About
Welcome to The Grubb Co.
Let’s redefine your real estate experience together.
As a locally owned brokerage since 1967, The Grubb Company takes pride in being deeply rooted in our East Bay community. We've been setting the high bar for luxury real estate, and we cherish the relationships that we have built with our neighbors and clients.
Here's the thing: We may not be the biggest name in the game, but that's what makes us special. We are all about personalized service and genuine connections. When you choose us, you are not just another transaction; you become a part of our loyal clientele.
Our dedicated team of real estate professionals is passionate about our community and helping you achieve ultimate success. We are committed to understanding your unique objectives and guiding you through every step of the buying or selling process. Extraordinary is the standard at The Grubb Company.
You see, being a locally owned company means we have a deep understanding of our local market trends, the hidden gems, and the nuances of our neighborhoods. We are invested in the success and growth of our community, and we take pride in showcasing the beauty and potential of each property we represent.


Our History
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.
A Luxury Real Estate Firm in a Dynamic New Environment
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!
Innovation Through Technology
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 relationships that so often lead to optimal outcomes.
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 surpass all other brokerages in the area. We are the talk of the town!
Community Engagement The Heart of What We Do
The Grubb Company celebrates the rich diversity of cultures, ideas and backgrounds that make our East Bay communities thrive. Since the company was founded in 1967, we have continuously contributed to the institutions, causes and support services that are critical to the advancement, health and welfare of our community.
The East Bay is not just a place where we work. This is our home and we take care of it.
