From Hong Kong to New York to Lamorinda, Judy Sin’s journey is proof that reinvention isn’t about changing directions — it’s about growing with purpose. Ranked among the Top 1.5% Realtors nationwide by RealTrends 2024 and recognized as a Compass Top Producer, Judy has quietly built one of the most trusted names in East Bay real estate, combining global perspective, marketing finesse, and genuine care for her clients.

From Hong Kong to New York: A Rebel at Heart

Born and raised in Hong Kong, Judy attended the same all-girls Christian school from kindergarten through high school. This environment shaped her discipline and independence.

“I’ve always been a rebel at heart. I’ve never been afraid to start over or do things differently.”

After earning her degree, Judy moved to Chicago for graduate studies in International Public Administration. Her studies took her to France, Mexico, and Brazil. There, she worked with refugee communities and learned that leadership starts with empathy.

The United Nations Chapter

When Judy landed an interview at the United Nations in New York, she was asked if she had a backup plan if she wasn’t selected.

“No, I don’t. Because I don’t plan to fail.”

That answer earned her the position and became a guiding principle throughout her life.

Building a Career in New York City

During her decade in New York, Judy founded a successful conference production firm. She created global business summits for top U.S. pharmaceutical companies like the FDA, Pfizer, Merck, and Johnson & Johnson.

“My job was to design events that attracted the most prominent leaders and decision-makers. It taught me how to understand what truly captures attention — a skill that now helps me spotlight every home I represent.”

Her mastery in content strategy and storytelling would later become the foundation of her success in real estate.

The Leap to California

After years in Manhattan and Long Island, Judy and her husband decided to move closer to family in California. They arrived in 2020 — just as the world shut down.

Judy laughs when recalling those early months:

“We moved across the country without knowing anyone. My kids couldn’t even see people’s faces because of masks — so we bought ten chickens. They became our first friends.”

That humor and adaptability became the cornerstone of her next chapter.

Reinventing Success in Real Estate

While the world slowed, Judy found her voice online. Encouraged by Compass’s marketing team, she began sharing her story on social media — not to sell, but to connect. Her authenticity resonated instantly.

Within her first year as a solo agent, she sold over $20 million in homes. By 2024, she surpassed $60 million in career sales, earning her a place among America’s Best Real Estate Professionals.

“My biggest accomplishment isn’t the sales volume. It’s that people entrusted me with their biggest life decisions. That trust means everything.”

Marketing with Meaning

Judy’s former life as a conference producer gave her an edge few Realtors possess — the ability to craft strategy and narrative around every listing.

“Each Lamorinda property is unique. My role is to find its voice — and present it so the right buyer can see its full potential.”

Her listings are known for magazine-ready presentation, thoughtful storytelling, and targeted exposure across English, Cantonese, and Mandarin audiences. It’s an approach that consistently draws strong offers and record results.

Looking Ahead

Today, Judy continues to serve clients across Lafayette, Moraga, Orinda, and Walnut Creek. She blends deep local expertise with a global mindset. Her blog, Triumph Tales, documents real-life stories of persistence, creativity, and heart behind every sale.

“Every move I’ve made — from Hong Kong to New York to Lamorinda — taught me that growth is never about luck; it’s about showing up. That’s what I bring to every client — clarity, care, and commitment.”
