He was born on April 13, 1943 in the Glen Park neighborhood of Gary, IN to the late John and Anna (Berdy) Kostelnik.

Alex was a man of devout faith, quiet strength, and enduring love. He was a 1961 graduate of Lew Wallace High School in Gary. As a veteran of the United States Navy, Alex served his country with honor and integrity, working in communications as a radioman. After his honorable discharge, Alex began his career at Inland Steel where he dedicated 38 years of service. After retirement, he worked for the La Porte County Council on Aging for ten years.

On January 12, 1963, Alex married his high school sweetheart and soulmate, Diane Armato. They were lovingly married for 54 years when she preceded him in death.

Family and faith were the cornerstones of Alex’s life. He was a dedicated husband, devoted father and grandfather; never missing an opportunity to support them in their individual endeavors. He created treasured memories with his children and granddaughter. He especially loved taking his granddaughter on camping trips and supporting her at volleyball games.

Alex was a member of Holy Family Parish, previously serving on the Pastoral Council. He was devout in his faith and led by example. He was especially devoted to St. Michael and St. Padre Pio.

He was an active amateur radio operator (K9KAN) for over 65 years, obtaining his license at the age of 14. He preferred using morse code, and spoke to over 175 countries from around the world. He was a member of the American Radio Relay League, LaPorte Amateur Radio Club, and DX Club. He loved collecting vintage ham radio receivers, along with finding new countries to contact. Alex was proud that he helped his son in obtaining his amateur radio license at the age of 13.

Alex was a car buff and restored a 1954 Chevy with the help of two close friends, Paul Mathes and Charlie Hicks. His car received numerous awards and accolades over the years.

Leaving behind to cherish Alex’s memory is his son Anthony (Darla) Kostelnik of Hobart, daughter Christina (Jonathan) Fields of La Porte, and granddaughter Diana Fields of La Porte. He was preceded in death by his wife and parents.
