Uwe has been in the real estate business for over two decades and has purchased, renovated, rented, and sold his own real estate portfolio throughout the West Coast. This experience best serves his homebuyers, investors, sellers, and families before, during, and long after the sale.

Prior to becoming a real estate broker, Uwe has been a VP of Application Services in Silicon Valley and developed the acumen and understanding of complex sales processes. His business accolades include an extensive accounting and management consulting background, which also put him in a position to serve his clients from a holistic point of view.

Uwe has since developed a flourishing career and remarkable reputation amongst his clients and within the real estate industry. Uwe has a tenacious work ethic and possesses both the emotional intelligence and the professional poise that is critical for being successful.

He is in constant communication with his clients as they go through the process and continually goes above and beyond the call of duty.

Uwe fully embraces the rising prevalence of technology in this industry and recognizes how it helps his clients to assess the market in real-time.

His technological savviness, attentiveness to client needs, over two decades of extensive local market expertise and passion for marketing give him an edge and guarantees optimal client results.

Plus, having lived in four different countries and speaking five different languages, allows him to fully understand the challenges that our multi-cultural clientele encounter.
