Walnut Creek (and Ventura) David Lenehan III moved on from this world, on January 5th, 2025. He was 89 years young. David had battled lung cancer for many years.

David was a smart, accomplished and social man. He loved learning and being informed. And he loved collecting.

He collected coins, art, and friends. And he worked to keep those friendships alive. Proof of that lies in the fact that many ofhis friends can be traced back to his time in grade school.

David was born in 1935, in Los Angeles, California. He was the first born to Bessie and David Lenehan II.

Dave’s father, and the Lenehan family, moved to Los Angeles from the state of Washington. In his younger days, David loved traveling to Washington to visit family and experience the state’s natural beauty. Dave’s father, David Lenehan II, died when Dave was young. His mother later wed Byron Bagley, who helped raise David and his sister.

David graduated from Franklin High School, in the Highland Park area of Los Angeles. There he served in ROTC and excelled in several academic subjects.

David attended Los Angles State College (later, California State College at Los Angeles). While attending college, he began working for the City of Los Angeles, as a civil engineer.

Still in his early twenty’s, David was introduced to Patricia.

They married and had three children. He liked to take his kids to car shows, historical sites, swap meets, camping and motorcycle riding. And as an engineer, he liked explaining to his kids how the freeways came to be and how the pitch of the turns on the interchanges were determined.

After leaving his job with the City of Los Angeles, David began working for Bell Telephone. He spent the rest of his career working for them, and the company’s later iterations and subsidiaries, including AT&T.

Some years after his divorce from Patricia, David married Eva. Soon after they married, the couple moved to New Jersey, to be closer to AT&T’s Head Quarters. They lived in New Jersey for many years and David’s career took-off. He ultimately rose to the position of President of International Marketing, Asian Division.

After his and Eva’s divorce, David returned to California, finishing his career in San Francisco. He ended up staying in the Bay Area after retiring. He loved being in Walnut Creek and he loved his large home.

David was very strong willed. Though he had smoked for the better part of 40 years, nearing retirement, he had the fortitude to stop smoking, cold turkey. Likewise, after a serious health scare about 15 years ago, he stopped drinking.

A few years ago, David moved to Ventura, California, to be closer to family. In Ventura, he lived at an assisted living location, The Townhouse. At The Townhouse, David met and formed a new family, a chosen family of friends.

There he got involved and took on leadership roles with several groups, including the writing club, and the trivia group.

What else did David love? He loved cars, The Far Side comics, plaid shirts (just look in his closet), being organized, photography, travel, visiting friends, news, politics, history, reading, writing, scrabble, art, classical music and his many friends and family members.

David is survived by his sister, Diane; three children, Michael, William and Kristan; as well as seven grandchildren.

He will be greatly missed.
