Licensed since 2005 and elevated to the status of Broker in 2010, I've personally navigated over two hundred real estate transactions. My expertise lies in both new home sales and luxury residential real estate, positioning me as a proven authority in the field.

Having engaged with thousands of individuals throughout my career, I've gained valuable insights into what truly matters to them when finding a place to call home.

In a dynamic industry that demands exceptional marketing and selling skills, I understand the necessity of quick adaptation, pushing beyond conventional methods, and consistently evolving my approach to business.

My passion extends beyond real estate into the realms of design, inspired living, and the vibrant city of San Diego! Daily, I encounter innovative, stylish, and environmentally conscious designs from around the globe aimed at enhancing our quality of life. These elements continually inspire and shape my perspective, from chic interiors and breathtaking architecture to unique home additions and cutting-edge smart home features. Stay tuned for new trends as I share them through weekly posts!

My approach to business is not only driven by a passion for excellence but also fueled by creativity, boundless energy, and genuine enthusiasm for each project I undertake.



Specializing in vacant land and real estate development, my journey in the industry began in 1987. Over the years, I have immersed myself in various aspects of residential and commercial real estate development.

Upon obtaining my real estate license in 1989, I dedicated four years to working closely with mentors, delving into the intricacies of the real estate development business. This invaluable time allowed me to fine-tune my skills, leading to opportunities across diverse projects such as residential development, multi-family development, urban rehabilitation, and light commercial real estate.

These varied experiences have shaped a comprehensive knowledge base and cultivated an analytical, solution-focused approach to every venture.

Fast forward to 2024, and I take pride in being at the forefront of my field, conducting business in Southern California Counties with a primary focus on land development, commercial real estate, and investment.
