About Marc Gross

My values - Integrity, honesty & transparency

I believe the phone should never go unanswered and as your trusted real estate professional, I take great pride in the fact that my clients can always reach me, no matter what day or time. My commitment to white glove, concierge service comes from a lifetime of service to the public, both professionally and personally.

With nearly a decade in the real estate industry, I have extensive knowledge of the Los Angeles market and the unique and diverse neighborhoods that make up this great city. I am vigilant in keeping up with the rapidly changing market, from home prices, to lending products, to legislative action, analyzing how these factors may affect the goals of both buyers and sellers.

My career in real estate began with a job apprenticing with a top real estate appraiser. This position provided me with the opportunity to really grasp the needs of the diverse communities unique to L.A., so no matter what your requirements or location, I can provide information you can trust.

What makes me unique is the level of service I provide to my clients and how I deliver it. My extensive travels and experiences, immersing myself in different cultures, has given me a global perspective about what’s important to different people and how to best service their needs. That service continues far after the sale of a home. It is my goal to be your realtor for life, a trusted advisor and a go-to for information, advice or anything related to the real estate market.
