Erickson was a devoted attendant at the Celebration Church in Lakeville, Minnesota. He welcomed churchgoers with a smile, ensured everything ran well, and “never missed a beat.”

After Erickson passed away in December at 69, his fellow worshippers only learned about his meticulous collection of rare toy vehicles at his house in Eagan, Minnesota.

According to Lisa Lundstrom, the executor of Erickson’s estate, the collection, which also includes seven impeccably maintained running automobiles, consists of about 30,000 cars that cover every square inch of his home.

“I would assume it’s a four-bedroom house, but I can’t tell because of the cars,” Lundstrom added. “Cars are stacked floor to ceiling in the restrooms, hallways, and kitchen.”

Lundstrom, the organization’s chief financial officer, is the daughter of Celebration Church’s founding pastor. She asserts that he grew close to her family because the church acted as Erickson’s family, and he was an only child whose parents were both deceased.

After Erickson’s death, Lundstrom went inside his home for the first time and said, “I knew automobiles were his hobby, but he was very private about his house, and now I understand why.” He preferred to keep his collection a private matter.

The church has put Lundstrom in charge of selling Erickson’s collection of cars to someone who will care for them as much as he did.

In response to Lundstrom’s observation, “He had cans and cans of cleansers and dust cloths near a huge chair. I imagine he had a rotating program of cleaning everything and putting it back in its ideal spot.”

Lundstrom claims that Erickson had built-in bookcases for his toys in his home, as well as a brochure describing his collection of miniature cars. According to Lundstrom, Erickson, a civil engineer who began collecting cars as a young child, also saved the original boxes for each and every vehicle.

According to Lundstrom, the total worth of Erickson’s estate—which includes his home, antique miniature cars, and vintage cars—will likely be well over six figures.

The church will use these funds to expand its children’s and youth ministries. Lundstrom stated that although she has her church family and the desire to help others and bring people to Jesus, she has never had children or a family.

Lundstrom said, “We want to celebrate Dennis’s life and service with the money from his estate.” She will utilize this money to help issues close to his heart, such as cancer research and veteran care.
