In five years at Crosby, Heafey, Roach & May, Mr. Knudsen spent the majority of his time in the Employment and Intellectual Property litigation practice groups. During that time, Mr. Knudsen co-authored articles involving intellectual property issues that continue to develop today. Mr. Knudsen also participated as a panel member and on an individual basis in several lecture series including new and developing employment issues in California.

In 1995, Mr. Knudsen was hired by a firm client, the Shepherd Group. From 1995 through 2002 Mr. Knudsen was General Counsel for the Shepherd Group in Southern California with direct responsibility for a $75,000,000 real estate and personal property loan portfolio as the managing officer and director. During Mr. Knudsen's tenure, the portfolio grew from $75 to $100 MM with record profits. The Group included the last private airstrip in the Los Angeles basin with both fixed and rotary wing aircraft, the Southern California Caterpillar Tractor Dealership, with approximately 600 employees, and an in-house printing and publishing division with a series of quarterly industry publications. As General Counsel, Mr. Knudsen was solely responsible for all litigation matters, handling litigation directly as well as managing outside and insurance-appointed counsel.

While at Shepherd, Mr. Knudsen successfully and single-handedly litigated a complicated 50-year-old easement matrix dispute against the largest cemetery in the United States, Rose Hills Memorial Park, ultimately saving downstream landowners millions of dollars in annual maintenance costs.

Mr. Knudsen left the Shepherd Group in 2002 when the Shepherd family sold the Caterpillar Dealership, and joined his former Crosby, Heafey, Roach & May colleagues, Tom Seltz and Neil Gieleghem in the Century City law firm of Gray, Gieleghem, Seltz & Knudsen. Mr. Knudsen remained a partner at that law firm until 2007. While at Gray, Gieleghem, Seltz & Knudsen, Mr. Knudsen's practice involved both business litigation and transactional matters.

While at Gray, Gieleghem, Seltz & Knudsen, Mr. Knudsen co-chaired a bad faith insurance contingency litigation matter involving general liability and umbrella carriers. After liability verdicts against both carriers in a phase I trial, Mr. Knudsen and his partner Tom Seltz settled the matter for $3 million dollars.

Beginning in 2003 Mr. Knudsen participated in the turn-around of a California-based security business that was near bankruptcy. After a three-year restructuring, Security Industry Specialists, Inc. became, and remains, one of the most successful security firms in the Western United States, with Apple Computer, eBay and the Academy of Motion Picture Arts and Sciences among its clients.

In 2007, Mr. Knudsen relocated to the San Francisco Bay Area so that his wife could attend the University of California at Berkeley, and in 2008 Mr. Knudsen re-joined his former Crosby, Heafey, Roach & May colleague, David Commins, at Commins & Knudsen, P.C. in San Francisco.
