Obituaries | Gillette, Wyoming

Michael “Mike” Jay O’Brien, 63, passed away on October 29, 2020 from renal failure at Central Wyoming Hospice, Casper, WY.  He was born October 7, 1957 to Michael O’Brien and Ruth Blake in Farmington, New Mexico. In 1968, his family moved to Gillette, Wyoming for the oil fields. In 1969, his mother married Delbert Blake.

Growing up, Mike enjoyed wrestling, fishing, and having a fun time. He was most known for his ornery and comical personality. He worked most of his life in the oil fields.

Mike met Crystal Haukaas and had Trevor in 1995 and Melissa in 1998. He had lifelong friends who will all remember watching football games or NASCAR races together. Both friends and family will remember him as a fun time to be around.

In 2018, he became a grandfather, and nothing made him prouder.

Mike is survived by his daughter, Melissa (Kody) O’Brien; brothers, Larry (Dianne) Dayhoff, Randy (Carol) Dayhoff, Jim (Sharron) O’Brien, and Mark (Deborah) Blake; sister, Vonda (Dan) Jordan; grandson, Gunner Raleigh; and numerous nieces and nephews.
