About Sean
Sean McMillan has a well-deserved reputation as being respected as one of the most knowledgeable licensed brokers in Westside Los Angeles. With more than 1,000 successful transactions to his credit since 1985, he has helped countless buyers and sellers achieve their real estate goals. A third-generation native Angeleno raised on the Westside, he offers invaluable local expertise — including unique insights into its history, neighborhoods, schools, parks, and other amenities and resources — coupled with a deep understanding of market trends.
Sean counts his ability to strategize as one of his greatest strengths. A former chess master, he can see the transaction from both the buyer’s and seller’s perspectives, allowing him to anticipate and overcome potential obstacles for a smooth, stress-free experience on both sides of the negotiation table. For Sean, “It’s either win-win or no deal.” He builds long-standing relationships based on honesty, integrity, and empathy, and his word is gold: He never makes a promise he can’t keep.
Sean began developing his real estate skill set at a young age. Born into a family of professionals who defined West LA real estate, he grew up with a passion for the industry. His career has covered all aspects of the business, including home sales, title insurance, and mortgage brokering. This comprehensive background enables him to confidently guide his clients through a variety of transactions while ensuring they are informed and empowered to make the best possible decisions.
One of the best decisions Sean ever made was forming a partnership with Heyler’s co-director, Jae Wu. After working at a top firm together for several years, Sean and Jae realized their diverse talents and similar life philosophies made them an unstoppable team. They joined forces in 2005, and in 2011, they purchased Heyler Realty. Sean and Jae approach each transaction as a team, providing clients seamless concierge care and more than 60 years of LA real estate expertise.
In all aspects of his life and work, Sean leads with compassion and integrity. He has received multiple awards from the cities of Los Angeles and Santa Monica for his numerous civic and charitable efforts, which include being the co-creator and treasurer for the Westwood Neighborhood Greenway, the chair of West LA Homeless, and the founder of Santa Monica Chess Park.
