December 10, 1936 ~ March 7, 2019

Born in: St. Louis, Missouri
Resided in: Lakewood, Colorado

Frank R. Sida, currently a resident of Golden, Colorado, passed away Thursday Afternoon, March 7, 2019. His family and friends can attest that he gave a heroic fight against the Alzheimer’s he fought. As the author Dylan Thomas penned, “Do not go gentle into that good night.”

Frank was born December 10, 1936 in St Louis, Missouri to Frank and Margaret (Duffy) Sida. He attended McBride Catholic High School. Before graduating he joined the US Marine Corps and developed a lifelong brotherhood with Marines the rest of his life.

After finishing his service he attended Washington University and received a BS in Marketing in 1965. His first and only job after graduating was with Standard Oil of Indiana which later became Amoco Oil Company. He held numerous assignments with ever increasing responsibility until he was offered his dream job: to start up from nothing a chain of independently branded Gas and Convenience stores in Salt Lake City named “Rainbo”. He proudly developed and operated that group of stores to be one of the largest chains in Utah. Each year while operating the Rainbo C-Store Chain he reached out and actively supported the Marine Corp Toys for Tots program. Frank was able to retire in 1994 and spent much of those years traveling in Europe with Kay his wife and actively participating in the leadership of St. Thomas More Parish. He also was an avid outdoorsman. Family and friends can attest to the camp he used to set up each fall in the Flaming Gorge, Utah area hunting and fishing where he welcomed all. He also followed in the steps of his grandfather, Rudolph Sida, in making sausage and passing that craft to his children.

Frank is survived by his wife, Kay, of 62 years, older sister Gloria (Chick) Hartwig, younger brothers Jim Sida and Nick Sida, sons Rocky Sida and Steve Sida along with daughters Amy Van Horn and Laura Sida. Equally important Frank is survived by 7 wonderful grandchildren whom he enjoyed teasing and spending time with.

A celebration of life service will be held at 10:30AM on Wednesday, March 20, 2019 at Christ the King Catholic Church, 4291 Evergreen Pkwy, Evergreen, CO 80439. A reception will follow the service. That afternoon Frank will be laid to rest at Ft Logan cemetery where he will receive a military burial. In lieu of flowers, a contribution to the Alzheimer’s Foundation of America would honor his life.

Memories Timeline


  1. I love you Franki, you were a blessings to all of us, your friendship meant a lot to Bill and me, I’m sure you are there with him. I will never forget you.
    My most sincere condolences to all the family.

  2. Our deepest condolences in this very difficult time.
    Revelation 21:3,4 “And he will wipe out every tear from their eyes, and death will be no more, neither will mourning nor outcry nor pain be anymore. The former things have passed away.”

  3. My husband, Ed Conforti, considered Frank his best friend. We lived across the street from the Sida’s in Sandy, Utah, and year after year, Frank tried his best to teach Ed, an Italian, how to grow tomatoes. Frank planted tomatoes in his front yard so Ed could see them when he drank his morning coffee — The two had a contest going and it was hilarious to listen to the two of them harangue each other. There are a million stories to tell about Frank — He was like no other and will always remain in the hearts of those who knew him as a devoted family man, ready to help others, a generous, outstanding Christian with a super sense of humor and the best friend ever! His was a life well-lived and I know Frank’s family takes comfort in that fact.

  4. My deepest condolences for the loss of Frank. I was fortunate to meet Frank a time or two and have heard many stories on his days at Rainbo. He was truly a legend. Rest in Peace.

  5. Dear Kay and family, our hearts and prayers go out to you and your family. Frank was a great guy and tireless worker. Your family’s legacy is engraved on St. Thomas More. We remember the twinkle in Frank’s eyes when he told a story. He was always so proud of his family and rightly so. He, along with his family, will be in our prayers. God bless all of you.

  6. Frank was simply the best of the best! A great friend who care about others, willing to help out , and ensure everyone was taken care before himself. Frank brought laughter and smiles whenever he was present, whether it’d be cooking for the St. Thomas-More’s annual festival, camping, tailgating at a sporting event, fishing, etc. His love for his family shined brightly, as he spoke proudly of them all, and his beautiful wife Kay he so loved and cherished. Frank, you will be missed but not forgotten, you have spread your goodwill on many of us, hold a spot for me Frankie, as you always have, until we meet again. Our heartfelt condolences, thoughts, and prayers to the family.

  7. I did not know Frank well, but I did know and admire his collection of “Wine Stoppers”. He did wonderful work and inspired me to try my hand. He was always willing to share his techniques.

  8. Having known Frank for about 40 yrs, I would best describe him simply as a good man who was always loyal to family, friends, and his faith.
    For about 20 yrs, Vicki and I and Norm and Chic would spend about 10 days skiing with Frank and Kay while staying at their home in Sandy. These were some of the most fun times of my life and the memories would fill a book. Frank always had a project or two in “The Shop” and we made lots of sawdust while having a couple cold ones and a cigar.
    He was a classic and one of a kind whose passing leaves a void which cannot be filled

  9. Dear Kay and family,
    We just returned from a trip and learned of Frank’s passing.
    We have fond memories of Frank’s impromptu visits. I think he came over mostly to visit with our grumpy beast, Bailey. She, out of character warmed to him easily. He calmed her with his loving kindness. They shared a mutual fondness. Frank made us proud of his military service in the Marines. However there was much debate over the contributions of Marines versus Navy!!
    Dick missed his lunch companion when the two of them decided to “break away”. We missed Frank when he first left home. However as sad as we are we are pleased he went home and will be forever in peace. Bless you Frank and may your family find peace knowing you are home. Dick&Glenda

  10. Dear Kay and family
    Our sincere condolences to all of you with the passing of your husband, father and father in law. In as much as we all loved Frank and miss him very much hopefully we can find comfort in the fact he is no longer suffering and soon will be united with our Mother who he loved dearly. We love you Frank and I will continue to celebrate our mutual birthdays on Dec. 10th as we have for the last 81 years.
    May God have mercy on you and provide strength to your family during this difficult time.
    Love Jim and Pam Sida

  11. Frank Sida lived a couple houses down from us in Sandy, UT! We loved his great sense of humor! His kind friendliness welcomed us to the neighborhood!! He told us that whenever you move into a new neighborhood, always walk around with a beer in your hand-that way you know who is fun and who isn’t-especially in Utah! Our son, as a young child, always ran inside when he saw Frank walking on the sidewalk and grabbed a beer from the frig to give to Frank! Sweet memories!! All our love to his family.

  12. Amy – I am sorry to learn about your father’s passing. He sounds like a wonderful man and I will pray for him and your family.

  13. Dear Kay and Family Sorry to hear about Frank’s passing. I have good memories of Frank growing up in Saint Ann’s.

  14. Dear Kay,
    We send you and your children and your whole family an affectionate hug in this sad circumstance. We too have lived and suffered a long illness that had affected Angelo Primo and taken him away. The comfort is to have always been close to those in need, all together, and to have been able to assist in the best way.
    We also pray with you from Italy for the soul of dear friend Frank. We are fortunate to remember him in joyful and serene moments. We will never forget his generosity and hospitality.
    We are close to you in the moment of remembrance and you are comforted by the fact that Frank left an example of a hard-working and honest life in which there was room for friendship and affection. The distance prevents us from being close to you in person but we participate spiritually by joining your prayers.
    With love,
    Flora and family

  15. Frank had so many talents including gardening, woodworking, and making delicious sausage, beer and wine. He also gave of himself and his talents for the good of others. St. Thomas More Parish was blessed to have him as a parishioner for many years.. He provided endless hours working on landscaping, gardening and the annual Festival. Our prayers are with you Kay and your family.

  16. Dear Kay and Family,
    I’m am so sorry to hear about the passing of one of my favorite people and mentors.
    Frank was simply the Best of the Best.
    You are all in my thoughts and prayers and I offer my deepest Condolences.
    He had such a passion for his faith, family, friends and life.
    He was a true hero and an example of what a man should be.
    I wish I had one more opportunity to have a Frank Sida meticulously crafted Raspberry Ale and His special whirly popped popcorn with him.
    He helped make our transition to Utah special and showed me that the midwestern spirit of hospitality was alive and well here.
    I will cherish the recipes, my wine topper and most important all the great memories.
    He was a friend like no other and Heaven gained a Great one!
    May God Bless You Kay and all your family during this difficult time and always.
    God Speed!

  17. Hope they like sausage in heaven. Thank you Frank for all you did for me as pastor of the parish you helped to build. God bless

  18. I am so sad to hear about Frank. He was an amazing boss, friend and person, I loved working with him at the Rainbo office. He kept the Rainbo stores immaculate inside and out, and if they were not up to his standards he would let you know. There is not a convenience store around then and now that could meet or beat his standards. I have great memories at Christmas time with the US Marine Corps Toys for Tots program and the summer Toys for Tots golf tournament, Sida sausage and planting flowers at Rainbo. He gave me the nickname Stach which stuck through my Rainbo years and beyond. My thoughts and prayers are with your family. You will be missed. Love you Stach

  19. Kay our sincere sympathy to you and your family. Frank was a great person, we will always remember his kindness.
    Gary, Jacque and Brandon Jackman

  20. I picture Tony welcoming Frank home, hoping somehow he’s brought his sausage with him to heaven. Frank’s kindness and humor were gifts to all of us at St. Thomas More. He and Kaye will always be remembered with gratitude and love. God bless you all.

  21. Kay, our deepest sorrow to you and your family for you loss of Frank. As you know, we go aback a long way to St. Ann’s Missouri. My strongest memory was the day Frank was driving and we had been celebrating something and ran into a tree. I suppose we had a drink or two. He was such a good man, as are brothers Jim and Nick. So many memories of the Sida family.

    Jim and Barb Howard

  22. Kay,
    Our deepest condolences go out to you and your family. I cherished the many years I had cooking Sida Sausage for Frank and his crew at The Days of Yore Festival. His twinkle in his eyes, smile and laugh will always be remembered in our hearts.
    God be with and your family.

    John and Selma Tomich

  23. Sorry to all the Sida family and friends. Even though we had a very cold winter Frank’s love remains warm in our hearts as Heaven opens their doors to receive him.
    Thank You Frank for serving our country. It takes brave men like you to keep all of us safe from people who want to do us harm.

    Ron & Marjorie Hartwig
    and Family

  24. Kay and family,
    We send our deepest condolences to you on Franks passing. I was so fortunate to have spent so many memorable times with you and
    your family growing up, and will always reflect back on Frank and his life with deference and a large smile on my face.
    From my extended summer stays at your home, to our countless fishing and camping trips, to our marathon tree cutting and brush
    hauling events in Sullivan (the tree cutting part was Franks favorite 🙂 ), Franks positive influence on my life will not soon be forgotten.
    Here’s to a small sip of “Franks Finest” to celebrate a life well done Uncle Frank!!! —- Semper fi —- God Bless you !!

  25. Amy and Family– I am so sorry for your loss! Your Dad, Frank, sounded like an amazing man! Blessings, love and lots of prayers to you and your entire family. Love,

  26. I am saddened to know of the death of one of my dearest friends. Some would say our senses of humor mirrored each other. Ii will forever hold you in my heart. I still talk of the pranks and one-liners we shared with each other. I will miss you and your goodness.
    Just like the evening in the mountains when I thanked you with a toast for being my friend, I toast you today for great memories. May you rest in peace.
    Jack Neeway
