Few Brokers have proven they can deliver sustained business in tough times. Fewer have a track record of 95% referral business. Even fewer are servant leaders who demonstrate an ability to help others grow their business and experience personal growth by drawing on first-hand experiences from the front lines.

Sin-Yi Lambertson is one of the very few.

Sin-Yi began her career in early 1980 as a sales associate for Realty World in Monrovia for 7 months & Ken Turner Real Estate through 1997. There she learned the basics of real estate and a faith in the only One who loves unconditionally & is trustworthy. It is at ERA and in owning her own company she learned the important lessons about discernment & practical application of wisdom in a constantly changing world.  Sin-Yi developed skills as a Senior Real Estate Specialist and rose to rank in the top 1% of United States in production in 2012 and a consistent awards winner for her work in real estate and in serving her community.  Sin-Yi’s most cherished award is the Humanitarian Award from Glendora in 2004.
