Dr. Warren LaVerne Johnson Jr., beloved husband, father, grandfather, and distinguished cardiologist, passed away on March 4, 2025 at the age of 81, with his family by his side. Born on June 9, 1943, Warren was raised in the small town of Lindsborg, Kansas, where he met his high school sweetheart, Becky Keyte. The two married in 1965, beginning a lifelong partnership filled with a shared love of family, travel, adventure, and Kansas Jayhawk Basketball.
Dr. Johnson earned his undergraduate degree from Bethany College, where he played basketball, before attending the University of Kansas Medical School. He completed his internal medicine residency and a cardiology fellowship at the Mayo Clinic in Rochester, Minnesota. Following his training, he served as Chief Cardiologist at Fort Bragg, North Carolina as a Major in the U.S. Army. During this time, he took advantage of his lunch breaks to obtain his private pilot’s license.
Dr. Johnson’s career in medicine was defined by his significant contributions to interventional cardiology. In 1977, he joined Cardiovascular Consultants at St. Luke’s Hospital in Kansas City, Missouri, where he later served as Chief of Staff. He earned the admiration and respect of both his patients and colleagues for his exceptional skill, patience, and empathy. Throughout his career, Dr. Johnson received numerous accolades, and his expertise was recognized nationally and internationally. He taught angioplasty techniques to physicians around the world, authored influential academic studies, participated in clinical trials, and played a key role in shaping the future of the field.
After 32 years of practice in Kansas City, Dr. Johnson established the first cardiology practice in Summit County, Colorado. He was Medical Director of Cardiology for Centura Health and Summit Medical Center and he was a founding director of the High Altitude Research Center before his retirement.
Warren was an avid outdoorsman. Warren and Becky summited 45 of Colorado’s 14,000-foot peaks, climbed Mount Rainier, Mount Kilimanjaro, and trekked to the base camp of Mount Everest. He loved alpine skiing and biking and completed two 55-kilometer American Birkebeiner ski races. His love for travel and adventure was a defining part of his life. He shared this passion with his family, treasuring every moment spent outdoors with those he loved. His greatest joy came from being in their company, especially when he followed his grandchildren down a bump run on Keystone Mountain.
Warren was known for his boundless optimism, infinite patience, sense of humor, wisdom and compassion. Whether in the hospital, on a mountain trail, or surrounded by his family, his kindness, humility, and gentle spirit left a lasting impression on everyone he met. His legacy endures through the countless lives he touched as a physician, mentor, husband, father, grandfather, and friend.
He is survived by his loving wife of 60 years, Becky, their three children, Heather Bergeson (Tim), Marci Leuschen (Carl), and Matt Johnson (Katie), his sister Margie Lloyd and his brother Daryl Johnson (Kola). He was Gpa to seven grandchildren: Joe, Will, and Anna Leuschen, Henry and Hailey Bergeson, and Siena and Graham Johnson. He was preceded in death by his parents, Warren L. Johnson Sr. and Margaret Keding Johnson Nelson.

Met Becky at Cederhurst where she visited Warren. What was most noticeable was her love and devotion to Warren. Warren was a joy to have experienced while visiting other memory care patients. While visiting it appeared he was always wanting to escape and figured out a few times.
We were so saddened to hear of Warren’s passing. We have many fond memories of our various activities together, especially staying with you both in Healdsburg and biking to various wineries. We will cherish that trip forever! Thank you for your friendship and generosity.
Wishing you healing in this time of grief and sending much love. May you be blessed!
I am saddened by Dr. Johnson’s passing. I loved his calm pleasant manner and our lengthy conversations about the mountains, his climbing and skiing adventures , his family and oh, we did discuss my heart and plumbing a bit. He was positive and assuring helping me quiet my concerns. I always felt much better about everything after our chats. He told me it was OK to have a bit of dark chocalate in the evening! I certainly miss our talks and his wonderful utlook on life.
We send our deepest condolences to all the family. May he Rest In Peace. Prayers especially for Marci & family🙏🏻

So sorry to hear of Warren’s passing. I enjoyed visiting with him when I would visit my mom, Kay at Cedarhurst Memory Care. I appreciate your family’s support of my mom when your family was there as well. The other residents there become your extended family.
Even near the end he was a kind and compassionate man caring about those around him.
Our deepest condolences.
An Amazing life and truly a gift to humanity!
Our love and sympathy to Becky and all the Family
Warren was a college and neighbor who put Saint Luke’s hospital on the map as one of the preeminent hospitals for angioplasty in the country but just as importantly for his daily demonstration of what a great father and husband should be. It was such an honor to be his friend.
Such a wonderful person. One of those people the world needs more of.
