Denny Andrews was born in Anacortes, Washington. As a child he lived all over the Midwest, finally returning to live in Oak Harbor, Washington. He graduated from the University of Washington with a degree in political science and a minor in history. While in college he also learned judo.

Denny joined the United States Air Force, where he qualified as an expert in small arms and developed an interest in antique weapons. His interest in the Old West and historically related events stems from the time he learned that he had a great-grandfather on each side of the Civil War.

He currently lives in Bellevue, Washington, with his wife, Lorna. They have four children and four grandchildren.

Denny has written two novels for AVALON: Luke Dawson: Wells Fargo Gun and its sequel, Luke Dawson: Wells Fargo Agent.
