Dennis James Reiss

Dennis James Reiss passed away June 7th, 2026, of a heart attack. Dennis was born in Anaconda to Ralph and Delores Reiss in September 1952 as the second of three boys. He attended St. Joes and Dwyer schools and graduated from Anaconda High School. He had several occupations throughout his years. He first worked for Hoscheid Masonry as a young man then at the Smelter and the Job Corps. He served in the Army, joining the Paratroopers 82nd Airborne with his cousin Tim Wyant in 1972 until his honorable discharge in 1975. He married the love of his life, Michelle Evans, in Coeur d'Alene, Idaho in May 1989.

Dennis was an incredible storyteller and could entertain someone for hours with tales of his hunting adventures and time in the Army. He was very generous and enjoyed giving gifts and spending time with the people in his life. He was a lifelong hunter and fisherman, first enjoying the outdoors with his father, Ralph, then his brothers Tom and Phil and cousin Tim. His favorite hunting partner was his brother Phil with whom he hiked the backcountry pursuing big game and wetland birds. In his later years he enjoyed ATV rides and lakeside BBQs with family including his special family members, niece Erin, her husband David and their sons Dean, Evan, and Ethan. He also enjoyed spending time with these great nephews whether exploring the outdoors or playing video games. He truly enjoyed Montana to the fullest.

He is missed by his surviving family members, wife Michelle Reiss, brother Phil (Margy) Reiss. Cousin Tim (Carmen) Wyant. Niece Erin Dobrinen (David) and great nephews Dean, Evan and Ethan. He will be also missed by his extended family members, neighbors and friends. He is preceded in death by his parents Ralph and Delores Reiss, brother Tom Reiss (Helen), and cousins Dave, Kenny and Tony.

His family wishes to thank the Anaconda Hospital ER staff and Anaconda Ambulance staff for their efforts and kindness.
