Farnen & Dermer, Inc.

Farnen & Dermer Inc. has been family-owned and operated for five generations. Its history dates back to 1902 when Leon Dermer opened its doors in the Pimlico area of Baltimore, Md. His son, Harold continued the family tradition, eventually taking over the business. He passed the company to his son Frank who, in turn, handed the keys to his two sons, Jay and Ed. Great-great-grandson Zack is the latest generation to join the company. Over the years, Farnen & Dermer Inc. has continued to serve the Baltimore and surrounding areas with the same level of excellence Leon established back in the early 20th century.
