"I will have a shower in every major city in New England," said Kelleher.
He has purchased one portable shower already, and is planning to purchase another next week for the Bangor area.
"I'm proud to say this is coming to Bangor where I lost my son," Kelleher said.
Travis Kelleher lost his life to drug addiction in 2016. That inspired Peter to give back and eventually create the Support the Soupman nonprofit.
"It's just a beautiful thing," Kelleher said. "To take this to where my board of directors and I have taken this...it's not stopping."
Each portable shower costs about $50,000. Kelleher spent some of Tuesday meeting with Bangor businesses asking for donations
"You just pick up the phone and you ask, and I'm not shy about asking," he said. "If you don't want to help I say get out of my way because this is something we're doing."
Kelleher says the organization is purchasing a charter bus in the fall to make an emergency shelter for the homeless and hopes to one day have a bus to do medical and dental examinations.
"There's more that we can do," he said. "You can't help everybody, but boy we can try."
