Mario De Marco
December 15, 1943 ~ January 4, 2022
Mario De Marco, of Fairfax, VA, passed away on January 4, 2022 at the age of 78, after a short illness. He is survived by his loving wife of 18 years Catherine (Kay Gauzza) De Marco, daughter Kim (De Marco) Weiss, son-in-law Phil and grandsons Ian and Ethan, step-daughter Cari Fraser (Converse) and family (husband John and step-grandchildren Madison and Mackenzie), step-son Alex Converse and family (wife Hannah and step-grandchild Claire), sister-in-law Eileen De Marco, niece Maria De Marco and family, and other nieces and nephews living out of state.
Mario was born in Philadelphia, PA on Dec. 15, 1943 to Ernest and Philomena (Somma) De Marco, now deceased. The youngest brother of three, Mario was preceded in death by his older brothers Benjamin De Marco and Ernest De Marco.
Mario began his professional career at IBM where he started as a mail clerk and worked his way up to senior management. After retiring from IBM, Mario became founder and owner of a successful consulting company, CoreTech Consulting Group Inc. CoreTech provided information and technology consulting services to businesses throughout the US. CoreTech was listed #132 on the list of the fastest growing companies in America. Mario later went on to develop a master’s program for IT executives and corporate officers at Drexel University. He also became an adjunct professor for Drexel and taught an online class which he enjoyed very much.
Mario loved to travel especially by cruise and enjoyed many cruise vacations with his wife Kay, daughter Kim and family, as well as, several with his brother Ernie and sister-in-law Eileen. They traveled through many countries with Mario’s most favorites sites including Egypt, China, and Europe and he loved touring various towns and cities in Italy, reliving the memories of his ancestors. But he especially adored Paris because of his love for art, the people and the cuisine.
Thanks to his love for fine dining, in his later years Mario developed a passion for cooking. He watched the food network and several of his favorite chefs to get ideas for various meals, primarily Italian dishes and he treated his wife Kay, family and friends to his culinary creations.
Mario loved his family. He was a good husband and family man. In addition to his wife, his daughter Kim, son-in-law and his grandsons were very important to him. He shared in the boys’ latest endeavors (auto racing and cooking) and was very proud of them. He was also very proud of the two children (a boy and a girl) that he and Kay were sponsoring in Uganda.
Mario’s passing has created a great void in our lives and our hearts.
We will miss him every day. We pray that he has been reunited in death with his loved ones, especially his mom and brothers and that he is now resting in the arms of the lord.
A Mass will be held at St Timothy’s Catholic Church on Thursday, January 27 at 10:00. (13807 Poplar Tree Road, Chantilly, Va. 20151)
Following the mass, a private interment for only family members will be held at National Memorial Park in Falls Church, Virginia.

Although Jon and I recently met Mario in spring 2021, we knew immediately that he was resolute in his faith, loved and cherished Kay, his family and proud of his personal accomplishments. Proud but not pretentious. Having shared an Italian heritage, I in particular enjoyed our conversations on Italian cheeses (Locatelli), pasta , broccoli rabe and Rome. We are saddened that we won’t have the opportunity to become better acquainted with Mario but thankful for the brief time we shared. Rest In Glorious Peace, Mario. Our sincere condolences to Kay and family. Nancy & Jon Sampson
I only knew Mario through my early career at IBM. while I didn’t work directly with him, i always seemed to find him with a warm and engaging smile and outgoing personality for all. He just seemed to have a joy for life about him and loved a good laugh and connecting with friends. I pray that in time all the happy n loving memories Mario shared with his family will help bring comfort, healing and peace. while his physical presence may be gone, I have no doubt his spirit will live on in each of your hearts. May God bless you all and grant eternal peace to Mario.
Rest in Peace Uncle Mario. Thank you for all you had done for David and I when my father and mother passed. You were a kind, funny, thoughtful man. I will always remember your laugh and your smile. Our thoughts and prayers are with your family. Denise, Cliff, Jess and Ally Bonaventura
My Uncle Mario was my favorite uncle. Even though we haven’t seen each other much, we would talk on the phone for hours every month or so. He was so helpful with helping me though problems that I was having. He always had a good answer for me. We would also laugh a lot on the phone. If you new Mario, you knew he had a great laugh.I love to hear that laugh, and would always tell him he had a great laugh. He was the closes thing I had to my father, Ben DeMarco.I will miss him dearly. Love Rich & Kathy DeMarco.
Run and play and enjoy your eternal life Uncle Mario. Until we meet again with our Lord Jesus where we will Eternally live with him. Love you. Your niece, Kathy.
I grew up with Mario at Girard College. We were there for ten years. He was always someone you could talk to and enjoy time with. After graduation we wnt our separate ways. But in 1911 we got back together for our 50th Anniversary Reunion. Thatwas a nice time seeing all who attended. Recently Mario and Horace arranged get-togethers at a restaurant in NJ. Those were very nice; having a chance to talk and catch up; remember good and not so good time at the ‘Hum’. Mario – Rest in Peace. You will be missed but remembered fondly. Walt Dorsey Class of ’61.
