John D. Semlar, 51, died on November 17, 2020. John was born on April 22, 1969 to Doug and Marilyn Semlar in La Crosse, WI. He married Diane Groleau in Ocho Rios, Jamaica on May 25, 2010. She preceded him in death on August 20, 2017.

John loved music and he liked it loud. He enjoyed deer hunting with his son Joe and nephews at Bruce and Danelle’s in Hayward, WI. Fishing was John’s favorite past-time, with Diane catching the biggest fish; later his nephew Zander took over. Wherever John went, Leo his dog followed. John loved spending time with his son, Joe, and his family.

He was preceded in death by his wife, Diane, his grandparents, and his great nephew, Thomas.

He is survived by his son, Joe (Bria); grandchildren, Beau, Jessa, and Zoey; parents, Doug and Marilyn Semlar; sister, Geri Semlar and her children, Tia, Adam, Zander, and Maxene; aunts, uncles, cousins, many, many friends, and his ever-faithful friend and companion, Leo.

There will be a Celebration of Life at a later date.

    Johnny was very caring and compassionate friend. He had so much love to give. The loss of Diane left an unrepairable sadness . Leo tried to fix his broken heart. I hope your family knows how much John was loved. I truly will miss seeing John around. I take comfort knowing that he is with Diane in heaven. “Peace” was always his last word when parting… Peace for you Johnny… Peace is yours. Condolences to his family. Much love.
