Obituary
Johnny lived a life shaped by hard work, generosity, curiosity, and a deep passion for helping others - a true libertarian philanthropist. He carried a giving heart into every room. If you knew Johnny, you knew his bear hugs - the kind that wrapped around you and made the world feel a little less heavy. He had a rare gift for making people feel safe, understood, heard, and cared for. He was an analytical thinker and a dedicated doomsday prepper, always a few steps ahead with plans, supplies, and readiness - food, water, land, and guns. His preparation was his way of protecting the people he loved. That same sharp mind made him exceptional at his work. As a senior infrastructure engineer, he built and deployed automated systems with a level of skill that set him apart. Johnny felt most at peace outdoors. He loved wilderness skills, camping, and hiking - anything that let him rely on nature. He loved learning about other people's hobbies and interests just so he could take part in them. His own interests and hobbies were endless: 3D printing, painting, music, story-driven board games, feeding the homeless, political freedom, books, and silver and coin collecting. His desire for adventure and exploration never stopped. Johnny fell ill in January and passed away on February 8th, leaving behind a legacy of compassion, preparedness, curiosity, and love - a steady presence who cared deeply for the people in his life and his cat, Freyja. He is preceded in death by his father, John Dorn; his grandparents Booner, Mary, Nancy, and Bob; and several aunts, uncles, and cousins. He is survived by his mother, Marguerite Mary Dorn; his sisters Samantha Manning (Rob Lyons), Chrissy Hall (Jeff Hall), and Edwina; his nieces and nephews Hailey Kingery (James Cochran), Devine Dorn (Natalie Mathers), Kenzee Hall, Sal Manning, Addy Hall, and Liam Manning; and his great-nephew and great-niece Kohen Cochran and Quinn Cochran. He made the world feel safer just by being in it, and his absence is immeasurable - but so is the impact he made on every life he touched.

I was utterly shocked this morning when I saw the news of his passing. I considered him a very good friend. Dorn was an amazing human, so kind, unbelievably intelligent (I could listen to him talk for hours), inspiring, empathetic, truly one of “the good ones”. I hadn’t seen him in a long time as I’d moved cross country but we kept trying to make plans upon my return a few months ago. I am so sad I didn’t get to see him. I will miss him always.
I am so so utterly sorry for his family’s loss. The world is a darker place without him.

I'm at a loss for words. Since hearing this news last night, I'm flooded with so many wonderful childhood memories. We last spoke during football season, promised to get together as soon as things slowed down. This is the worst kind of reminder that tomorrow is not promised. A brilliant mind and the warmest soul, lost far too soon.
I'll forever miss you my brother.
Mary, Sam, Chrissy, and family, I miss you and I'll see you soon. In the meantime, I'm thinking about you guys. Love you all.

I worked with John when he was a young kid at McDonald's. He was one of my favorite kids to work with. He always has a smile and was always teaching me about techy things. I'm so sad about his passing. He was a beautiful soul who deserved to still be with us. My condolences, love and prayers for the family.

I had the opportunity and pleasure of working with Dorn (as we called him at work) while at Manta. He was a fun loving person with an easy laugh. He was sharp of wit and highly intelligent. I even had the chance to have drinks with him and the occasional dinner when I was out visiting the team in Columbus. My condolences to his family and close friends. He will be missed.
