About Hill & Co. Real Estate

Since its founding, Hill & Co. has been one of the premier San Francisco real estate brokerages. Few have focused their attention on this city as we have. Our company offers all the attributes of a boutique brokerage, while at the same time providing cutting-edge technologies, comprehensive networking channels and global marketing opportunities.

There is no better testimony than from our valued clients who choose to return, time and again, to Hill & Co. More than 72% of our business comes from the friends and families of these clients. Such loyalty means we enjoy the unique distinction of having worked with multiple generations of San Francisco families and some of the city's finest properties.

When representing sellers, we understand the importance of heightened exposure, both locally and around the world. Our San Francisco real estate agents are well-known and respected within the local real estate community. We have access to a large national and international network through our affiliation with "Who’s Who in Luxury Real Estate" – an organization comprised of more than 1,500 premier luxury real estate brokerages worldwide.

When representing buyers, we know the importance of taking a strategic approach to the purchase of a home. We know how to position our buyers so that they can make an offer that resonates with sellers - one that stands apart from the rest.

We were founded in San Francisco by Joseph Costello, a native San Franciscan who received his J.D. degree from the University of San Francisco School of Law. Today we remain proudly independently owned, home to nearly 100 brokers and agents located in three sales offices throughout the City.

In addition, the company owns and operates a property management group, with offices in San Francisco and Marin.
