firma działająca od wielu lat

I suppose I'm going to miss the old firm after all these years.

When dealers leave, they sometimes become clients of their old firm.

Members of the old firm continued with the new company.

His staff: one secretary who came with him from the old firm, where he had worked for almost 25 years.

What the partners might be thinking as they find themselves back with their old firm is another matter.

Burning up the last of your family money, running the old firm deeper into the ground.

Even if you were still in the old firm it would be much the same.

In tonight's premiere, he and some friends leave the old firm to start a new one.

No wonder the old firm hadn't produced anything new for years.

Well, don't you feel as though you're letting the old firm down a bit, me going into this alone?
