To Dennis Hsii, every single one of his clients is family, and he treats each one to the same reassuring level of care, advice, and guidance. That, along with putting his clients first, goes a long way toward Dennis’ goal of delivering concierge service and excellent outcomes.

Before launching his real estate career, Dennis was a management consultant for several major U.S. companies, where he developed strategies and implemented IT systems solutions. After becoming a real estate agent, Dennis joined forces with Vivian Yoon to create Highland Premiere, the product of their mutual philosophies, goals, and work ethics.

Real estate represents everything Dennis is passionate about: home, architecture, art, negotiations, and investments. He began investing in Silicon Beach real estate in his 20s, and his experience with purchases, sales, and investments make him indispensable to clients looking to build their own portfolios. Dennis also has expertise in negotiations and conflict management. He touches every price point and property type, and uses his data-driven background to help his clients make well-informed decisions. His energy and humor are just added bonuses that help make the process enjoyable.

Vivian Yoon treats every client like family, serving them with the utmost integrity and honesty. Those values define Highland Premiere, the firm she co-founded in 2014, but Vivian has been basing her innovative concierge service on them since 2007. Since then, she has had extensive experience in luxury residential sales, new construction, and relocation in Los Angeles, Orange County, and the Bay Area. Though she specializes in assisting first-time buyers, seasoned investors, developers, and higher-net-worth young professionals from all corners of the world, Vivian values the opportunity to share her expertise with all clients. Seeing them happy pushes her to work even more diligently on their behalf.

Born and raised in Los Angeles by a mother who is a lighting architect and interior designer, Vivian has been exposed to beautiful homes since she was a child. Her interest in real estate sales was piqued when she worked in the luxury properties division at Christie’s Auction House, and she decided then that brokering them would be her next career. Now, Vivian uses her local knowledge and vast network to give her clients a competitive edge. She is also a seasoned flipper and builder with a comprehensive understanding of the construction industry.

Vivian holds a bachelor’s degree in political science and art history from U.C. Davis and an MBA from the University of Southern California’s Marshall School of Business (USC). She is fluent in Korean, and in her spare time, Vivian helps young women break business barriers through several USC mentorship programs. She also enjoys painting, Pilates, and traveling.
