A bit about me — I hail from Central America but have called the San Francisco Bay Area home since I was a boy. I'm a proud UC Berkeley alumnus with a degree in Sociology. My pre-real estate journey was equally diverse and enriching, spanning from financial consulting to advertising, where I honed my skills in communication and strategy.

So, if you're looking for a real estate experience that's as enjoyable as a San Francisco sourdough — distinctive, satisfying, and uniquely Bay Area — I'm your broker. Let's embark on this journey together, with a sprinkle of humor and a lot of expertise.
