Warren Simmons Brown

June 19, 1955 — April 9, 2024


Warren Simmons Brown was born June 19th, 1953, at Cheyenne Regional Medical Center in Cheyenne, WY, and peacefully transitioned Tuesday evening, April 9th, 2024, in Centennial, CO in the loving presence of his cats, Jessica and Zoe. 

A celebration of life begins at 1:00 p.m. Saturday, June 22nd at Bodhi Pilates, 1970 E County Line Road, Unit H in Highlands Ranch, Colorado with assorted vegan refreshments.

Warren was born in Cheyenne, Wyoming, to Ross Parkinson Brown and Jean Marie Brown (Simmons). He had one younger sister, Jeanette Marian Brown.  Warren’s father worked as an engineer for the state of Wyoming and the family moved to Rawlins then Douglas where Warren graduated high school in 1973 following in his father’s steps to attend the University of Wyoming College of Engineering. 

Warren was an avid learner his entire life and enjoyed his time at UW.  Warren would often recount stories of the antics of his fraternity, Acacia, that he joined in worries that he might not make friends.   Contrary to his fears, Warren acquired many great friends over his lifetime and truly impacted his community with his generous spirit and dedication to kindness. Warren was an attentive listener who extended interest in and acceptance of those around him.

Warren graduated from the University of Wyoming in 1977 and began work as a civil engineer in Wyoming and eventually found himself in Colorado working for Cigna where he attended the University of Denver to complete his Masters of Business Administration graduating in 1989. While Warren started out in Dillon, Colorado he found home and laid down roots in Centennial where he moved in 1996 and left an inspiring legacy of volunteerism and genuine concern for people and animals.

Warren took great care of himself and all in his vicinity and his hobbies and interests paralleled his spirituality.  Warren achieved a black belt in Tae Kwon Do, taught yoga classes, and practiced Pilates up until the day of his passing.  Warren was invested in his career and was considered one of Colorado’s top engineers in wastewater.  He ended his tenure as an environmental health consultant for the Adams County Health Department. 

Perhaps one of Warren’s greatest traits was his profound love for animals. Warren practiced vegetarianism and his ethics extended unconditional positive regard for all sentient beings and for the environment.  Warren has donated countless hours and dollars to various organizations and lived a values-based life that inspired all around him. 

He is survived by his nieces Janessa Banks of Rapid City, South Dakota; Jennifer Banks of Fort Collins, Colorado; his nephew Jesse Banks of Gillette, Wyoming; his great niece Hayden VonWerner of Rapid City, South Dakota; and many dear cousins.

He is preceded in death by his parents Ross and Jean Brown and his sister Jeanette Banks.
