Mike Grenier

April 6, 1959 — January 6, 2023

Thor Michael Grenier, ‘Mike’, departed this earth on Friday, January 6, 2023. Mike was born in Santa Marta, Colombia, S.A., on April 6, 1959. He grew up in Rindge and Jaffrey, NH and attended Conant High School, graduating in 1978. Mike joined the Navy shortly after graduation and served on an aircraft carrier, the USS Dwight D. Eisenhower, during much of his time in service to his country, which he loved dearly.


Mike was co-owner/co-founder of Hampsey & Grenier Associates, realtor, for over 30 years. He was active in the Jaffrey Community and was instrumental in starting the Jaffrey Sponsor a Highway Program, as well as being a long-time member of the Jaffrey Chamber of Commerce. Mike was devoted to his Faith and spent many years as Pastoral Council at St. Patrick Church in Jaffrey. Mike resided in Dublin and was a lifelong bachelor until getting married just over a year ago.


Mike was just a good guy. He loved his home in Dublin and he loved just about everything about the life he made for himself in New Hampshire. Mike was the type of guy that instantly made friends and if you needed anything he would give the shirt off his back. No act of kindness or generosity was ever too much for Mike. Mike was a true historian and an avid reader, especially of history books dealing with the civil war, Abraham Lincoln and the like. Mike will be missed and continue to be loved by so many people. Mike lived life his way. May God Bless him and keep him forever.


Mike is predeceased by his parents, Teresita Infante Grenier and Maurice J. Grenier.


He is survived by his wife Christine Waniak-Grenier. They met in 2019 and married September 5th, 2021. His stepchildren Zachary Padilla, Alexander Waniak, Olivia Bailey as well as her husband Drew Bailey he treated as if they were his own children. His grandson, Weston Bailey, he absolutely adored. Mike was an amazing husband, father and grandfather.

Additionally, Mike is survived by his sister, Sarah Poisson Grenier of Rye, NH, his nephew, Matthew Poisson of Rye, NH, his niece Emma and her husband Gage Marzloff of Albany, NY. Mike is also survived by his sister, Monique and brother-in-law Barry Tanner of Hancock, NH, his niece Kelly and her husband Lyle Backenroth of Raleigh, NC, and his niece Jennifer and her husband Matt Brower of Fredericksburg, VA, and many close friends.
