What Our Clients Say "I consider Mark my secret weapon in the war against over paying rent - an entrepreneur's dream! Honestly, I cannot say enough good things about Mark and his ability to sniff out a deal. Through two companies now, he has consistently found me the best real-estate deals on the planet. One time we paid $3,333 a month for 20,000 sq/ ft of A+ office space on California and Kearny (cost BofA something like $30k a month). The guy is a bloodhound for the value. On the downside, Mark is very personable, operates with very high integrity, does not over-sell, and is a great triathlete :) Chris Churchill CEO at Optimate Networks (formerly AMPP Media) Former CEO, Founder at Fathom Online "Our firm hired Mark to help us find new office space after 30 years in the same location. Mark provided excellent service and advice that exceeded our expectations. Mark is organized, detail oriented and most importantly is able to guide and advise on the 'big picture'. I would recommend Mark and his company to anyone looking for a real estate broker." Dave Cuneo Partner at Calegari & Morris, Accountants "Mark and his wife Anna work together and are both attorneys that only represent tenants giving us not only the highest level of expertise possible but zero conflicts. Mark and Anna have saved my bacon a number of times based on their extensive relationships in the San Francisco market. I always refer to Rosen Realty as real estate magicians!" Chaz Berman Chairman of the Board & Chief Executive Officer at UCB Network, Inc formally Bond Rewards Former COO at MyPoints Inc. "Mark is outstanding and a true professional. He worked just as hard for us when we were broke at Xoom.com as when we were at NBCi and did one of the largest lease deals in SF history. Mark saved us money, time and most importantly, got us a screaming deal." Chris Kitze Entrepreneur Former Chairman at Wine.com Former CEO at NBCi.com Former Chairman at Xoom.com "Mark has handled my firm's leasing for more 16 years. His understanding of the market is prophetic, his integrity is unquestionable, and he is always fun to work with. I give him my highest recommendation as a business partner."
