Mister Kleen has its roots in the community, and its leadership team and employees have been involved in multiple charitable activities over the last four decades. We are proud of our Kleen Team’s efforts to give back to the community, and we will be spotlighting a member’s volunteer work every month! 

In March, we are focusing on Giellen Medeiros, Mister Kleen’s Office Manager since October 2020, when she took over the position from her sister, Arianne Medeiros Downey. “I enjoy the fact that every day is something different – I’m not doing the same thing over and over again,” Giellen says.

Giellen grew up as the youngest of five siblings in Brazil, where they were raised by their mother. Arianne first moved to the DC Metro region in 2010, and Giellen followed her two years later. After being promoted from office administrator to office manager at another company, Giellen was hired at Mister Kleen when Arianne had to switch jobs for personal reasons.

As Office Manager, Giellen is called upon to solve problems large and small, and she tackles all of them with a smile on her face.

“I like helping people,” she says, and it’s something she continues to do outside of work hours. A self-described introvert, much of Giellen’s volunteer work leverages her technology skills while keeping her out of the public eye, for the most part.

This has included refurbishing computers for The Wilderness Technology Alliance. The refurbished computers, which have been donated by organizations and government agencies, are then given to needy individuals, nonprofits, and schools in the Metro DC area.

Closer to her home in Alexandria, Giellen also works with Momentum Collective Inc., a performing arts nonprofit that focuses on providing programs for low-income youth. When they put on plays, she will photograph the performances and then Photoshop the images to optimize them for promotional use.

Despite her reserve, Giellen also volunteers at community food pantries such as the Capital Area Food Bank.

“I actually went to a food distribution event in Arlington a couple of weeks ago with Yesenia Morales. It was very fulfilling, but it was also painful to watch because it was so cold and it started snowing, and people were standing there for like two hours just to get food. It was very painful to see. But I’m also blessed to be a part of that and try to help a little.”

“I just like helping people, it makes me feel useful and it makes me feel good. And you know, I have the time. I can do this and I love doing it.”
