Steven Daniel "Dan" Rosier
September 7, 1955 - March 10, 2021
Tulsa, Oklahoma - Steven Daniel "Dan" Rosier, former longtime Tri-Cities resident, passed away in Tulsa, Oklahoma on March 10, 2021 due to respiratory complications after a several months-long battle with the long-term effects of COVID-19. He was born on September 7, 1955 in Lorain, Ohio to Herbert Rosier and Mary Deverick. He grew up in Lorain and graduated from high school there.
Dan received his Master's Degree in Computer Science and Math from Bowling Green State University in Ohio. His first job was with Battelle in Richland as a computer scientist. Over the next few years, he worked for several Hanford contractors until he "retired" and started his own business as a general contractor. Dan built several homes and garages from the ground up and he remodeled, painted, re-roofed, and repaired many others. He built decks, pergolas, patios, fences, and landscaped many backyards throughout the greater Tri-Cities area.
Soon after he arrived in the Tri-Cities, when Dan was living in West Richland, he volunteered to set up a computer system at City Hall in the early days of West Richland city government. That experience lead him to run for office and he was elected Mayor of West Richland when he was still in his twenties. Over the next few years Dan was involved with the Tapteal Greenway, Tapteal Foundation, West Richland Chamber of Commerce, and other community service projects, especially those promoting recreation and preservation of natural areas.
During his early years in Tri-Cities, and because he was always looking for a new challenge, Dan took flying lessons and earned his pilot's license. He loved flying in the sunny wide-open skies of Eastern Washington.
At Contact Helpline, Dan served on the Board of Directors and was an overnight volunteer telephone counselor. He was a friendly, helpful voice for many troubled Tri-City people in the late 1990's and early 2000's until the service was dissolved.
While living in the Pacific Northwest, Dan enjoyed boating on the Columbia and developing nature trails along the Yakima River. He hiked in the Cascade Mountains and he liked spending time at his cabin near Cle Elum Lake. Dan enjoyed playing golf, coaching and playing on softball teams, and was a frequent participant in annual Cable Bridge Runs. He ran in several Bloomsday Marathons in Spokane. Dan also completed a weeklong Cycle Oregon bicycle ride through Central Oregon.
As a lifelong learner, Dan was a frequent library patron. He liked reading books on a wide variety of topics including house designs, travel, humor, biographies, politics, history, and mystery novels.
Dan was the first person his friends called when they needed help moving, needed an emergency home repair, or needed a ride to the airport or to a medical appointment. Dan was always willing to offer his time and talents or non-judgmental ear to anyone who needed help or just needed to talk to someone.
Dan loved solving problems, building houses, traveling to new places, and meeting new people. He traveled throughout the United States and enjoyed an extended trip to Australia.
Several years ago he accepted the challenge of building a house for a family member in Texas. He returned to the Tri-Cities for a short time and then relocated to Tulsa to build a new home for his mother.
More recently Dan was working as an Inventory Management Representative for the Oklahoma Blood Institute where he was able to continue serving his community by ensuring the hospitals and clinics in the Tulsa area had the blood products needed for surgeries and emergency treatments.
Dan was preceded in death by his father, Herb. He is survived by his mother, four younger sisters, several aunts, uncles, nieces, nephews and cousins, and many friends in the Tri-Cities, Oklahoma, and Texas. He will be greatly missed by all who knew him.
Dan was laid to rest in Tulsa. At his request, and due to COVID-19 concerns, no service was held.
Memorial donations in Dan's honor can be directed to Tapteal Greenway ( or PO Box 2002, Richland, WA 99352) to support their ongoing mission to promote conservation, education, and recreation along the lower Yakima River. //
