In this episode of Chu on This!, Dr. Katie W. Chu sits down with optometrist Dr. John Larcebal for a deeply reflective conversation about purpose, perspective, and what it truly means to live a meaningful life.

Dr. Larcebal shares his journey from building and running multiple successful optometry practices to stepping into semi retirement, where he now dedicates much of his time to international humanitarian eye care missions. Through his work with VOSH, he has served communities around the world, gaining a profound perspective on need, adaptation, and gratitude.

One of the most powerful insights from his experiences comes from working with children in underserved regions, where the prevalence of vision issues is significantly higher than in the United States. Yet despite having fewer resources, these communities often demonstrate deep joy, connection, and contentment.

The conversation expands into personal values, including integrity, honesty, family, and the responsibility that comes with parenthood. Dr. Larcebal reflects on how growing up on a farm shaped his discipline and work ethic, while also reinforcing the importance of keeping one’s word and living with consistency.

Katie shares her own reflections on legacy, purpose, and creating spaces where people feel safe to share their stories. Together, they explore the idea that success is not defined solely by professional achievement, but by the impact we leave on others.

This episode is a powerful reminder that perspective shapes everything, and that a meaningful life is built not through accumulation, but through connection, service, and intentional living.

Perspective changes everything Exposure to different environments and communities can completely reshape how we define success, happiness, and fulfillment.

Integrity and honesty are foundational values From handshake agreements to modern leadership, keeping your word and living with honesty remains essential in both personal and professional life.

Legacy is built through impact, not just achievement True success extends beyond career milestones. It is reflected in how we serve others, how we show up, and the difference we make in people’s lives.

“Having all these material things doesn’t always make us the luckier ones.”

“Back then, your word and your handshake… that was the contract.”

“It’s not just about what you achieve, it’s about the impact you leave behind.”

In this episode of Chu on This!, Dr. Katie W. Chu sits down with optometrist Dr. Arash Sadeghian for a powerful and deeply personal conversation about purpose, sacrifice, identity, and the defining moments that shape our lives.

Recorded during a break at the California Optometric Association House of Delegates, this episode moves seamlessly between lighthearted reflections and profound life insights.

Dr. Sadeghian shares his journey as a private practice optometrist of more than 20 years, reflecting on the realities of growing a practice, mentoring emerging doctors, and continuously evolving as both a clinician and a leader.

The conversation takes a powerful turn when he shares a pivotal story from his early life. He was nearly recruited by the FBI, a path that seemed to disappear as quickly as it appeared. Years later, while in optometry school, he diagnosed a life threatening condition in his own mother and ultimately helped save her life.

That moment reframed everything.

What once felt like a missed opportunity revealed itself as something far more meaningful. A redirection toward purpose.

Together, Katie and Arash explore the balance between career and family, the sacrifices required in healthcare, and the evolving nature of leadership identity. They reflect on the weight of responsibility, the importance of presence, and the small, meaningful moments that ground us in what truly matters.

From cultural roots and childhood memories to professional growth and legacy, this episode is a reminder that purpose is often only clear in hindsight, and that the path you are on may be exactly where you are meant to be.

Purpose often reveals itself through hindsight What may feel like missed opportunities can actually be redirections. Dr. Sadeghian’s journey shows how life aligns in ways we often only understand later.

Sacrifice is part of building something meaningful Balancing career and family, especially in healthcare, comes with trade offs. Meaning is found in how we navigate those sacrifices with intention.

Growth requires evolving your identity Leadership is not static. It requires reflection, feedback, and a willingness to adapt how you show up for your team, your patients, and your life.

“Everything happened for a purpose, for a reason… I couldn’t even imagine a different path.”

“There’s things you need to get done… but at the same time, it’s about providing great care for our patients.”

“At that moment, I realized this is why I’m here. This is why I chose this profession.”

In this episode of Chu on This!, Dr. Katie W. Chu sits down with optometrist Dr. Vin Dang for a thoughtful and wide ranging conversation about resilience, identity, and the experiences that shape the paths we choose.

Dr. Dang shares his remarkable journey from being born in Paris to immigrant parents of Chinese Vietnamese heritage, to eventually building a career in the United States as an optometrist. Along the way, he reflects on how his parents’ sacrifices shaped his work ethic and sense of purpose, and how unexpected opportunities helped guide him toward the profession he loves today.

The conversation moves beyond career milestones into deeper personal territory. Katie and Vin explore therapy, emotional awareness, empathy, and the lifelong process of unlearning habits and beliefs that quietly shape our behavior.

Dr. Dang speaks candidly about the role therapy played in helping him recognize the difference between criticism of an action and criticism of the self. That distinction, along with learning not to take things personally, became a turning point in his personal growth.

Together, Katie and Vin also discuss the importance of having a supportive “village” of people who keep us grounded and help us see ourselves more clearly. Whether through family, friendships, mentorship, or therapy, growth rarely happens in isolation.

Blending humor, vulnerability, and wisdom, this episode highlights how life’s defining moments, both joyful and painful, can become powerful catalysts for transformation.

Growth often requires unlearning old patterns Therapy and self reflection can reveal the difference between criticism of who we are and feedback about what we do. Learning that distinction opens the door to empathy and emotional maturity.

Immigrant stories often fuel resilience and purpose Watching his parents leave a comfortable life in France to build opportunity in the United States deeply shaped Dr. Dang’s drive and commitment to honoring their sacrifices.

We all need a village to grow Family, friends, mentors, and therapists help us stay grounded and see ourselves more clearly. Personal growth rarely happens alone.

“It’s learning the difference between someone criticizing you and someone criticizing an action. Those are two very different things.”

“My wife always reminds me: it’s not always about you. Sometimes it’s about how your actions affect other people.”

“Seeing my parents sacrifice their comfortable life so we could have opportunity here shaped who I am today.”
