About Joshua

In 2023, I'd just been hit by tech layoffs. A few months later, a routine checkup revealed pre-cancerous growths in my colon. I felt thrown overboard, lost at sea, barely treading water with no bearing. It took nearly a year of soul-searching, awkward coffee chats, and random gigs before I found the courage to reapply for MBA programs. I'm glad I did. The first time around, I'd forced my narrative into traditional career goals, guessing at what adcoms wanted to hear. This time, I embraced the mess instead of editing it out and spoke candidly about the changes I wanted to see in the world, with an MBA as the staging ground for what came next. That’s where my passion for "longevity," and adjacently, self-improvement, was born — out of a long struggle to find meaning and overcome my health scare. Now, as a 2nd year MBA candidate at Columbia, I'm exploring technologies that help people live longer, healthier lives — first as an early-stage investor, before delving into my own entrepreneurial ideas.

Why do I coach?

My own MBA journey wouldn't have been possible without the countless people who let me talk in circles until I found my own thread. People who believed in a version of my story before I could see it myself. I coach because I want to be that person for someone else. But beyond gratitude, I coach because I genuinely love uncovering and crafting a powerful story. I believe everyone has a story worth telling. Most people just haven't been given the space, or the right questions, to find it. I enjoy finding the small details that make an experience specific instead of generic, cutting the parts that sound impressive but say nothing, and finding the thread that ties a scattered set of experiences into a single, honest narrative. That's the real lesson my MBA experience has taught me: it isn't a performance, it's a story. And the version worth telling is usually the one you're most afraid to write down. Helping someone else find theirs is the best part of this work.
