The Grubb Company

Welcome to The Grubb Company

We are the leading residential real estate company in the East Bay, and have been since 1967. Get to know us. You can count on our talented team of 85 agents and 15 professional full-time staff for all your real estate needs.



When our founder, Donald Grubb Sr., opened our doors many years ago, he envisioned a locally owned company with a broad footprint. His vision has become our legacy – and our trajectory.

The Grubb Company isn’t corporate. We don’t mine your data or sell your stats. We don’t have franchises, nor are we a tech company. We are simply the biggest and the best at what we do in our community.


While The Grubb Company has grown significantly, our principals, D.J. Grubb, John Karnay, and Robert Belzer, Esq., manage the business with the same sense of excitement as when they started. Only a boutique firm can maintain our level of innovation and responsiveness. Our team is dedicated to helping you find the luxury real estate of your dreams. We have years of experience and are highly aware of all housing market trends. Our goal is to make the home selection process as easy as possible, so you will be able to find a place in an efficient manner. After consulting with our agents, we will begin to find homes that will not only fit into your budget but will also meet the criteria you are looking for. Our negotiating skills will help you attain luxury real estate at the best price possible. Contact us today to begin your journey to finding a home!



The Grubb Company is all about reach, influence, and confidence. In recent years the dynamics of selling residential real estate have changed dramatically, and we could not be more prepared. Our reach is worldwide. Virtual connection with others is a fact of life. So the real task is harnessing people’s attention, and that’s where we excel.

By continually honing our message and our targeted media, from print to video, we mix old and new to keep the real estate sales experience interesting. At the same time, we rely on the depth and breadth of our real estate real-life relationships that so often lead to optimal outcomes.

At GRUBBCO.COM, you’ll find the most comprehensive portfolio of East Bay residential properties anywhere. Buyers from over 200 countries worldwide access our listings.

Clients also stay connected with us through our campaigns on Facebook, Instagram, Twitter, and Pinterest. It’s no surprise that our social media visibility and engagement surpasses all other brokerages in the area. We are the talk of the town!
