LAKE MILLS, Wis. (CBS 58) -- The Lake Mills Fire Department is mourning the loss of one of its own.

Capt. Mark Bentheimer, 55, died this week after battling leukemia for four months. He was the department's most senior captain.

"His passion was definitely the fire department, his family, his grandkids," said his wife, Peggy Bentheimer. "Basically, he was just the kind that every time he filled a room, it was full of laughter and jokes."

He had twelve grandchildren and three children. Alicia Tsikretsis and Christine Behling said it doesn't matter that they weren't blood related to Bentheimer. He was their dad.

"He never once said, 'These are my stepchildren.' He always said, 'These are my kids.' To him, they were his kids," Peggy Bentheimer said.

"He was a father figure, but he was also my best friend as a father," Behling said. "No day is going to be the same without him."

They'll remember the times he spent boating and tubing with his family out on the lake near his home in Lake Mills.

"He loved it. He loved being our dad. He loved being papa to our kids," Tsikretsis said. "We have younger kids who will never be able to experience that with him."

He was diagnosed with a rare form of leukemia in February. After a bone marrow transplant, they thought he was cancer free.

"We brought him home and he was so happy. They said he had a 70 percent chance of a completely healthy life," Peggy Bentheimer said.

But this week, doctors discovered the cancer had gone through the spinal fluid, and he died days just days later. His loss left a void not only in his family but in his department.

"I've learned a lot from Mark both personally and professionally," said Lake Mills Fire Chief Todd Yandre. "It's the personal things that I'll remember more moving forward ... to enjoy life, your family, grandkids: the things away from the fire service."

The loss of Bentheimer comes a year and a half after the department lost another fire captain. Capt. Chris Truman died Dec. 31, 2018 after he was hit by a car while helping a stranded driver in Madison.

"Losing Mark and Chris 18 months ago -- that's a third of my command staff -- two guys that were well respected by the members," Yandre said.

Bentheimer was a member of the department for 21 years. He enjoyed teaching CPR, and was an EMT with Maple Bluff, Town of Madison, Waterloo and Jefferson.

"He started at the fire department when he was 18 years old. So 37 years in the service between fire and EMS," Peggy Bentheimer said.

She said her husband also enjoyed teaching and training other firefighters, and his legacy will live on through them and the life lessons he taught those around him.

Through it all, his family and friends say they'll never forget how bravely he battled cancer.

"You never saw any fear in his face, in his voice. He was always upbeat and pleasant, and concerned about others. I don't think I've ever seen such bravery in person. I don't think I've ever seen somebody be so stoic in the face of death. I said this many times: He made cancer look easy," said Lake Mills Police Chief Mick Selck.
