"Mark Rosen, together with the Rosen Realty Group team, is the most experienced real estate brokerage team in San Francisco. RRG took Mozilla from one location in Mountain View to 12 spaces around the world."
Jim CookChief Financial Officer, Mozilla Corporation
"In real numbers, Mark saved us over $200K a year; that gave us the ability to thrive as a company and to reinvest in our staff and clients. I can't imagine finding a broker anywhere that could do nearly as well."
"The thing that really stands out about Mark Rosen and his team is that they just have a unique way of anticipating and knowing what we need with our real estate space. I don't know how they do it. Maybe it's because Mark has a tenant-side-only practice, and he knows exactly what individual tenants need."
"We have worked with Rosen Realty for 17 years, and would not consider working with anyone else. Mark always surpasses our expectations. He has deep market knowledge, and that saves us time and money. He asks the right questions, and he is a great negotiator."
