I'M NOT THAT
DAVID BERKOWITZ
Yes, we share a name. No, I've never been to prison.
I'm the marketing strategist, AI expert, and author. Not the serial killer from the 1970s.

David Berkowitz

True Stories
Real Moments of Confusion
These actually happened. Multiple times. Over decades.
The Grocery Store Checkout
In 1st or 2nd grade, my mom ran into my friend's mother at checkout. She looked at my mom's name and asked, 'Are you related to David Berkowitz?'
I really wish she'd said 'Yes, he's my son.' But I got my sense of humor from my dad. 🛒
High School Attendance
First day of class, teacher reading names: 'Abrams... Bates... Ber.... no... wait.... David Berkowitz?!?' Every. Single. Year.
At least they remembered my name after that. 📚
Summer Camp Terror
Parent at camp: 'We were scared to death to send our kids here.' The head counselor had to reassure parents that yes, that's really my name.
Nothing builds character like terrifying other people's parents. ⛺
Google's Mix-Up
Google once listed MY Twitter account as the official Twitter account for Son of Sam. Because that's definitely who should be verified.
Tech companies: maybe check twice before the blue checkmark? 🐦
The Book Publisher Pitch
A publisher pitched me their services for 'the serial killer's book.' I played along. I suggested smuggling payment out in a cheesecake. They said yes.
They were very flexible on payment terms. 📖
The LinkedIn DMs
Regularly gets messages from strangers: 'Hey, are you THE David Berkowitz?' followed by nervous backpedaling when they realize what they just asked.
Yes, I am THE David Berkowitz. The marketing one. Relax. 💬
Having 'The Talk' With My Kid
Every parent dreads having the talk. Mine was: 'So... there's another David Berkowitz, and he's... well... not great.'
Parenting milestone unlocked: Explaining why Googling Dad is complicated. 👨👦
The Dating Scene
First dates were interesting. 'So, David Berkowitz... should I be worried?'
Nothing says romance like 'I promise I'm not that one.' 💝
(It's always zero. Always.)
