Pure Financial Advisors, a Mission Valley-based financial planning and asset management firm, said it is opening an office in Woodland Hills on Feb. 23.

CEO Michael Fenison said the expansion was caused by its rapid client growth since it was opened in 2008. Pure Financial now has about 1,200 clients and passed $1 billion in assets under management last year.

The new office, the company's third, will be managed by Ken Benedict. Fenison said his goal is to open three more branches in the Los Angeles region within the next 24 months. The firm now has 45 employees, a spokeswoman said.
