How To Find Them

105 Allendale Rd #3203
King of Prussia PA 19406


In our opinion, when your job’s focus is to help others in need to find a job, you have a pretty amazing job! That’s how we feel at Kelly Services, the oldest staffing agency in the country, founded in Troy, Michigan in 1946 by William R. Kelly. They began as Russell Kelly Office Service which functioned as an outsource typewriting and evolved when a client’s secretary didn’t show up for work and the client requested a secretary to work in their office. This innovative company has been operating in Montgomery County since 1959 and recently opened a new office in the heart of King of Prussia on Allendale Road. We caught up with a few of their team members just days after their grand opening!

“The impact we have on people, on families is tremendous.” says Area Manager, Nancy Penkivech. “One of the stories that sticks out to me is of a mom who recently became a single mom, and hadn’t been in the workforce for a while. We helped her secure a job and the first thing out of her mouth was, ‘this is unbelievable…I can now give my little girl a birthday party”.

Stories like this are abundant throughout Kelly Services branches around the world, but what many do not know is the variety of industries and terms of work that Kelly has access to. The majority of Kelly Services employees go for temporary positions that can turn into a permanent jobs, but they also serve employees who just want to fill in for that person on vacation or sick leave. They work for a week, a month, etc, take some time off, then go back and do another gig next month. Kelly even have access to one-day jobs like working at the Convention Center for an expo.

This level of flexibility extends to their clients as well, but what really sets Kelly Services apart is the advocating they do on behalf of the employees they place.  “We like to recognize our employees that have been working on a contract assignment and we push for them to get higher pay rates.” says Mariata Belotti, Account Manager in the Commercial Division. “We know every quarter, every dollar counts. We are an advocate for the successful employees we place and try to get them that pay increase. We appreciate the great job they do in representing Kelly”.

Kelly Services specializes in providing employees for office/clerical positions, manufacturing & logistics, inbound & outbound call centers, and finance & accounting just to name a few. Kelly Services is always looking for businesses that utilize agencies to staff and is constantly coming up with news ways to find the best employees possible. One of which is the advent of their new Kelly Van! This staffing agency on wheels will be parked at festivals, special events and other densely populated gatherings all around the country to offer information and registration to those looking for work.
