About Our Team

Since its inception in 1984, RRG has been a boutique tenant-only brokerage firm. We were the first tenant brokerage in the San Francisco Bay Area, and we remain the longest-standing, independent tenant representation firm to this day. We are very proud of having withstood three decade’s worth of leasing and economic cycles, with a decent-sized earthquake thrown in for good measure, yet our business continues to thrive. We have fun every day because we love what we do.

Tenant representation is in our DNA. We chose this niche because of our legal backgrounds, knowing full well the issues that arise from conflicts of interest and dual representation. Our singleness of purpose achieves the very best outcomes for our clients.

Our tenant-only reach broadened in 1994 when RRG partnered with ITRA Global (the International Tenant Representative Alliance), the longest standing pure tenant rep organization in the world. For many years, RRG served as a leading member of this organization. In the late 1990’s, RRG expanded its clientele to include tech firms. RRG was awarded the 1999 Biggest Deal of the Year by the San Francisco Business Times for its representation of NBCi at 225 Bush Street (250,000 rsf on 10 floors for 10 years).
