Rosen Realty Group

Mark C. Rosen, President:

Since 1984, Mark C. Rosen, president and founder of San Francisco-based Rosen Realty Group, has been representing office tenants exclusively. At that time, he was one of only a few brokers in the Bay Area to do so.  More than twenty-five years later, Mark continues to bring to the negotiating table his extensive knowledge of the local office leasing market, along with his high standards of integrity and honesty, to get the best possible deal for his clients. As a result, Rosen Realty Group is widely recognized by its clients, and within the brokerage and landlord communities, as fair and tough negotiators who are successful at closing deals. Mark’s legal degree and study of real estate law adds an important dimension to his expertise in tenant representation.

Rosen Realty Group typifies the best of the San Francisco Bay Area: a local, family run business that is recognized as the best at what they do -- working for the tenant with integrity. It's no surprise that the majority of the company’s business is from existing clients and referrals. 

In a gala celebration, Mark was awarded the San Francisco Business Times 1999 “Deal of the Year” for his work in representing NBCi. Some of his other clients include Wine.com, Modem Media, ABC-TV, KGO-TV, Wild Planet Toys, MBIA, Robert W. Baird & Co. 

Rosen Realty Group has been a member of ITRA since 1995, and Mark currently serves on the Membership Committee.  Through its ITRA partners, Rosen Realty Group provides tenant representation for its clients in cities throughout the US and Europe. 

Mark and his wife, Anna, are raising their two sons, Spencer and Jordan, here in San Francisco.  The entire family has the distinction of being the only one in the country with its own athletic team, Rosen Realty Racing.  Together they compete in triathlons, road and mountain bike races, slalom ski races, and group swims from Alcatraz.   Mark also puts on the annual SF Bay 10K Swim from the Golden Gate Bridge to the Bay Bridge. 

Mark is a fourth-generation San Franciscan who graduated from Lowell High, has a dual B.A. from San Jose State in business and political science, and a J.D. from San Francisco Law School.  He is also a proud 20+ year member of the Olympic Club and currently serves on its Membership Committee.
