Jeffrey S. Margolis

January 6th, 2026

Jeffrey and I were best friends and neighbors 4th grade through middle school. We were blessed to reconnect connect again often in the past few years with hours of phone calls together. I’m very sad to hear of his passing and know that he was in such pain and now glad he is at peace.
I remember fondly us spending hours playing around the neighborhood, and video games together on my 80’s PC’s. He mentioned it was those days that helped inspire him to get into computers and have such a prosperous career.
I will miss dearly our rambling on conversations on tech and parenting.

Jeff is my oldest friend. I remember the day I met Jeff like it was yesterday (I bet many others do as well). Jeff made that kind of an impression. It must have been my first day at Grove Elementary in 3rd grade… playing four square at recess. I think we met in line, waiting to play the game. Jeff oozed equal parts friendliness and goofiness and made me immediately feel like we were good friends. Jeff had that way with people, I think, throughout his life.

In 2000 or 2001, Jeff helped me build my first custom gaming PC. I am now CTO of a software company, so I think in some very real way I have Jeff to thank for that.

Jeff was a sweet, witty, and incredibly smart person. I regret not being able to spend more time with him over the years.

I am so thankful to have known you, Jeff. I miss you, my friend.

To Jeff’s family and friends, my deepest condolences. May his memory be a blessing.

I am truly sadden to hear of the passing of my good friend Jeff. I know he struggled with health issues but we were all hopeful for a better outcome. We had gotten to know each other over the years through working together. Jeff had supported me in Canada, as my engineer. Jeff was brilliant and always challenged the norm if it did not make sense. He had a great sense of humour and very witty. I will miss him like a brother and we referred to each other as brothers.

Till we meet again, my friend!

Jeff and I went to high school AND college together. Spartans for life.
We stayed in touch and talked often until the Covid of it all. I’m so sad to hear this news. We spent a lot of time together throughout our lives. Always laughing and scheming to create media together. He kept me laughing.
I hope his family knows what a great human he was. And he really, REALLY loved being a father. He was so proud.
May his memory be a blessing.

Pleasant memories when we were both working having great conversation and enjoying dinner when you were in town.

I met Jeffrey fifteen years ago through our mutual friend, Brian Cullen, and we became friends immediately. Although our careers took us in separate directions for many years, we recently reconnected and began exploring his interests in drone technology and fine art. Jeffrey was exceptionally kind and supportive, and his love for his children and family was unmistakable. His generosity will always be remembered and will forever live in my heart.

I am beyond devastated to hear this news. I talked to him on Thanksgiving. He was so kind to me and helped me out in so many ways. I don’t know what to do without my friend. I will miss him more than I can put into words.

Jeff wanted something beyond special for himself and Wolfgang last year.
He gave me 100% creative freedom to make the most magnificent mens ring of my career. An opal Jeff obtained while traveling was utilized taking 6 months to finish. He believed in me and saw me for who I am. I wanted the best for him and being able to make the compass necklace for Wolfgang to cherish forever also brings me great joy.
Jeff’s energy & sense of humor was most refreshing in this sensitive world.
Fast thinking, bold acting and resilient. Miss you my buddy.
Much Love Wolfgang.
