Longtime Lafayette, Colorado resident Daniel “Dan” Leszcynski, died Friday, March 8, 2019, at his home surrounded by his loving family. Dan lived 22 years with joy and passion in the face of his illness. He was 63 years old.

Dan was born July 7, 1955 in Spring Valley, Illinois, the son of Gertrude (Rocknowski) and Stanley Leszcynski. He grew up in Spring Valley and Peru, Illinois. Dan attended the St. Bede Academy in Peru and graduated with the class of 1973.

In March, 1974, Dan was united in marriage Kathleen Ruda in Ottawa, Illinois. They would renew their wedding vows at St. Mary’s Catholic Church in Peru, Illinois on January 25, 1977. The couple was blessed with two children, Sarah and Jason.

The couple moved to Denver where Dan attended Metro State and received his bachelor’s degree in 1983. He began his career with the National Weather Service working in their Sioux Falls, South Dakota, Limon, Colorado, and Springfield, Illinois offices before transferring to the Denver-Boulder office. He retired in 2014 after working as a meteorologist, I.M.E.T that spanned 30 years. He received numerous accommodations for training manuals he kept updated and for his work in the field at multiple wildfire sites. He was most proud of the assistance he provided to the firefighters at the Mesa Verde incident.

He also enjoyed hiking, softball and cross country skiing, particularly at the Breckenridge Nordic Center. He had a love for Spam and enjoyed listening to music, especially The Eagles.

I worked with Dan at the NWS in Boulder and served as the IMET there from 2000-2008. Dan was a great coworker - was always calm and the voice of reason during busy times at the office. His wealth of knowledge was of great help to me as a young forecaster when I arrived in Colorado. But, more importantly, he was a good friend who I think of often. We shared many of the same interests - spam and Monty Python - and he always made a day shift far more pleasant. The world lost a genuinely good person the other day, but I am consoled with the fact that Dan isn’t suffering.Right now, He’s probably making someone laugh in his next life. Peace and condolences to all of his family and friends, Rob
Dan is our good friend, loving father, husband and avid Nordic Skier at Breckenridge Nordic Center. We have known him and his dear wife Kathy, daughter Sarah, and son Jason over so many decades of mountain fun. Always a bright light in our day to see them arrive for time together outside in the winter months on Groomed Ski trails. Dan always had a positive word, easy laugh and smile for us. His kindnesses will be remembered as we grieve with and for his sweet family. All our love at this difficult time in your lives, The Dayton’s
Dear Kathy, Jason and Sarah: Dan fought a long and hard journey. Take comfort in knowing he now rests in peace. May our Lord console you and give you strength to continue your life's journey without him. We send all of you love and prayers. Al, Sue and Eric
Saying goodbye to someone we love is heartbreaking. May you find comfort in all the special memories shared with Dan. -Tad
I was a young student attending college at Metropolitan State when I was given an opportunity to volunteer at the NWS Office in Denver (located at Stapleton). I cannot say enough about the kindness, humor, and willingness to "teach" a young college student that Dan provided to me. Many of his "lessons" still reside deep within my core and I've passed those on to other young students over my years. He confirmed my desire to become an NWS Meteorologist. I will never forget his efforts (along with Koop), to teach me how to discern the amount of cloud cover there was out there. Yes, there's a skill there that many will never understand. I'm still haunted at how little I knew! lol. His laughter was contagious and his spirit to serve others was unfounded. Dan will be missed, but not forgotten.
To Kathy, Jason, Sarah and Stephen, I had the pleasure to visit Dan last Thanksgiving. He was in a great spirit, and enjoying tlhimself and company of his loving family. I was told, that's how he was all his life, even during a long battle with his health, he never complained! I wish you all peace, prosperity and remembering the great memories Dan has left behind. LOVE - Farzan
Dear Kathy, Jason and Sarah, My deepest condolences to you. My thoughts and prayers are with you. I have nothing but fond memories and will always cherish the time I spent with Dan. May he rest in peace. God bless and love always, paul.
I was saddened to see Dan’s obituary in our hometown paper, LaSalle-Peru’s News Tribune. I worked with Dan at Denler’s grocery store in Peru more than 40 years ago. We always had a good time stocking shelves and telling jokes. Sometimes after we finished a Saturday night shift at the store, we would go to Dan and Kathy’s apartment for a couple of beers, some pizza, and reruns of Monty Python. More laughs. Dan was a genuinely nice guy. After reading his obituary and other tributes, I was very happy to see he lived a full life both personally and professionally. Peace to Dan and his family and friends.
