Casey is a member of the Society of Industrial and Office Realtors and the National Association of Realtors. His clients include Bank of America, County Bank, Swiss Bank, Bank of Nova Scotia, MCI Telecommunications, Intuit, Posit Sciences and Quokka Sports.

Prior to Cresa Partners, which he joined in 2005, Casey spent 10 years running his own business, Triton Commercial Real Estate, a San Francisco based advisory and brokerage company. Prior to that, he worked at Colliers for 14 years. Casey tells GlobeSt.com that he decided to shut down his own business after a decade because it was under capitalized.

"We had a fabulous time during the dot-com days as we were passed around from client to client but I could never find seasoned people I wanted to work with, and without a critical mass of three experienced brokers its very hard to turn the corner in the brokerage business," he says. "I was trying to finance out of my own pocket the tools that my larger competitors provided brokers because I didn't want to compromise on the caliber of people I hired. I trained some young guys that went on to do well, but it was just too much work.

"We did a very good job for clients and the quality of work was very high, but I frankly got tired. It was a great experience and I'm very glad I did it, but I'm very excited about being here at Colliers again; I haven't been so enthused in years."

As for his short tenure at Cresa, Casey says he originally wanted to go there to help the firm ramp up its San Francisco operation. Shortly thereafter, old friends from Colliers began calling him, suggesting he return to Colliers. "I got like nine calls from brokers over there, and I started listening to the siren song," he says.

Coming with Casey to Colliers is Bill Flannery, an associate broker who worked with Casey at Cresa Partners. Like Casey, Flannery specializes in tenant representation. Cresa's San Francisco-based EVP Stephen Polito also did not return a phone call seeking comment.
