Dennis Lester

Sebenick

Dennis L. Sebenick was born in Saginaw, MI on June 15, 1944, but grew up in Redondo Beach and graduated from Aviation High School in 1962. He lived most of his life in Harbor City, CA. He had no problem talking to anyone and made friends everywhere he went.

In his youth, he was a competitive athlete. He played football, baseball, and competed in bike races and speed skating. His speed and red hair earned him the nickname of “Red Rocket”, a name that people used long after the hair was gone.

He started his professional life as a printer at Dennison Tag & Label Printer, but he honed his gift of gab working as a shoe salesman at Gallencamp. He went to the LAPD where he worked for 30 years and retired as a Sergeant in 1999. He was beloved by his partners and his trainees because he always took care of everyone around him.

With his knowledge of law enforcement and his ability to talk to anyone, Dennis started his own security companies, Executive Protective Services and Custom Protective Services. He was still working up until the very end because he loved what he did.

Dennis also believed in giving back to his community. He was a member of the Harbor City Little League Board for years and coached several teams there and in other leagues in the South Bay. He was also involved in the Elks Lodge.

It didn’t take much to make Dennis happy. He loved his family, his cats, and watching his favorite shows, Law & Order and Survivor. His favorite movies were Pretty Woman and The Bodyguard, and he loved John Wayne movies. He loved going to Dodger Stadium to see his favorite team. One of his bucket list items was seeing his team win a World Series game from his seat at the stadium, which he thankfully got to cross off his list multiple times.

Dennis passed away on October 5th, 2026. One day after his 29th wedding anniversary.

A beloved father, grandfather, husband, and friend, Dennis is survived by his wife Aleda Sebenick, children Dennis Sebenick, Tammy Poeske, and Jason Thorsett, daughter-in-law Gilda Sebenick, son-in-law John Poeske, ex-wife Alexandra Kubat, grandchildren Tomás (TJ), Roberto (RJ), Annika, Alexis, Levi, Breawna, Kermit, and Ashlee, and niece Leah Montz.

Preceding him in death were his parents, Lester and Dorothy Sebenick, and his son Chris Blade.

A Celebration of Life for Dennis will be held on November 7, 2026, at 3:00 PM at the DoubleTree by Hilton Hotel San Pedro - Port of Los Angeles. There will also be a Memorial Service held on the same day at 11:30 AM at Green Hills Mortuary & Memorial Chapel.

Dennis' charm, wit, and warmth will be missed by all who knew him. The world is a little bit grayer without him in it.
