Mark continued his career with Innovative Systems by telecommuting from his home office.

Mark is survived by his wife Mari, Custer, SD, two sons, Kevin (Stacy) Ascherin of Joint Base Lewis McCord, Washington, Derek Ascherin of Cheyenne, WY, granddaughter Abigail Ascherin, Washington, brother Brian (Trisha) Ascherin, Green Valley, AZ, sisters, Sheila (Jim) Heward, Bella Vista, AR, Carol (Jerry) Amerson, Des Moines, IA, Diane Haley, Raleigh, NC and Karen (Mike) Delicate, Rapid City, brother's and sister's in law, Mark (Kathryn) Davis, Rapid City, Marty (Amy) Davis, Black Hawk, Mike Davis, Huron, SD and several nieces, nephews and great nieces and nephews.  He was preceded in death by his son Alex Ascherin, his older brother Bruce, his parents, and infant brother Kevin, and his parent in-laws, Jerry and Marilyn Davis and sister in-law Jodi Davis.

Mark enjoyed biking, hiking, paddle boarding, four wheeling and anything outdoors as long as Mari and their three dogs, Maddie, Journey and Parker were by his side.  He had a servant's heart and was always available and eager to lend a hand to friends, family and anyone in need.  His laughter and enthusiasm for life was contagious and endeared him to all who had the pleasure of knowing him.
