I’m John C. Pak, a Certified Financial Planner™ and founder of Otium Advisory Group. My mission is to help time-starved professionals—those who barely have time for lunch—cut through the noise and finally feel confident about their financial future. With a clear, no-fluff approach to retirement readiness, I create simple, effective strategies designed to fit real life—not a textbook. I believe financial planning shouldn’t feel like a second job, so I focus on what matters most, eliminating the jargon and complexity that gets in the way. Aside from my life-long devotion to personal finance, my other passion point is teaching. I've been presenting retirement literacy courses at select Southern California Universities since 2014. I believe… - If you are open to the idea of prioritizing, organizing, and purging, you will save time and money. - If you change the way you see things, you will change the way you do things. - If you find someone to go along with you on your financial journey, you will have more success. Take advantage of the complimentary consultation. I look forward to sharing my vision of how we can get you to the finish line.
