Few businesses are as closely identified with Broomfield as the one John A. TerHar helped established.

TerHar was born into the third generation of a south Denver family. He graduated from South High School.

TerHar worked for a Denver auto dealership for six year before purchasing a Broomfield dealership with his father-in-law, Hugo Sill in 1960. It was one of the first businesses on Highway 287 in Broomfield. Later, TerHar bought out Sill’s share of the business until his retirement in 1990.

Sill-TerHar Motors was nominated in 1987 for he Colorado Association of Commerce & Industry’s Colorado Business of the Year. It also won the Ford Motor Company’s President’s Award for customer service seven years in a row – only one of two dealerships in the United States to do so.

TerHar was one of the founders of the Broomfield Economic Development Corporation. He was a president of the Broomfield Chamber of Commerce and a member of the Broomfield Rotary and Lions Clubs.
