He’s in a league of his own.

Former trash collector Rehan Staton is preparing to graduate Harvard Law School next month, and now he’s helping workers in the same position he used to be in.

Staton says he’s fundraised more than $70,000 for service employees after a fateful interaction more than a year ago. He recalls greeting a campus custodian who was shocked he even acknowledged her.

“Students would usually rather look at the wall than talk to me,” he remembers her responding.

He told the Washington Post he knows exactly how that employee felt — after all, he used to haul trash for a living before following his education dreams.

Staton comes from a family of sanitation workers, claiming he grew up, at times, with very little food and unreliable electricity.

“I remember what it’s like working that type of job,” said Staton, who formed a family-like bond with custodians, cafeteria employees and security workers at the Ivy League university.

“When I see them, I see me,” he added of his “aunts and uncles” who don’t often get the recognition he believes they deserve. “I view them as my equal. They are just my peers.”

Set to receive his coveted diploma in May, Staton made it his mission to give back — beyond the $100 Amazon gift cards he handed out to support staffers last year after his exchange with the custodian.

The Maryland native co-founded the non-profit organization the Reciprocity Effect, with the goal of honoring “unsung heroes” like those at Harvard.

He enlisted the help of his former employer, Bates Trucking & Trash Removal of Bladensburg, Maryland.

Assistant operations manager Brent Bates had encouraged Staton in his studies at the University of Maryland.

“I know what it feels like to be in a position where people would rather act like you don’t exist,” Bates, 31, told the Washington Post.

With the help of his own father, Bates donated $50,000 to the Reciprocity Effect and became a co-founder.

“I’ve never seen something come full circle like this,” explained Staton. “The same sanitation company that changed my life, I came back to them, and they said, ‘We’ll be right there with you.’”

Staton, who attended the prestigious university with the help of generous donors such as actor Tyler Perry, knows it takes a village.

“No one does it alone,” said Staton. “Just keep paying it forward.”

Fellow Harvard Law student Lla Anderson, 24, joined in as well, calling the support staff her friends. She said they have gone out of their way to buy groceries for her when she couldn’t afford them and invited her to a holiday celebration when she had nowhere else to go.

“The thing about Rehan and I, is we don’t come from privilege, and we’ve had these thankless jobs, and because of that, we see in a way that a lot of people don’t,” explained Anderson. “I think people try the best that they can, but they don’t really know really where to begin.”

A “thank you” note drive held in November drew over 250 students to pen support for the workers. Then, Staton fundraised over $70,000 with the help of fellow students.

“People were truly inspired to start taking things to another level,” said Staton, who hopes to continue his do-good work after moving to NYC for his new job at a law firm.

Staton and Bates officially launched the non-profit on Monday, throwing a banquet at the university in celebration of their tremendous work and honoring 30 support staffers with prized trophies.

“There’s a lot of prideful people that work at this university that do things that a lot of people wouldn’t have pride in doing,” said Brione Merchant, 43, who has worked in the university’s cafeterias for 16 years.

“To acknowledge those people is very important,” she continued, adding that the charitable actions are a “beautiful thing to see and be a part of.”

Anderson called the night “amazing” and “incredible,” saying it “felt like it was just the beginning” of what the organization is capable of.

“They weren’t serving; they were being served,” she added.

Perry, who paid Staton’s Harvard Law tuition, was thrilled by the news of his charitable efforts.

The filmmaker is known for his own generosity — he most recently gave $750,000 to low-income Atlanta seniors and provided free Thanksgiving meals to families in the area.

“I loved hearing about his project, because it’s often why I do what I do: give back to those that are overlooked,” Perry told the Washington Post. “I hope he carries that kindness with him through his life.”
