I'm Javier Brown, a commercial real estate agent in Ontario, CA with MGR Real Estate. I've been licensed since 2006 and have spent more than 20 years at MGR, after 15 years in sales at Cal Spas. Spanish is my first language, so I can work with you in English or Spanish, and I usually reply within minutes. I help clients buy, sell and lease industrial buildings, truck yards, land, retail and NNN investments across the Inland Empire.
