MARK SLADEK

Mark Sladek, age 66, of Elburn, passed away quietly into the arms of his Savior, on Sunday, February 21, 2021, surrounded by the love and prayers of his family.

He was born December 21, 1954, in Lombard, IL, to proud parents, John and Jacquelyn (Zeigler) Sladek.

Mark grew up in Lombard and attended local schools. He graduated from Glenbard East High School with the class of 1973, and where he distinguished himself on the grid iron as an offensive guard.

He continued his education at Loyola University in Chicago, where he majored in Political Science and graduated with a bachelor’s degree in 1977.

He was united in marriage to Janis Doll on September 29, 1979. They were blessed with two children while they began their new life in Lombard. After he and Janis went their separate ways, Mark was lucky in love once again when he met Libby Henderson. They walked down the aisle in 2002, making memories with every step. They settled in Glen Ellyn for a time until they moved to Elburn in 2019.

His first job in the industry at AVSI as a salesman, but worked his way up the ladder, eventually becoming the president. His tenure lasted ten years before moving on to various companies for the next forty years. Sales stayed in his blood until his retirement from Richards Industries in Ohio in 2018.

Mark was a proud member and alumni of the Sigma Pi fraternity.

Mark was known for his honesty and his kind heart, both in business and his everyday life. He never met a stranger and often made friends from many different walks of life. A friendship with Mark was a friendship for life. Mark was a fisherman at heart and Canada was his playground, but anywhere he could cast a line shot to the top of the list. Smallmouth bass and walleye were his favorite adversaries. When he wasn’t in a boat or on the shore, he was watching all his favorite fishing shows on T.V. The only time he put his fishing gear down was to pick up a golf club, spending quality time on the links chasing that ever elusive hole in one. He appreciated all kinds of music but his heart beat to the tune of Classic Rock, especially The Who, Tom Petty, Heart and Yes. He also enjoyed following the exploits of hopeful contestants on The Voice and American Idol and as much as he loved his bands up on stage, he was no slouch himself. Mark made a name for himself in community theater. Going to the movies was always an adventure regardless of what was playing. A movie buff, Mark had a “director’s eye” and loved watching from that perspective, picking up clues and ideas, always talking about how he would make his own movies. His grandchildren held a place in his heart like no other, and he was always happiest when surround by his family who will never forget him.

He is survived by his wife Libby Henderson; four children: Todd (Wendy) Sladek, Claire (Michael Essig) Sladek: Andrew (Susie) Bochnovic and James (Allyssa) Bochnovic; three grandchildren: Ava, Riley and Koda; two sisters: Ruth Storey and Jan (Mike) Waas; three nephews, two nieces and a family of friends.

He is preceded in death by his parents, John and Jacquelyn Sladek.

  1. I have known Mark since 1973 when we were freshman at Loyola University of Chicago as well as Fraternity brothers in Sigma Pi. Mark was always a great friend and a kind soul. My Family’s thoughts and prayers go out to Libby and his children and grandchildren. He will be missed.

  2. I am so sorry to learn of Mark’s passing. He and I grew up in the industry together. I was with Xomox from 1979-to 1985 and Mark was with AVSI. We competed but he was always a gentleman. I pray that the Lord will comfort you in this difficult time.

  3. Libby – Although you do not know me I had the pleasure and the honor of working with Mark during the majority of his career in Industrial Sales. Mark always had a smile on his face and he was always glad to see me. I will miss him very much.
    I am very sorry for your loss and please know that my family and I will be praying for you during this most difficult time.

  4. I’m saddened to hear about Marks passing. My family sends our sincerest condolences to Marks family. I knew Mark as a competitor and as an Associate having worked along side with him for several years. One word that comes to mind to describe Mark’s character is PASSION. Whether in the work place or outside doing what he loved, he did it with full emotion and intensity. One memory I have was when he unintentionally snapped off a steel armchair he was sitting in due to an adverse and turbulent meeting we had with a supplier. I’ll never forget how red Marks face got. We all chuckled about it afterwards even though they were brand new chairs! I also had the pleasure of fishing with Mark several times in Escanaba which just brought joy to Marks heart to be out in the open water. Mark Sladek touched everyone he came in contact with. He leaves a lasting impression on me.

  5. Libby…my deepest condolences to you and the entire Sladek family. I knew Mark throughout my entire business career and always appreciated his character and business acumen. He was also my friend which I cherished even more so. He will be missed and am grateful to have known him. Rest in Peace Mark.

  6. Libby…my sincerest sympathies to you and the entire Sladek family. I knew Mark throughout my entire career and always appreciated his humor and his character. He was simply a good man and someone who enriched my life. He will not be forgotten. Rest in peace my friend.
