About the company

Potts and Callahan roots are deeply entwined with Baltimore and the surrounding areas. The demolition arm of our company is a family whose roots go back to the great Baltimore Fire. The Potts family were in the construction business in the early 1900's eventually they joined with the Callahan's to form Potts & Callahan & is still run by the Callahan family. Today the company is employee owned, family run and Baltimore City based. One of the few that are still a union shop.
