Rick Diaz

Rancho Cucamonga, California

For Rick Diaz, Southern California’s foothill communities are more than the markets he serves, they’re home. Having lived in the area for his entire life, Rick brings a personal connection to its neighborhoods and a longtime resident’s perspective to helping people find their place within them.

His real estate story began in 2000, working alongside family while completing his business degree at the University of La Verne. That foundation introduced him to the business from the ground up, combining classroom learning with the personal responsibility of helping clients buy and sell homes. He later attended the University of La Verne College of Law, broadening his education before building a business of his own.

In 2008, Rick founded his team Mainstreet Group. As a team leader, business owner, agent, and investor, he has experienced real estate from multiple perspectives, each shaping his hands on approach to service, negotiation, and leadership. Rick remains committed to helping both clients and agents move forward with the knowledge, resources, and support they need.

Based in Rancho Cucamonga, Rick serves buyers, sellers, and investors throughout the foothill communities and surrounding markets of Upland, Ontario, Claremont, La Verne, Fontana, Rialto, San Bernardino, Eastvale, Chino, and Montclair. His approach pairs deep local knowledge with personalized guidance and modern marketing. Whether helping someone purchase their dream home, market a longtime family property, or evaluate an investment, his goal remains the same: an exceptional experience tailored to the person behind the transaction.

Rick is excited to begin the next chapter as he and his team join Compass, bringing the same local knowledge, personal relationships, and commitment to their communities, now backed by the strength of Compass.
