Terry O’Malley Seidler: Love for Family and Baseball

By baseball standards, Terry O’Malley Seidler has always managed her own team. That’s just the way it is when you are the mother of 10 children. While parenting can be a full-time job, gracious and cheerful Terry always made time for many other activities – including ownership of the Los Angeles Dodgers with her brother Peter!

Her father was Walter O’Malley, the visionary Baseball Hall of Fame executive who was Dodger President from 1950-70 and Dodger Chairman of the Board (1970-1979). He became part owner in 1944. As a young girl, Terry attended Dodger games at Ebbets Field in Brooklyn with her two grandfathers – Edwin J. O’Malley, former New York City Commissioner of Public Markets, and Peter B. Hanson, judge in Brooklyn Domestic Relations Court – and a lifelong love of baseball began. She recalls attending the 1941 World Series as an eight-year-old.

 “The earliest recollection goes back to 1941 when Brooklyn first played the Yankees in the World Series,” she said. “Pop thought I was too young to make my debut at the ball park. But you should have seen his face when he came home! That was the afternoon when (catcher) Mickey Owen dropped a third strike (in the ninth inning which led to the Yankees coming back to win Game 4, 7-4, and then the World Series in five games).”

Because of Walter’s involvement with the Dodgers, she grew up around the game and became friends with many of its greatest personalities, from Jackie Robinson, Roy Campanella, Pee Wee Reese, Duke Snider and Gil Hodges to Sandy Koufax, Don Drysdale, Carl Erskine, and broadcaster Vin Scully.

Besides her countless friendships within baseball, Terry’s passion for the game has been evident for decades as she shares her extensive knowledge of its history, teaching her children and grandchildren how to keep score while attending games or on TV, and watching the players as a fan.

Terry attended grammar school at Froebel Academy, Brooklyn and graduated from St. Francis Xavier Academy in Brooklyn. Terry captained her high school basketball team and was involved in multiple sports, student council and club activities. Terry excelled next at the College of New Rochelle, New York, where she was elected freshman class president and Mission Queen as a senior, played basketball and softball and was a member of the student council in 1953-1954. Raised in Amityville, Long Island, New York, she enjoyed hobbies ranging from ice skating to swimming and sailboat racing. Terry was a member of the Narrasketuck Yacht Club, where she won many races and first prize in seamanship. After graduating from college in 1954, she served as executive secretary for the Dodgertown Summer Camp for Boys in Vero Beach, Florida for three summers.

The officiating priest was Cardinal James McIntyre of Los Angeles.

Upon the Dodgers’ 1958 arrival in Los Angeles, Terry worked as personal secretary for her father. While the Dodgers struggled in their first season in Los Angeles, as destiny would have it, Terry met her future husband at the May 4, 1958 Dodgers-Phillies doubleheader at the Los Angeles Memorial Coliseum. Terry was introduced to business leader Roland Seidler, Jr., the man who organized “St. Therese Parish Day” at the game. The two were married October 4 that year and started their large family. They celebrated 47 years together until Roland (Rollie) passed on June 8, 2006.

The items held by Walter O’Malley will be part of a sealed time capsule on the history of the Dodgers.

Beginning in 1978, Terry served on the Dodgers Board of Directors. Terry was named secretary of the Dodgers Board of Directors in 1981, continuing in that role through 1998. The Dodgers won World Championships in 1981 and 1988 while she was a member of the board. During that time, the Dodgers were the only sports organization to receive recognition on three occasions as one of Fortune magazine’s “100 Best Companies to Work for in America.” The first time they were named in the book of the same name was in 1984, and were included on the list of 100 in 1993 and again in 1997.

On Opening Day, April 10, 2012, the 50th anniversary of Dodger Stadium, Los Angeles, Terry O’Malley Seidler threw the ceremonial first pitch, following the role of her mother Kay, who had thrown the first pitch at Dodger Stadium 50 years earlier to the day. Peter accompanied his sister Terry to the pitcher’s mound.

On the 50th Anniversary of the opening of Dodger Stadium, Terry was honored by the Dodgers to throw the ceremonial first pitch on April 10, 2012. She was accompanied to the pitcher’s mound by her brother Peter, the former President of the Dodgers from 1970-1998. Their mother Kay threw the ceremonial first pitch to break the seal on Dodger Stadium’s inaugural Opening Day, April 10, 1962.

In 2012, the Seidler and O’Malley families with partners purchased the San Diego Padres. Terry’s son Peter Seidler represented the family and was longtime chairman and CEO. He died in 2023, leaving behind a revered legacy throughout the greater San Diego community.

Terry’s enthusiasm and boundless energy has enabled her to serve on many community boards, find time to be a Pasadena American Little League manager and aid countless charities. Her deep commitment and service to the Catholic Church is unparalleled.

Not only has Terry’s love of baseball endured throughout the years, but her thoughtfulness and love for others has too.
