Hear testimonials from people who have worked with John Jack as a mentee, contemporary, or confidante
Lavin Ma, Mathematics-Computer Science Student at University of California, San Diego
“Beginning a mentorship with Dr. John Jack (or Dr. J) was the absolute biggest step I took for my future. I hoped for guidance as a freshman just entering UCSD. And, as a mentor he supported my undergraduate navigation, introducing me to industry colleagues and prestigious research programs.
Dr. J helped bring me out of my comfort zone of the classroom into a research lab at the UCSD Halicioglu Institute of Data Science where I ended up discovering a desire to further my studies at graduate school. It’s easy getting lost or stuck trying to figure everything out on your own, but Dr. J always kept me grounded in my goals while keeping our meetings equally lighthearted and fun. Personal growth doesn’t have to be the daunting task it’s often made out to be; it is a challenging but rewarding journey that reinvigorates your fire.”

“I’ve had the privilege of knowing John for around five years, and in that time he has been nothing short of an incredible cheerleader, mentor, and friend.
While writing this review, I realized that what really sets him apart is his genuine passion for helping others see the world in a more positive and hopeful light. From the very start of our relationship, he demonstrated a remarkable ability to see the glass half-full. Even when life got hectic or the world felt heavy, he always found time to check in, offer a fresh perspective, and ensure that I never felt like my struggles were slipping through the cracks.
What makes him such an effective coach is that he genuinely lives what he teaches. He encourages people to think outside the box and not get bogged down by the day-to-day grind. He has a way of making you feel seen and heard, and he uses his own time and energy to make sure that you’re doing okay and thriving.
In short, if you’re looking for a coach who truly cares and has the ability to inspire and uplift, John is absolutely that person.”
Subbu Hariharan, Data Science and Growth Leader @ Intuit

“I have had the good fortune of meeting John Jack and getting to know him as a close friend and confidante. He is compassionate, self-aware, funny, highly intelligent, and an incredibly diligent hard-worker.
John cares deeply for others, noting their strengths and supporting their growth points with the same determined dedication that he puts forth toward his own growth.
His ability to take what he has learned to help himself and use it to support others in their journeys of self-development is remarkable. My life is enriched by John’s presence and I know that anyone who turns to him for guidance will find that their life is enriched by him as well.”
