A 20-year real estate veteran focusing on helping the individuals and families of Southern California navigate the real estate market. Whether buying or selling, trust experience. My expertise is residential real estate and multi-family investments.

With over 20 years of experience and more than 500 homes sold across Southern Sonoma and Marin Counties, Rick Warner is a seasoned expert known for his strategic, client-first approach to real estate. As the founder and team leader of The WE Group, Rick leads a powerhouse team where every member is an expert in their role—delivering a white-glove client experience rooted in precision, care, and results. Rick is a certified Probate and Trust Specialist with deep expertise in complex transactions, including divorce and asset dissolution. He is also a sought-after real estate coach, mentoring agents to build scalable and sustainable businesses. Rather than a traditional sales approach, Rick and his team take a consultative role—guiding clients through each step with clarity, honesty, and confidence. Their systems-driven process ensures that every listing stands out and every buyer is positioned to win. At the core of it all is one simple truth: no one out-negotiates The WE Group. In a world where hundreds of thousands of dollars can be on the line, Rick’s unmatched negotiating tactics often make the difference between a good deal and a mind-blowingly great one. Outside of real estate, Rick is a lifetime golfer, avid tennis player, and—just to keep things interesting—a marathon runner in his 50s. He’s also a proud dad of four, all now thriving adults.

I’m a residential real estate specialist serving the South Bay, Palos Verdes, Long Beach, and surrounding communities. I focus on guiding buyers and sellers with clear strategy, strong negotiation, and a step-by-step approach that removes uncertainty from the process. Whether you’re purchasing your first home or preparing to sell, my goal is simple: help you make confident, well-informed decisions that protect your investment and maximize your results.
