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 President of West LA Homeless - a nonprofit he created to connect unhoused people with service, and the founder of Santa Monica Chess Park. He serves as homeless committee chair on the Westside Neighborhood Council.

Sean was named one of Triple's Best Realtors in Los Angeles. Sean, Jae and Heyler Realty received the LA Works Small Business Big Impact Award and the Side Community Impact Award.

He’s happily married to Jill McMillan, one of the genius chefs behind Mac & Ivy, and he’s a proud father of four. When he’s not spending time with his family or volunteering, Sean enjoys gardening, hiking, biking, and all sorts of ocean-related activities.

What My Clients Say

Heyler Realty helped us sell our first home, and we could not be happier with the outcome! Sean helped us effectively time the market, market, and stage our home. Throughout the process, Sean was a pleasure to work with. He promptly and clearly communicated, answered all of our questions, and made the process incredibly easy for us. Cannot recommend Heyler Realty and Sean enough.

We’ve been working with Sean and Jae for over 10 years as our family has grown and our real estate needs have evolved. Having a realtor who is so experienced in the LA market is a huge advantage when it comes to conveying earnest interest and credibility to sellers who have multiple offers on the table.

I have used Team Heyler for both my property purchases and the sale of one of those properties, and they never disappoint. They care about getting the best results for their client and will go to the mat for your needs. They ooze care and consideration, but don't be fooled by their kindness! They are tough and have decades of experience!

What My Clients Say

My agent, Jae, and her partner Sean went above and beyond for my first home purchase. It was evident that they have been working with other agents and buyers in the West LA area for more than 2 decades. Throughout the entire process, from going to open houses to the end of escrow, Jae was incredibly professional and responded to all my questions thoroughly and timely manner. Buying my first home was very...

What My Clients Say

You can begin studying chess today. Regardless of how much time you spend, you will never become the world chess champion. Sean didn't become the best, most knowledgeable agent by taking up real estate later in life. Like every world chess champion, Sean began his profession in childhood. He was born into a West Los Angeles real estate family. Sean doesn't have to guess the best move or try to figure out...

What My Clients Say

We entrusted the Heyler team to sell a Rancho Park property that had been in the family for over 60 years. Sean, Jae, and the entire Heyler office made our transaction as comfortable and financially lucrative as possible. Their knowledge of both the local real estate market and the larger financial atmosphere was exceptional. The foundation of any large transaction like this has to be ‘trust’. We trusted...

Jae was incredibly skilled, had detailed and smart advice for every single step of our sale. Could not recommend her more highly, not sure we would have ended up purchasing without her.

— Laura Waters

What My Clients Say

We found Jae online and little did we know how great she would be in real life. From start to finish, she was extremely responsive, hardworking and dedicated to the cause of helping us find our dream home in LA. She on multiple occasions made last minute weekend showing happen for us. She helped us negotiate multiple occasions with a few different counterparties. Now that we have purchased a home, she is...

What My Clients Say

It was my privilege to have Sean Mcmillan as my real estate agent/broker. I was a nervous, first time seller and Sean guided me through the entire sales process. He quieted my anxieties, explained perplexing details, and solved problems. I felt truly blessed to have Sean working for and with me.

The crew at Heyler is fantastic! You can put your full confidence in them. Heyler will really take care of you, fight for you, and treat you like family. They're making sales, and, more importantly, making friends. They know what's going on in the neighborhood, and they know the community.

What My Clients Say

Jae and Sean helped us sell our late mother's house. We live on the East Coast and they were able to provide us with services referrals that were excellent. They helped guide us through every step through to completion of the sale. It was an odd time in the market and though a couple of offers fell through, we managed to work through it all to a satisfactory conclusion. They make and have a great team an...

What My Clients Say

5 stars! Couldn't be happier with our choice to work with Sean and Jae. They were very collaborative, truly listened to what we wanted and made it a point to go the extra mile to achieve our goals. They also provided timely and pertinent advice in a rocky real estate market and made a ton of good vendor referrals. We'd interviewed a few folks before a colleague recommended that we meet Sean and Jae and w...

My overall experience was OUTSTANDING! Jae Wu is exception…she is competent, responsible, and personable. Jae and the group were wonderful guides leading me through the process. They made it easy for me and I felt my well being was important to them. I highly recommend Jae and Sean.

— Phyllis G.

What My Clients Say

Having worked with Sean on multiple real estate transactions over the course of 20 years, we would not consider buying or selling property anywhere in Los Angeles without Sean’s help and guidance. Not only does he have a deep sense of the real estate market, but his commitment to the community translates into a personal mission to pair people with not just a house, but a home.

— Rachel I.

What My Clients Say

First and foremost we feel blessed to have had Sean handle our precious house sale after 20 years of blood, sweat equity and a multitude of memories. He negotiated a very fair proposal and still invested his personal time in making sure we were ready as well as our home for market. Sean is truly a unique business person (Realtor®/owner); he is very capable and helped greatly when the negotiation stalled....

What My Clients Say

I had the good fortune of working with Heyler Realty’s Sean McMillan selling two properties to buy one. He instinctively knew exactly what I wanted to do and in what time frame in order to buy our fabulous condo on the Westside. Timing wasn’t exactly right selling one of the properties, but Sean worked his magic with the escrow company to make it a smooth and easy transition. I didn’t lose any sleep over...

— Judy E.

What My Clients Say

Working with Sean McMillan and Heyler was a pleasurable experience in many ways. Sean was transparent throughout what was an emotional experience handling the sale of my mother’s home of 60 years. Sean kept my family abreast of the various stages of the process from listing the property to closing escrow. I never felt pressured to make any decision, and Sean would explain things in great detail. I woul...

What My Clients Say

I am delighted to write a reference letter for Sean McMillan. Indeed, in the summer of 2020, when he served as my Realtor® in selling my Santa Monica townhouse, I was so satisfied with his service that I offered to write one if he should ever have a need. Mr. McMillan is simply the best Realtor® I have ever encountered in over thirty years of buying and selling multiple residential properties in L.A. Se...

What My Clients Say

Working with Sean and his team at Heyler was a wonderful experience. I knew immediately that I could trust in Sean for everything. He was professional, yet gentle and kind. Honest, yet tough to make sure I wasn’t being taken advantage of and traditional and protective of me. Something like buying your first home can be scary, but Sean walked me through every step of the way and I love my home and will al...

What My Clients Say

The group at Heyler Realty is beyond amazing. My family had twice the love this year from Jae and Sean at Heyler this year. We bought one of the properties they had for sale and helped me find my forever home. I have know Sean and Jae for many years and have always respected their work ethics, dedication to their clients, to their community and of course their families. I always knew I would find Sean on...

— Amy R.

What My Clients Say

Sean and Jae are incomparable. Trust me – you don’t want to work with anyone else. They helped us sell our condo and buy a single family home while navigating a global pandemic with grace, compassion and unflagging professionalism. We were not easy clients, I’ll admit. Anxious, fiscally conservative, prone to bouts of dramatic tears – what can we say? Buying a home is emotionally challenging, and selling...
