Indiana to see family, and a bucket list trip on an Alaskan Cruise with Greg.

After a heroic battle with cancer Diane passed away in peace at her home in Littleton, Colorado with Greg, Bryan and John at her side, holding Greg’s hand as a bridge to Heaven and their second son Evan. Diane was preceded in passing by their beloved son Evan in July of 2015, her Father John and Mother Barbara.  She is survived by her best friend and husband Greg, their sons Bryan, and John; her brothers Mike (Michelle) Lewellen of Denver Colorado, Brad Lewellen of Golden Colorado, and  several nieces, nephews and grand nieces.

Memories Timeline


  1. Greg and family: Love and sympathy to all of you. May your gaze soon be lifted to brighter horizons while never forgetting.

  2. Greg, we’re heartbroken with you and will stand by you in the days to come. Diane has touched our hearts because of knowing her through you. All our love, Chris and Mark

  3. I am so sorry to hear of Diane’s passing. We worked together in the Trust Department at Norwest. I was new to Denver and the bank and Diane was my first friend. Coming from outside of Denver she introduced me to “Giant Breakfast Burritos”. She was such a kind soul and was so madly in love with her husband and I remember her telling me when she was pregnant with her first two boys. We had lost touch and it has been a lot of years. God Bless you all. She is whole again and with her son Evan.

  4. Greg, Bryan, and John: Words cannot do justice to the heartache you are all experiencing. We are so very sorry for your loss and are thinking of you during this sad time. I know Diane’s spirit will continue to shine through those lives she has touched. Please know that we are here to support you all through everything that may come. May God give you the comfort and peace that you need. With love and remembrance, Betty, Scott, Justin, Jessica and Alyssa Wilson
