The firm has grown via a blend of organic and inorganic growth in different parts of the US.

Robertson Stephens Wealth Management has reached $5 billion in AuM by adding a new firm to its network.

The new firm, based in Connecticut (pictured), is the Thrush Group, run by William (Bill) Thrush and Meghan Rump. It manages more than $180 million in advisory assets. Thrush and Rump join as managing directors.

As a result of the addition, Robertson Stephens now has about $5.1 billion in advisory assets across 19 locations in San Francisco, Marin County, Menlo Park, Santa Rosa, Pasadena, San Ramon and Burlingame (California), New York (NY), Valley and Boise (Idaho), Holmdel and Madison (New Jersey), Austin and Houston (Texas), Seattle (Washington), Denver (Colorado), Boston (Massachusetts), Jackson (Wyoming) and now Westport (Connecticut).

With more than 40 years of experience, 20 of which are in the financial services industry, Thrush specializes in developing and managing financial strategies for private business owners, corporate executives, and finance professionals. Prior to Robertson Stephens, Thrush was managing director and partner at The Thrush Group. Previously, he was a senior financial advisor and senior vice president of Wealth Management at Merrill Lynch. He has also worked at UBS.

Rump has worked in financial services and wealth management for two decades. She was previously MD at The Thrush Group. Before that, she was, like Thrush, also at Merrill Lynch. 

In October last year, Robertson Stephens Wealth Management, which operates across the US, expanded its presence in San Francisco's Bay Area, and has made expansion moves in California and Boston. See here for comments from the firm about its strategy and positioning.
