For 56 years of his life, Jim Grohl has watched his city grow and change from the window of Jimmy's quick launch, glamping out onto East Broad Street.

Every time he tends to the hot dogs on the grill.

Thank God we an institution in the city, you know, well known everybody else comes in for the nostalgia, but the nostalgia.

My mother and grandmother both said, We are always here to make a living, not a killing.

So we always, family wise, always did it that way.

We're here for a living.

Jimmy's is one of several long standing businesses spread across downtown Hazleton.

Grohl says his family has kept Jimmy's mostly the same since it opened in the 1980s, but the city has certainly changed around them.

I would say our population almost doubled.

We were down, I think, almost 20,000.

Now we're probably a mid-forties.

So I think it's a different, different culture that's here.

Just down the street from Jimmy's Hazel Drugs has been the city's local pharmacy since 1868.

This is our 155th year.

So we're the oldest existing business in Hazelton, and we're also the oldest compounding pharmacy in America.

Hazleton's population has grown exponentially in the last several years, and along with it, Spears customer base.

A lot of the new residents in our community are used to local community service from where they were before, where they lived.

So a lot of them embrace the idea that we're local, that we're established, that we've been here a long time.

They trust us.

They feel better coming to a local community pharmacy on the corner that can offer delivery, that can help package their pills, that can help counsel them, and also can help deal with any language issues.

We do have a number of bilingual staff members, so people do feel very comfortable coming to us.

While Hazel Drug has been seeing a stream of new customers.

Jimmy's sees nostalgic generations of longtime residents stopping by.

A lot of times we have six generations coming in.

Know my great grandfather used to come in, my grandmother came in and my parents brought me here as a little boy, you know.

So a lot of people grew up here.

While the city evolves, both businesses say they have no plans to leave downtown.

While our own Hazleton future, I think, is to just deliver the same thing we've been doing, deliver quality prescription products to the Hazleton and its residents.

My two sons are also pharmacists.

They work in the pharmacy with us.

So I think it shows that our legacy is it's something that we're serious about.

We know we're not going anywhere.

We plan to stay here.

And as the community grows, we hope to grow, too.
