Alison Van Vooren Lasell
September 17, 1965 - November 10, 2023
Alison Van Vooren Lasell - beloved and loving mom, wife, daughter, sister, aunt, niece, and friend - passed away peacefully at home surrounded by her family on Friday, November 10, 2023.
Ali was born to Barbara F. and Robert A. Van Vooren on September 17, 1965, in Davenport, IA. She graduated from Iowa State University with a B.S. degree in education and moved to Denver, CO, to pursue her passions for public education and living the good life in the Colorado Rocky Mountains. She received a masters degree in curriculum and instruction from University of Colorado Boulder and a type d: principal's license from the University of Denver. In Denver, she met the love of her life, John, playing on a co-ed ultimate frisbee team and they wed in 2004, going on to have two sons, Peter and Charlie.
Ali's public education career spanned 26 years - teaching 7th and 8th grade science and math at Adams 12 Five Star Schools. She loved it - and strived to inspire, motivate, and help each student understand that they have great potential as a student and as a person. As a humble and life-long learner, Ali reflected on her first teaching job, "These kids taught me everything I know about teaching, and I owe any professional success to them!"
In 2015, she was elected to the Jefferson County School Board as part of the recall election and served for one term. She also served as 1st Vice President for JeffCo Prosperity Partners for four years. Ali was recently recognized by the Jefferson County School Board with the "Our Communities: Our Legacy - Lifetime of Service to Public Education". She graciously accepted this award, acknowledging her slate and team of colleagues and supporters as a big part of this recognition.
Ali was a generous and entertaining host to family and friends, whom she deeply cherished. Ali was one-of-a-kind and everyone who knew her considered themselves very lucky and loved. She was the center of her family's life - and her sense of humor, laughter, kindness, and zest for life were infectious. As her two boys grew up, she was a dedicated chauffeur, cheerleader at their sporting events, teacher of life lessons, and problem solver of life challenges. The family enjoyed skiing, camping, hiking, sporting events, live music, tending to their bee hives and dahlias, traveling, cooking, card games, and family reunions.
In 2018, Ali was diagnosed with HER-2 positive breast cancer, which metastasized to her brain in late 2020, in the form of leptomeningeal carcinomatosis. Propelled by her positive nature, wonderful physicians, and the loving support of "Team Ali;" she beat incredible odds and gained three more meaningful years of life. She continued to have fun watching the boys grow, learning to fly fish together, walking the ditch trail and later the mall, listening to her music, and enjoying time with family and friends.
Ali is survived by her loving husband of 19 years John; her two devoted sons: Peter and Charlie; adoring father, Bob Van Vooren; sisters: Chris Van Vooren (Bob), Guff Van Vooren (Vicki), Sara Borger (Alan), Steph Herold (Doug), and Mardy Sackley (Chuck); brother, Scott Van Vooren (Ellen); and many nieces and nephews and grand nieces and nephews. Ali was preceded in death by her mother, Barb Van Vooren; and nephew, Thomas Scott Van Vooren.

I just learned of Ali's passing. We worked together at Adam's 12 Five Star School District. She was one of my supervising teachers. I'm very very sad to hear about this. I always admired her intelligence and her commitment and dedication to the field of education. I learned a great deal from her. RIP Ali. . Stanley Settle

John,
I am so sorry for your loss. Ali was charismatic and fun and you could tell that people loved to be in her company. I enjoyed talking with her about your outdoor frisbee endeavors and her time at Iowa State (my husband's alma mater as well). Take all the time you need and we hope to see you back at HQ when you are ready.

John, My sincere condolences to you and your boys. I remember meeting Ali at our company holiday parties years ago and I admired how she was actively working to improve education. I pray for peace to surround all of you, her loved ones, during this time of grief and remembrance.

I met Ali several times over the years at company events. She was always passionate and fun to talk to, and I know that she made material contributions to benefit and better our community. I have worked with John for over 12 years, and I have great respect for he and his family. I wish them strength, peace and solace during such a difficult time.

Ali was such a light to so many. I was blessed to be around her during my (what always seemed too short) time in Colorado. Wishing her family and wonderful extended family of friends all the best as we remember Ali and celebrate her life.

Bill and I were so sad to hear about Ali. I always enjoyed seeing her at the hubs' work parties and talking about being two-son moms and life in Colorado. I loved her holiday -hemed jewelry! I'm glad she got to spend quality time with all her family the past year and we will hold John and the boys in our hearts.

Ali was the best. I knew her through Jeffco and helped with her campaign. In addition to being a wonderful board member, she was willing to Read Across America in Jeffco classrooms with me. When she was diagnosed I shared my cheeseburger soup with the boys and they were greatly appreciative when I texted the recipe. She loved her family deeply and they are extremely blessed to have her. Jeffco will not be the same without Ali, however, we will keep her memory alive in all of our hearts. She made this world a kinder place to live! Kris Kraft
